hi, i though someone on here might have a quick answer to this.
I've been called to a house because the builder has changed the face plates on the switches for the hall landing and now the lights are not working at all.
I only had a quick look, and this is what i found.

I'm an not that familiar with TNCS systems at all, as almost every system I work on is TNS. My question is this, is there a way to tell if a system is in fact a TNCS system. There is one I am currently working on which is labelled as PME, but rather that taking it as gospel that this means it is...

This is a something that is concerning me about solar PV instillations.
What is stopping someone from using a isolated transformer with a bridge rectifier to give a dc output and feeding it back into the inverter while on economy 7 rates during the night at 7p per kwh then selling it...
I have been asked to test my friends renovated property, fully rewired, and said i'd do it for £100. He is a qualified spark but i did check his 1st fix work to verify his workmanship and all seemed ok to me. It has if i remember - 3 rings, 2 lighting circuits, cooker, smoke alarms, 2nd small...

I am not that keen on gluing...
