    NICEIC Certification Scheme comfused by NICEIC statement

    From the OP point of view it would have been better to have all wiring, plasterboarding, skimming, decorating, testing and second fix done in one day and all back boxes flush and level. Clearly the builder/electrician knew this as well would learn both trades otherwise?;):rolleyes: If they did...

    all i can say thier goes his xmas bonus.

    Shelving problem. that is one of the most basic risk factors in warehouses and all UK warehouses would have the ability to resist forklift collisions, plus weight limits enforced and regular inspections and repairs. It would be a serious breach of health and safety to rely on the skill of...

    Just joined, would like some advice on ELI measurement

    Sounds like you don't have any extraneous conductive parts (technically the earth rod isn't one even though it fits the definition otherwise), so there won't be any other paths. It's slightly safer not to have any, so you should be fine. You will actually be measuring part of the circuit as...

    £500 for a full rewire in 3 bed property

    Given the number of people who don't know the difference between a rewire and a new consumer unit i bet the are plenty who have no idea how hard a rewire is. And what a reasonabe price is. The so called electrician is the one in the wrong in my opinion.a professional would have walked away.

    Power supply to garden office question

    Sockets won't be limited and with 20A upstream you wouldn't need a board, just connect the sockets in a radial and lights on an fcu. The main questions are what size and number of cores in the swa, and what will be the zs and volt drop and earthing arrangements. You would also need to check...

    Chasing sockets brick blown

    If you make a hole by mistake, just tell the customer it's so they can feed an extension lead through and plug it in on the other side.

    Are the bloody Regs statutory or not?

    Correct Depends if the regulations are statutory eg the gas regs are but the electrical regs aren't. Correct, building regs would be less relevant here, that would come under negligence laws even assuming it wasn't done intentionally to cause a danger.

    Are the bloody Regs statutory or not?

    I realise there are time pressures but the judicial system is mostly set up to avoid miscarriages of justice. The legal system gets a bad name due to ambulance chasers getting settlements out of court before hand. by way of example of the legal process trying harder where things are more complex...

    Are the bloody Regs statutory or not?

    The court is not an expert in most things really, that's why they call witnesses who are experts. It's a normal practice. I am guessing we would be in chaos pretty quickly if courts made important judgements based on no professional knowledge.

    Are the bloody Regs statutory or not?

    Part P of the building regulations is part of the building regs, and approved document p includes the building regulation on the tinted background, together with non statutory guidanceo onways of complying. For practical purposes it doesn't really affect what we would do, but given the whole...

    Are the bloody Regs statutory or not?

    That's the approved document not the building regulation. Approved documents are just suggested ways of complying. Bs7671 is just one way of complying.

    Adiabatic Equation - why only for CPC?

    There's no prescribed order for designing your circuits, as long as they comply in the end. That wouldn't work if you have a fixed load not subject to overload, the nature of the load determines the necessary cable size along with adiabatic. A lot of shower circuits are on a higher ocpd that...

    Oh sorry assumed you meant part p, which building regulation were you referring to?

    Adiabatic Equation - why only for CPC?

    I'm not a spark so i have limited practical experience, but given 100A is the largest bs88 commonly used in domestic my supposition is that it would be ok. Of course all this only applies to tn-s, as if it's pme then that means that the incoming link to the MET and the bonding would be a current...

    Adiabatic Equation - why only for CPC?

    True but just to be clear, if the conductor is carrying normal current beforehand that just means the starting temperature is higher, so rather then starting from 20c it would start from 70c. Then when the adiabatic ie sub 5s fault event happens, that part is covered by calculating the energy...

    What about the sealing then?

    Good question, where do you drawer the line indeed! That was kind of my point, obviously i don't really think your way is a problem, but how about if we knocked out the whole back of the cu and mounted on timber? Still meets ip rating and the cu itself is non combustible but most of the back is...

    Adiabatic Equation - why only for CPC?

    Great question, it would certainly also apply to phase conductors, but that would only really be needed if the ccc of the cable is less than the reading of the ocpd, for example if you are wiring a 50A circuit with a door bell transformer at the end in 1mm singles. Normally a circuit wouldn't be...

    What about the sealing then?

    Ironically that would be making the wood part of the enclosure, and as we know wood is not non combustible, although i can't imagine a time when you'd have to defend that in court!

    Are the bloody Regs statutory or not?

    This is incorrect. The approved documents refer to bs7671 as a possible way to comply but nowhere in the regulations themselves does it mention them. Part p the actual part on the statute is very simple: "Reasonable provision shall be made in the design and installation of electrical...

    Neighbourly Electrical Harassment?

    This is very strange, i remember recently the American Embassy in China and also in Cuba perhaps had issues with workers becoming I'll with strange sensations in their bodies, eventually it was suspected some kind of interference like this. It sounds far fetched but there's got to be one person...
