using a light switch as a JB.

Am I missing something here?

Loop at the switch is a great way of wiring lighting. I do virtually all my circuits like this.
 
Fill some of mine with wago (actually the Hellerman Tyton ones cos their better) connectors sometimes - lot easier to park earths and neutrals (often put mine in switch). On multi-gang switches one supply twin and earth cable and a separate permanent live to each switch from connectors. Beautifully neat. (i use deeper boxes)

Hope so, sort of.

Insofar that what I hope is that EddieM wasn't sighing at that, but had found a switch under a floor/above a ceiling/etc being used as a JB....

'cos if not, it's I who is missing something. :(
 
How about an old CU used as a joint under a floor?

Under floorboards I once found an FCU used as a JB. One of the oddest things I came across.

I went to a house where the customer had a spa bath that wasn't working. Established the supply was dead as a dodo.

Traced the cable back along the landing... hang on, what's this?

An old stand-alone Wylex RCD screwed to the joist under the floor. It had tripped. :roll:


I love this method of wiring too. I like to send a 3 core up to the ceiling, in case a permanent live is needed up there in the future.
 
Nooo. The light switch acts as a JB to a radial power circuit.

:oops:

That should have read acted, it doesn't anymore. Just one final thing. The RCD tripped out a couple of days ago, needless to say I suspected my work, being the only recent change. On checking the earth wire to the new light fitting was loose, not floating or in contact with anything live just loose obviously I've secured it properly now but why would a loose earth (whilst potentially v dangerous) cause an RCD trip?
