    Earthing

    Hi guys,is it ok to borrow earth from socket to light switch which is unearthed.It is all about changing plastic switch to metal one.The socket is underneath and probably the easiest way to do this if you do not want to rewire the whole circuit.Thank you in advance for all the answers.

    Hot tub earthing

    Been asked to run a supply for a hot tub, looking at the spec on it online. Comes on a plug top but it also says you need to run a separate earth out to it, anyone else ever had this? Surely the earth will come from the plug top. Seems a bit overkill

    metal boxes earthing

    I have seen a few metal back boxes that have no earth terminal lug. Do the regs state the metal back box must have an earth wire to it? The earth on the socket/FCU is earthed to the backbox via the socket faceplate securing screws.

    Earthing with solid rock below surface - burying tape for lightning earth

    A quick search for earth tape didn't come up with much, though this thread was of interest. I'll start by mentioning that I've led a sheltered life and only ever dealt with PME (TN-C-S) so never had to deal with earth rods. At our church, we've had an inspection of the lightning protection...

    Earthing on TNCS

    I realise this overlaps with the Earth Rod install post a little, but I am attempting to plan part one of an upgrade. Currently I am mostly confident I have TNCS supply (there is a query with the DNO to confirm) but I am a little confused by the additional strap to the lead sheaf in a TNS kind...
