Advice on LED inductive voltage preventing LEDs switching off
Hi, I'm looking for some advice on LEDs that glow when switched off in a multi-switch circuit. Last month I replaced our old CFL lamps with multiple LED G9 'chandeliers'. The living room has a dimmer switch and the 20-odd LEDs all work fine. However the hallway has 3 ceiling fixtures, with...- Stagbeetle

Control Of 1/2hp Motor Using 20a Sp Switch
This is an existing setup and I am wondering whether to modify it. It's not easy to get at so if I don't need to, I won't. I'm not sure if it will become part of the fixed wiring or whether it will be connected via a 13A plug, probably the latter, but basically we have a 370W (1/2hp) cap-start...- Lucien Nunes
