When many of us in the electrical contracting industry think of temporary electrical installations, we tend to think of the wide range of short-term installations such as public or private exhibitions or events, parties or events associated with the entertainment industry like touring shows, theatrical, radio, TV or film productions. But in fact, temporary electrical installations are usually required at some stage for a range of new building projects, large and small, and even existing buildings can be subject to temporary installations. A temporary supply may also be required where a building is to be demolished or even needed due to unforeseen circumstances, such as failure of critical supplies. In short, temporary supplies are an integral part of the electrical installation industry. This article will address the topic of temporary electrical installations. We’ll discuss two specific scenarios, each requiring temporary supplies for different reasons and each having very different loads. We’ll then review some issues to consider when installing temporary power supplies. Scenario 1 – a data centre In a large data centre, a rising busbar with a source from an air circuit-breaker (ACB) rated at 3,200 A, supplies main switch panels each of which, in turn, supplies critical IT loads and their associated supporting infrastructure, such as cooling equipment. Due to recent flooding, the main busbar has shorted out, resulting in a loss of supply. An uninterruptible power supply (UPS) had been installed. The UPS system is comprised of a battery system to supply IT equipment during short-term outages, backed up by diesel generators. When the supply failed, the UPS system took over and performed as intended. However, a replacement busbar had a six-week delivery time and there would be a further delay to allow for its installation due to business critical issues. A realistic estimate was that it could take two to three months to replace the busbar. The manufacturer of the generators advised that the generators couldn’t be relied upon to maintain the supply adequately for that amount of time. To ensure resilience of supply for the critical system, a decision was taken for the temporary installation of cables to replace the rising busbar to power the critical loads until the replacement busbar could be installed. The cables could then be run from the original ACB to the main switch panels supplying the critical loads. Scenario 2 – a construction site In a large construction site, the site project manager had underestimated the power requirements for the site and separate generators had to be installed to provide temporary supplies to the tower crane, hoist and maintained lighting for flats under construction. A document of interest is BS 7375:2010, Code of practice for distribution of electricity on construction and building sites. BS 7375 is referred to in two notes in Section 704 of BS 7671 with regard to PME earthing facilities and Regulation 704.411.3.1 places restrictions on the use of PME earthing for an installation falling within the scope of Section 704. Most construction sites are provided with a TT supply which requires an RCD to provide automatic disconnection in case of a fault. Regulation 704.411.3.2.1 states that an RCD with a rated residual operating current not exceeding 500mA must be used (consult this Regulation for the complete requirements). Guidance on earthing is contained in BS 7430:2011, Code of practice for earthing. Temporary electrical installations and BS 7671 Temporary electrical installations can carry risks, even in the most benign of environments. BS 7671 applies, not only to fixed installations, but also to temporary installations. There is no relaxation of safety standards in BS 7671 for temporary installations. BS 7671 defines a temporary electrical installation as an, ‘Electrical installation erected for a particular purpose and dismantled when no longer required for that purpose’ (Part 2, Definitions). Regulation 110.1.3 states that, in some cases, BS 7671 may need to be supplemented by the requirements or recommendations of other standards and, included in a list of examples is BS 7909, Code of practice for temporary electrical systems for entertainment and related purposes (item ix). Running temporary cables The cross-sectional area (csa) of the temporary cables must be adequate for the loads to be supplied, taking voltage drop into account together with any applicable rating factors. When running temporary cables which are buried in the ground, the general requirements for buried cables given in Regulation 522.8.10 must be consulted. That is, the cable must either be run in a conduit or duct or else have an earthed armour or metal sheath, or both, suitable for use as a protective conductor incorporated. Buried cables, conduits and ducts must be buried at a sufficient depth to avoid being damaged by any reasonably foreseeable disturbance of the ground. A depth of 0.5 m is generally considered as a minimum depth. When running temporary overhead cables, the guidance contained in Appendix G of IET Guidance Note 1, Selection and Erection and also in Table D2 of the IET On-Site Guide is applicable. Generally, overhead cables must be suitable and adequately supported with a maximum length of span of 30 m and a minimum height above ground of 5.8 m where vehicles may run underneath and 3.5 m in areas inaccessible to vehicles. Guidance for running underground and overhead cables in specific circumstances are given in Sections 708, 709, 730 of BS 7671. Conclusion There is no limit to how long a temporary electrical installation may remain in operation and the designer must consider the possibility that it might remain in operation for longer than anticipated and design the system accordingly. When designing temporary installations, the risks must be assessed, and certification must be provided in accordance with BS 7671. Table 3.2 of IET Guidance Note 3 Inspection and Testing contains recommended initial frequencies of inspection of electrical installations. Temporary installations are not mentioned specifically but the recommendation that construction site installations should be inspected and tested every three months seems reasonable to apply to temporary installations.

