can you have two separate circuits in one box junction box ?

If it's a EICR I would code 3 it!

As long as the circuits don't interfere with one another then yes you can.

Its an outside junction box with the shower cable in twin and earth coming out and jointed to swa then the garage cable in twin and earth going into swa

I'd use 2 IP boxes!

As above. Take it it's not 400v 3 phase then.

well lets put it this way----------how would you extend the circuits to a distribution board if it needed to be moved 2 ft away from it's current position and none of the existing cabling would reach?

That's different IMHO 2 ft away is very different to being remote from the CU

no its just single phase. could spilt them into two boxes but pointless if the regs allow it first.

A former supervisor of mine once told us not to wire two seperate lighting circuits into a multi gang switch, as there was the potential for 400v there.
Fine, but it was a single phase installation! he was adamant in what he was saying was right !!!

But the question is, "can you?" Not "would you?"

That old wives tale again, a label on the switch sorts that out providing of course the switch is sufficient as in a barrier between phases, I must admit I do not care for 3 phases in switches either.

How does he cope with 3 phase DBs then?

I would put a label in there to warn that its 2 different circuits.

Nothing wrong with it at all IMO, Labels should be used though In my view.

Beat me too it haha
