    Insulation Test before consumer change.

    Guys Is it good practice to zap the old wiring with a 500 volt insulation test before any consumer unit is installed? Or do you just go ahead and rip out the old one and fit the new? Zippy Trainee Sparky

    Something else to disconnect before testing...

    First came double sockets with integrated USB outlet, now BG has a double socket with USB and a built in wifi repeater. I think i'll just stop using 500v dc across L & N completely. I'm now waiting for double socket with integrated toilet roll holder.

    Why Earth before IR testing?

    A question for testers to settle a debate at work - GN3 & regulation 612.3.1 state that when doing insulation resistance, the CPC/armour of swa MUST be connected to Earth. Does anyone know why this is please?

    Will a B type 32 trip before a C type 16?

    Morening all, I have a dilema that you may be able to help with. Manufacturers instructions ask for the unit to be fed from a C Type 16Amp MCB. At the moment this is all the technical information I have. In one in twenty cases they experience nuisance tripping and have now recommended fitting...

    Blimey, never seen anything like this before!

    I was asked by a friend to connect up some lights in their store room. You can make out the cable on the ceiling coming out of the conduit ready to be connected to one of the CU's. This is what I came across. I said 'No'! :)

    Was it really that great before Part P?

    I have been reading posts on this forum for quite a time, and some people have been criticising Part P as though it was a wonderful world before Part P came along. I personally don't think it was so great before Part P, and I don't think it's so great now, but my point is that there were...
