    Smart Switch lighting neutral question

    I own a commercial storage unit where I keep my boat, trailers, etc. I went to install a Smart Switch in it, so I could remotely control the lights if needed (i.e. some times I will forget to turn them off when I leave). I bought a witch, took the cover off, and realized I don't have a...

    Rcbo neutral and functional earths

    Thoughts on this please, functional earth leads obviously showing signs of heat damage, the greenish coloured neutral leads compared to the blue ones are coloured throughout their length, maybe heat has caused this?

    UK Standardising on site to TP & N Sockets rather than TP and no N

    Hi I have a site where they have some sockets fed via Three Phase and Neutral and others TP with no N. Rather than both types of sockets for both types of appliances, was looking at 'standardising' and upgrading all plugs to TP and N. And where the appliance did not need a N, it would be left...

    Smart light switch install with no neutral required

    I have just received a wifi switch that does not require a neutral. As far as I thought, it would then be a straight swap with the existing 2 gang switch. However, I can’t seem to see an Earth on this new switch and looking at the current wiring I can’t see how it would switch over. Any ideas? I...

    Neutral to a switch for future use?

    So I've seen some posts in the past about smart switches needing a neutral at the switch. I have a rewire coming up and was planning to use 3 core and earth as the switch line for some switches (2 gang switch will need just 1 neutral from a 3 core earth and the other SL can be T+E) as the switch...

    Need to add neutral slots to my 125 amp panel to match ground slots.

    I have an Eaton 125 amp panel with a ground bus bar with 24 slots and 14 neutral slots. I have a 6 breaker Reliance 7500w transfer panel connected to it. The main panel has 4 unused breakers. I need to increase slots on my neutral side. Can I add an additional neutral busbar to the existing one?
