I don't have any earlier regs. that...

Regulation 411.3.3 for socket outlets up to 32amps and regulation 411.3.4 for lights.

Hello all,
I've found myself left with a small amount of wiring to do to complete an installation. It's a Heatmister UH8-RF unit being wired to a Drayton 2 way valve. The boiler engineer has done 95% of the wiring and has not gone sick long term.
I'm left with only the remote 'fire the boiler...