Shocking figures from the Office for National Statistics show that over 291,000 residential burglaries took place across England and Wales from July 2018 to June 2019, with an even more surprising fact that a burglary in the UK takes place every 108 seconds. Property owners are not only left with strong emotional consequences to deal with but also high costs. In fact, the average cost of a residential burglary can sum up to over £3,000. This value is significantly higher for luxury homeowners, where target items for theft include cash, cards, wallets (identity theft), purses and jewellery. There is no doubt that luxury properties are a prime target for theft and vandalism, so when in the planning process for your new build, make sure you research all options for physical security. The security market currently offers an array of solution for protection such as CCTV, alarms, security shutters, gates, etc. Keep in mind: addressing physical security at an early stage of construction widens your options; this can be a little more difficult if it were at a retrofit stage. Below you will find brief tips on influential factors to be aware of. Prevention is key Complete an in-depth assessment of your property’s potential vulnerabilities. This will allow you to identify threats and provide a better search journey for risk mitigation products. Properties that do not have security measures in place are 5 times more likely to be broken into than those that do. An intruder will be inclined to target properties they deem easy to break into and can be out of in less than 10 minutes. You can find products that are security rated and can delay the duration of an attack long enough for response teams to act. Making a property appear secure from an external point of view will discourage burglars from even considering your home as a target. Location Understand the risk implied by the location of a property. Densely populated areas such as inner-city properties, particularly in London, are at most risk. Nonetheless, prestige properties in more rural areas often also see attempted burglaries. Properties located in strong weather areas must also be protected from natural means such as wind, rain, hail, dust and extreme heat. Consider the risks implied if your new build will be empty for extended periods of time, for example, if it were a secondary home. Strategic planning Location also plays an important role within strategic planning due to the potential legal problems an owner can encounter. Individual councils and local authorities will have their own planning policies and design guidelines, making planning permissions for properties in London, for example regarding external shutters, often to be difficult. Similar restrictions can apply to historic domestic properties in order to preserve their architectural integrity and character. It is highly recommended to contact your local council regarding planning. Conclusion Planning physical security for new properties should be approached with a strategic mindset and aiming to reduce costly consequences in the unfortunate case of an attack. Taking advantage of a new construction at an early stage will also reduce costs of repairs and reparations on physical security over the first few years. This will also benefit owners by giving them wider options for selecting fixtures and fittings to tailor the property to their taste.
SELECT, the trade body for electrical professionals in Scotland, has welcomed a small but significant upturn in the number of young women undergoing apprenticeships as electricians. Figures gathered by Scotland’s largest trade association show that there are now 13 female apprentices training to be electricians in 2019-2020, compared to seven in 2018-2019. Fiona Harper, Director of Employment and Skills at SELECT, said: “This is excellent news, coming as it does in Scottish Apprenticeship Week, which runs from 2 to 6 March. “An electrical apprenticeship for a young woman, just as for everyone else, is a life-changing experience which can open many doors, not only to further career progression and global travel, but also to professional regard and life fulfilment.” To mark the occasion, SELECT has commissioned a short film, The Power of Apprenticeships, which features an interview at a member company in Falkirk with one of its female apprentices, Neave Brownlie. The TClarke trainee says: “I finished school and could have gone to uni, but I preferred the idea of being paid while I was learning to become a qualified electrician. “I’m enjoying it; you’re never left alone on site, there’s always someone there supporting you and making sure you are safe. I’m treated like a daughter or a sister and everyone I’ve worked with has been lovely. “The exciting thing is the opportunity to travel the world once I have completed my apprenticeship and become a qualified electrician.” The Power of Apprenticeships also features another TClarke employee, Elyse McBride, a qualified electrician who is now office-based and is training to become a quantity surveyor. Elyse – a former SJIB Apprentice of the Year finalist in the SELECT Awards – said: “Completing an apprenticeship as an electrician was fundamental to me moving into a managerial role. “There are any number of different paths that can be followed as a qualified electrician, and the career world is your oyster.” Filmed at TClarke in Falkirk, and now available to view on SELECT’s YouTube channel, the video was produced in partnership with the Scottish Joint Industry Board (SJIB), the Scottish Electrical Charitable Training Trust (SECTT) and Unite the Union. Ms Harper, who is also The Secretary of the SJIB, added: “There is a world of opportunity for young women in the electrical sector and with this film we hope to encourage many more of them, currently in school or college, to consider an electrical apprenticeship as a serious career option.” Founded in 1900, SELECT is Scotland’s largest trade association. It has nearly 1,250 members businesses with a collective turnover of approximately £1bn, employing more than 15,000 people and 3,500 apprentices. SELECT also delivers training courses to more than 3,500 electricians each year and is committed to regulation of the industry for a safer Scotland. The Scottish Joint Industry Board was founded in 1969 by SELECT and Unite the Union.
