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

As the title states : can you have two separate circuits in one box junction box ?

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

Obviously!! lol

So I posed a similar question a couple of years back and decided in the end to use separate JB's

So could you - yes

Would you - probably not!

 

[Silly Sausage]

Labels or not, by following safe isolation procedures, one would test everything is dead!

As the title states : can you have two separate circuits in one box junction box ?

Yes. only a label complying with 514.11.1

 

[jamie-spark]

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 !!!

Nothing wrong with that.

Technically only label complying with 514.11.1 is needed but most people follow good practice and fit a 400v label ( although it is not required )

 

[ChrisElectrical88]

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.

I have done it a few times but would rather put 2 2 gang grids in that a 4 gang 400v.

To the OP what exactly do you mean when you say junction box? Cause to me that's a small brown thing!

 

[Andy78]

I know of two small brown things. One is a junction box. I treat them both with the same level of respect.

Also to note their is nothing wrong with having 400v within a switch bank as its common practice outside the domestic arena - previously you had to label with 400v but i believe its not required now.

You can have 10 if you want.

For the sake of a quid?

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

Which regulation does it not comply with?

 

[Badged01]

Which regulation does it not comply with?

You've got me with that question, i dont know! I give up, what regulation doesn't it comply with?

 

[LeeH]

Of course you can have multiple circuits in 1 enclosure.

It's barmy if anybody argues differently.

 

[old_sparky_RE]

Correct Darkwood:- 514.10.1 needs a label if above 230v to Earth, or in an area / item where you wouldn't expect elec.

 

[richy3333]

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?

Mike, Tug the cables really really hard and take up the slack

My thought process here was for example 2 lighting circuits in one 20A JB, neutrals doubled up, think my thought process went put of the window...
