dimmer switch basics Ask questions and find answers to many subjects relating to electrics and electrical work

I'm runing a cable from an existing wall socket, up behind the drywall to the ceiling and across to a ceiling rose. I've now had the idea of adding a dimmer switch in-line.

What is the proper way to wire the switch? I believe I only need to interrupt the live wire and place the swithc in-line. Is it alright to leave the earth and neutral lines intact?

Yes you can leave earth and neutral lines intact.

You say running from existing wall socket. If you are referring to 13 amp socket you will need a fused connection unit before using to feed a lamp as the normal light fitting is only rated at 5 to 6 amp and 13 amp socket supply is in the main 32 amp.

By using grid switches you can include a dimmer and fuse in the same unit.

Thanks for the quick response. I'm actually drawing off a 5amp lighting socket, so I should be ok, no?

One quick follow-up...if I'm running the line along a finished concrete ceiling (unpainted), would you recommend self-adhesive trunking or conduit (or nothing at all)? Also, must I use a ceiling rose to remain compliant (the lamp includes a plastic connector)?
