It always has voltage to ground so I think I can assume that's my 'L' or 'hot'. I've tried connecting these two wires to my light fixture wires (and the ground to...

    Hey all! I'm trying to install a smart switch to control my 3 outdoor lights. 2 wall lights and a lamp in the yard. The house was built in 53, so I assumed there wouldn't be a neutral in the box, so I picked up a GE switch that doesn't require one. The switch shares a box with another that...

    Is there a max Zs for lighting circuits?

    I can't find anything related to this in the regs so I probably misunderstood the question. The way I see it the max Zs for any lighting circuit depends on the circuit breaker for that circuit. Say we have a lighting circuit with 100x36W ceiling lights which gives us a load of 16A, we choose the...

    Confused by the shear volume and what to do

    Good morning all, I mainly work on boiler faults, and repairs. I sometimes have to install wireless thermostats, or renew the fcu switch. I’ve seen a video by an electrician about using a ratchet crimp tool, and a plumber with the same. I’m after some advice as I’m thinking to use bootlace...

    Confused about Becoming an Electrician

    I'm moving to the UK shortly, and want to become an Electrician. In Ireland, where I come from, the process is simple - you do an apprenticeship. It seems that in the UK, you can either do an apprenticeship, or go the "Electrical Improver" route - do college diplomas, then work as an Improver...

    Maybe someone can enlighten me, as I am surely missing something here. I regularly read posts by people who are clearly really not competent to undertake work - yet members on here will give them what in effect is encouragement and part knowledge. No knowledge is dangerous but a little...
