    UK Live neutral terminal LED bulkhead.

    Evening everyone, I had new one today, a live neutral terminal on the connector of a LED emergency bulkhead. This fault repeated on 4 other units. The neutral was being taken from a 4ft fitting next door that a new guy had been messing around with. Any ideas why or how? Cheers

    Blown Switch - never had this before!

    We've got a overnight storage heater, fairly old but still going. That was until it starting tripping the RCD, so half the CU went off. The switch has a crack and upon investigation it was burnt out, melted some of the cable insulation too. Switch replaced, but radiator still isolated at the...

    Lighting cct - shared neutral

    Whats the best way of making good this lighting problem? In a dist. board, there are 3 x separate fuses feeding 3 x separate lighting circuits. However, the 3 circuits share the same neutral back to the distribution board. A notice has been given to put this right. It's impracticable to run out...

    UK Why is neutral at 0 volts?

    I’m confused why neutral is at 0v (or close too) in certain situations! TN-C-S system for this example, no borrowed neutrals or faults! A simple lighting circuit! Now I can understand that when the circuit is open neutral would be at 0 volts due to it being connected to the earthing...

Subsequently another electrician on visiting the house, unaware of this method (if it even exists!?) concluded...

    Neutral Pole

    Good day. This has always got me confounded. Witha 4-pole 63A breaker, can someone please confirm/advise what the current carrying capacity of the component is? Does the 63A current stamped on the product mean 1. 63A per pole? 2. A total of 63A but limited to 63A in any one pole? If #1 is...

    AC vs DC, live vs neutral

    Hi. I've read much about ac vs dc but can't find a 'simple' answer. If current alternates 50 times per second in a uk mains circuit, why do live and neutral not swap 50 time per second? On these forums, I've read that it does, so that copper does not migrate as it would in a dc circuit. I've...

    Floating or Bonded neutral

    I just bought a Westinghouse generator (When 12000) and my neighbor is telling me no to use it until I know for sure if it is "Floating Neutral" or "Bonded Neutral" I don't really know what is he talking about. Why does it matter?