NAPIT has created a new publication which helps Landlords and Electrical Inspectors understand the new Legislation governing electrical safety checks within dwellings in England, which will be introduced from 1st June 2020, coming into force for new tenancies on the 1st July 2020. This new Legislation is a welcomed approach by the UK Government to increase the safety of private residential tenants. Complex and in-depth, it requires a fresh take on Electrical Inspections from Inspectors, and a new level of understanding from Landlords, to reduce the likelihood of failing to meet their obligations which can result in landlords receiving fines of up to £30,000. The guide will help understanding of the new Legislation and covers: •Legislation Requirements •Consequences of not complying •What is required for an electrical safety check? •Different Electrical forms, and where they are used •Coding of safety checks •Frequencies of Inspections •Competence requirements of Inspectors •Remedial works requirements •Record keeping •Assessing risk The National Residential Landlords Association (NRLA) have worked in cooperation with NAPIT on the production of the guide. Meera Chindooroy, NRLA deputy director for campaigns, public affairs & policy said: “The new electrical safety regulations coming into force in England in July will impact all landlords, and we were happy to work with NAPIT to ensure guidance to help them navigate the new rules is accurate and consistent.” Compliance with regulations is critically important is all aspects, but particularly when it comes to electrical safety. Electricians working in the UK must have a full and thorough understanding of the British Standards BS 7671:2018 Requirements for Electrical Installations, IET Wiring Regulations, known as the 18th edition for short. It is therefore important that electricians keep up to date through 18th edition courses. Mike Andrews, NAPIT Group Chief Executive, commented: “Our latest guidance book on the new Electrical Safety Regulations will go a long way to helping the electrical industry and Landlords understand and comply with their obligations to keep private residential tenants safe in their homes. As the National Association of Professional Inspectors and Testers, we are well placed to provide accurate and consistent guidance for the industry to follow. Electrical Safety is at the forefront of everything we do, and with the introduction of this new Legislation, we have made it easy for the industry to access the correct information and ensure electrical safety standards are met.” NAPIT members can pre-order their copy of the guide for £14.99; for non-members, it’s £16.99. Full RRP is £19.99.* FurtherInformation: Topre-order your copy visit www.napitdirect.co.uk/p/landlords-and-electrical-inspectors-guidance-for-the-private-rented-sector-electrical-safety-checks TheElectrical Safety Standards in the Private Rented Sector (England) Regulations2020: http://www.legislation.gov.uk/ukdsi/2020/9780111191934
The UK Government has on the 1st June 2020, released guidance on the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020. There are three sets of guidance with separate versions released for landlords, tenants, and local authorities in England. Private landlords must ensure: Electrical safety standards are met when the property is occupied during a tenancy. Every fixed electrical installation at the property is inspected and tested at least every five years by a qualified person. The first inspection and testing are carried out before new tenancies commence on or after 1 July 2020 and by 1 April 2021 for existing tenancies. Key questions answered WHAT DOES ELECTRICAL SAFETY STANDARDS MEAN? Under the Regulations, electrical safety standards mean that the inspection and test of the installation is carried out in accordance with the eighteenth edition of the wiring regulations BS 7671:2018 (the national standard to which all domestic wiring must conform). WHAT SHOULD I DO IF I HAVE AN EXISTING REPORT? If the landlord has obtained a satisfactory Electrical Installation Safety Report which is less than five years old, they should review the report to see what was recommended on it and consider how the property has been let since it was carried out. If big differences to the property have occurred, then it would be wise to get another check done. If no changes have been made, then the report will remain valid until the next inspection date specified. WHAT TENANCY TYPES ARE COVERED BY THE REGULATIONS? The Regulations apply to all tenancies apart from those listed as excluded tenancies which are social housing, shared accommodation with a landlord or landlord’s family, long leases, student halls of residence, hostels and refuges, care homes, hospitals, and hospices as well as other accommodation relating to healthcare provision. DO THE REGULATIONS APPLY TO HOUSES OF MULTIPLE OCCUPATION (HMO)? Yes, if an HMO is a tenant’s only or main residence and they pay rent, then these regulations apply to the property. Furthermore, these Regulations repeal the previous legislation which set requirements on HMO landlords. WHAT ABOUT NEW BUILD PROPERTY? The Regulations stipulate that all rented properties – even new builds – should have their electrical installations tested every five years. The Electrical Installation Certificate will certify that electrics are safe when they are put into service, but it will not identify any damage, deterioration, or defects that take place subsequently. After five years of use as a rented property, the UK Government believes it is sensible to ask