    2 amp sockets

    Obviously an un-fused 2A plug/socket arrangement on 5A wiring protected by a 5A over current device has the potential to be overloaded, but in practice you would need to run over 460W off one single plug to do it. Sticking to lighting loads, which is what they are designed for, this should...

    Having power during rewire

    If he is doing the job properly he will probably disconnect the old installation completely and fit a small temporary supply. When he has installed and tested the new installation then change over from the temporary supply to the new. Sometimes called a 'builders supply'

    Moving my supply intake

    You are not merely advised not to do this, you are not allowed to do it. The supply cable and head/fuse termination and meter belong to the electricity supplier, not you, and you HAVE to get them to do it if you really want it moved, at whatever cost they apply. Having said that they may not...

    100mA RCD tripping problem

    So you still haven't got to the root of the problem that you were posting about in June. Reading back I think for a start you need to identify how the CU is arranged. It was asked back then if the 30mA circuits power off when the 100mA RCD is off to which you did not answer directly, but your...

    wiring appliances in kitchens

    There is always room behind appliances for a plug and socket and they are never to be 'jammed' up against the back of them anyway. I would never allow outlets of any kind to be attached to the units and should be fixed to the walls as the units are more temporary than the wall even if 'fitted'...

    RCD keeps tripping

    Of course you could do an IR test on the final circuits but one would assume you had already done that before connecting them up?

    RCD keeps tripping

    I would firstly put the earth in place and leave it there as this is a safety requirement and connecting and disconnecting it like that is a very bad idea. You then need to remove all the neutral wires from the final circuits and test that the RCD resets. Then reconnect the neutral's one at a...

    Getting rewire signed off??

    What does 'got part p' refer to here as this is an approved document? I assume if he is at least aware of part p that he notified it to building control before starting the rewire?

    "Moving Incomer" **pics included - updated-

    Surely this is a TN-S supply and as such should remain TN-S! A conversion to PME would make no sense and the earth connection at the supply cable's end looks sound.

    110v site trannys

    They are 240V single winding primary and two 55V secondary windings connected in series. The outside of the two series windings gives you 110V and the third wire is connected to the centre and is the earth for the output. Hence CTE or 'centre tapped earth' and you can now only receive a shock of...

    Incoming TT supply

    And of course you will go through all the testing and inspection required by BS7671. You are aware of part p also I assume?

    Running power to a caravan

    Needs to be 6mm² SWA for 32A over that length and would be good up to around 37m.

    Have you got the supply live and neutral in the same side ie. both in the top?

    underfloor heating RCD

    Sorry crafty you are right it is notifiable (for whatever that is worth!!)

    underfloor heating RCD

    Only if the heating is in a kitchin or bathroom, which it probably is!! Or maybe outside :shock:

    SWA cable, long run how to join

    Obviously by quoting 522-06-03 Spark123 has fully proved he is right and I can not believe that any claimed qualified spark would EVER consider installing an SWA or similar armoured cabled without the armour connected to earth at the supply end, whatever cores they use!!!!!!!!

    RCD tripping

    Are you certain you are putting the neutrals in the correct neutral bars? i.e. 'RCD neutral bar' for bathroom light feed neutral / 'non-RCD neutral bar' for upstairs lights feed neutral.

    Should I leave alone?

    The OP mentioned a 60A CU but no mention of the fuse rating.

    chasing in electric cables

    It is there for protection as said previously from plasterers trowel, but you still can't use it earthed outside the zones as protection from nails or other puncture, which is how your post read.
