If the inspector is removing the front cover and has caused the misalignment, I’d be concerned that the devices and CU were still live as both the main switch and circuit breaker are indicating the ‘on’ position. They may well be isolated elsewhere, which we can’t tell from this picture. Safe isolation is of paramount importance and can’t be stressed enough. General requirements - updated in line with the very latest amendment to BS 7671 (specifically within Section 722)

That said, in this instance, we need to look at the likelihood that the conductors are accessible during normal service. It is essential to all those concerned with the design, installation and maintenance of electric wiring in buildings. The Codebreakers guide is the only one of its kind on the market and was crowned Top Product of the Year by Professional Electrician Magazine in 2018. The book features hundreds of EICR observations and their corresponding codes as well as detailed sample forms, information specific to the frequency of inspections and tests and information directly tailored for the social housing sector. Electrical Heating, Ventilation & Control (303) Apply Electrical Heating, Ventilation & Control filter This is the 5th edition of the IET's Code of Practice for In-service Inspection and Testing of Electrical Equipment.Codebreakers: Well, what can I say, there are modifications, and then there are “modifications”! The manufacturer may not allow this kind of modification to its boards, and we should stress that it shouldn’t be done. In this case, however, we have to look at the merits of the modification and the location. This dry lining type pattress box is being used in the absence of the correct barrier, which is most likely just a plastic shroud. The prospect of anything larger being there would need a call to pest control and not anything the electrical designer could foresee in a general installation. Things become a little more in-depth with thatched roofs, farms and remote installations, but the considerations here are generally confined to conductor and cable damage from wildlife.

MARTYN REES: New consumer unit required? Customer wasn’t sure if he needed any work doing on his mains end!!! Well, this one beggar’s belief. I’ll try and go through the issues as I see them. A No, Codebreakers gives a scenario and suggested observations, followed by an infringement and a code. For a different circumstance, it may be that the inspector wishes to choose different observation wordings or a different code, this is a real-world requirement and inspectors always have this option, however it detracts from the level playing field approach that NAPIT is striving to achieve.If the devices themselves were accessible to isolate and reset, there were no signs of mechanical damage, IP infringements, or thermal damage; I would see this as a C3. There is no potential threat to life in this scenario, however, there is room for improvement. Although at first glance this may seem to be a problem installation practice, in reality, there is unlikely to be a problem, and I don’t see as it needs to be coded; indeed, I’d struggle to find a Regulation that it directly infringes. There is also the reality that to remedy it would be impractical as the wall structure coverings would need to be removed entirely and replaced, which isn’t likely to happen. The initial information has been extended and now covers more information to guide contractors, inspectors, and clients through the pitfalls of this highly technical area of the industry. The threat from vermin damage of any kind is always a problem, which can be exasperated for installations in either rural locations or where access for vermin is unavoidable. In circumstances such as these,where damage can be expected, careful choice of the wiring system to limit or deter vermin should always be determined. Where damage has been found, especially in extreme cases such as this one, the potential for fire can be high, as well as increasing danger due to access to live parts. The use of metal/plastic conduit systems, trunking and armoured cables are all useful in protecting against vermin, but not always practicable, especially in domestic scenarios. After repairs are carried out, the installation of AFDDs could disconnect the circuit before any future damage could initiate a fire risk. AFDDs, however, won’t remove the vermin, so a call to a reputable pest controller would also be a good idea for the client. It enables the competent electrician to deal with installations (up to 100 A, 3-phase) providing essential information in a convenient, easy-to-use format.

Our goal is to provide one stop place for electricians and electrical contractors, but we are happy to help other clients too.Please let us know should you like to discuss anything and we’ll get you in touch with an electrician who can provide a professional advice! The key purpose of written publications is to aid contractors, inspectors, and clients has now been updated to align with the 18th Edition of the IET Wiring Regulations. As we look at this, it may seem there is an issue – some may say the cpc’s sharing the same sleeve is an issue, but in reality, it isn’t a problem, as they aren’t twisted together. Even from a periodic testing perspective, they’re very unlikely to cause a problem.