landlords (who have not been living in the property) to ensure that the electrical installation is still safe. WHO CAN CARRY OUT THE CHECKS? Any Electrical Inspector employed to undertake the electrical inspection and testing within the property must have: Adequate insurance. This should include at least £2 million public liability insurance and £250,000 professional indemnity insurance. A qualification covering the current version of the wiring regulations (BS 7671). A qualification covering the periodic inspection, testing, and certification of electrical installations. At least two years’ experience in carrying out periodic inspection and testing See www.electricalcompetentperson.co.uk and www.napit.org.uk/member-search.aspx How do the rules interact with the guidance because of COVID-19? The UK Government recognise that the restrictions imposed by current measures to minimise the infection risks from COVID-19 may make carrying out electrical safety checks more difficult, for example where households are isolating or where an individual has been advised to shield. Under such circumstances, provided the landlord can demonstrate they have taken reasonable steps to comply, they would not be in breach of their legal duties.
The Building Controls Industry Association (BCIA) has released a new technical guide to add to its portfolio of online guides available to download. The new guide, The Impact of Controls on the Energy Efficiency of Buildings, focuses on the British and European standard, BS EN 15232-1:2017, which assesses the cumulative impact of building automation and controls – commonly referred to as BACS – on the energy efficiency of buildings. Terry Sharp, President of the BCIA, said: “It is a well-documented fact that buildings account for over 40% of global energy consumption, and buildings rarely perform as well as their designers calculated. BCIA member companies use the BS EN 15232 Standard as a guiding light for control system design and operation, so we have released this Technical Guide to help manufacturers and systems integrators understand the Standard better and improve the performance of the buildings they work on.” The BCIA’s technical guides are designed to help members and those in the building controls and BEMS industry work more effectively. All technical guides can be downloaded from the ‘resources’ section of the BCIA website.

Air purification is the removal of dust and other harmful impurities from the air using various technical means. Air purification by means of supply ventilation and air conditioning systems takes place in residential, public, and industrial buildings. In addition, air purification is used in various technological processes, such as oxygen production. The air is also cleaned by means of extraction from production buildings, followed by dry or wet cleaning in industrial plants. The air supplied to the buildings is cleaned from dust to create a favorable microclimate for employees and to prevent pollution of equipment and other elements of ventilation systems. Many technological processes of modern industrial production should be carried out only in premises where the air is thoroughly cleaned. Such air purification is most relevant for microelectronics and medicine, as well as for precision instruments, films, and photographs. Selection of means for air purification The choice of air purification agents depends on the requirements for air purification. Air purification, with the help of air filters, is the most common. These air purification filters are installed in the rooms of supply air ventilation, air conditioning, and air purification systems. Air purification at industrial enterprises plays a significant role in the system of environmental and health protection measures. Various filters are used for air purification and neutralization. For finer air purification, dust chambers, gas catchers, “cyclones” PVM units and other devices are used. Industrial air purifiers – how do they work? The air purifier can be integrated into the room ventilation system, or placed separately. Its task is to drive the air through special filters that capture dust, smoke, odors, and microorganisms, so that “at the output” the air is fresh, without foreign matter. If an air purifier is integrated into a ventilation system, the air is supplied to the filters by this system. If it is a separate device, then it works on the principle of air conditioner, “running” through the air in the room. By the way, certain types of cleaners can work in pairs with the conditioner. Such purification is also a great way to improve the microclimate in the room. By removing harmful impurities, dust, and bacteria, purifiers make not only the air cleaner. The general sanitary situation in the room is improved – after all, dust particles settling on the filters will not get back into the room, and thus will not settle on the surface of furniture and equipment. This is especially important for high-precision production and chemical and catering facilities (e.g. medical laboratories, precision optics plants, food processing plants, etc.). Many air purifiers have additional functions, such as the ability to saturate the air with ozone. If you have such a purifier, the room will smell like mountain air. Ozonation is a great way to get rid of pathogenic bacteria in the air and dust. It is also good for your health. According to research, people work better in rooms where air purifiers are installed as muscle and brain activity levels increase. If you want your employees to feel less sick and work better, buy this device.
