    What regulation would stop the use of Irish (6192Y) T+E Cable to BS 6004?

    I understand that in Ireland domestic single phase wiring is done with 6193Y cables that have a CPC that is the main size as the phase and neutral conductors and is insulated. Can anyone tell me what regulation in the 18th Edition (if any) would prevent this cable from being used in the UK?

    Installation is in fair condition and to comply to current Regs would require a rewire/upgrade.

    The above statement was made in an EICR which I was asked to look at. In my opinion they are on the wrong side of Trading Standards to suggest that an installation should be re-wired because it is not up to current regulations. If it is safe then I would not suggest to a client they must have a...

    Does anybody know of this new regulation that omits the ZS test.

    On another forum about an high ZS reading about a fused spur feeding a boiler, someone replied that in the new 18th regs if the RCD breaks the circuit within time under test you do not need to check ZS, just R2 continuity test for CPC continuity would be good enough. You just put N/A on the...
