Wiring 2 lighting circuits using one 6 terminal junction box

[Paul Langham]

Yes you can provided you keep the switch returns to separate terminals. A junction box is not necessarily restricted to a single function such as switching.

That's what im worried about as there is only 2 terminals for SL in the junction box and these have been used up by the first switch

It is the same principle, if you know how connect one switch cable repeat this with the second except the switch return goes to its own terminal. Neutrals and cpcs are commoned to the same terminal.

So the second switch cable can be terminated in one of the loop terminals and one into a neutral terminal ?

Excuse my poor drawing. I have connected the first switch and put the line supply into the second can you see where the switch return now goes.

Hi westward i have got to go to work now but i will have a good look when i get back, many thanks for your help

The best thing to do if your not sure of a circuit is to draw it out as westward has done. I find it helps to see it set out on paper.
As for your lecturer not being not helping enough get him to go over it until you understand. if you are struggling the rest of your class will probably be the same.

Thanks mate, yeah I know a few probably are struggling TBF, he makes nothing clear, I'm thinking about putting a complaint in to the college

TBH with you all, I suffer with PTSD and get stressed really easily, I had to walk out of the practical session last Thursday because I just couldn't get my head around it, but that's why I enrolled on the course, I am trying so hard for the PTSD to get the better of me anymore, thanks for all your help guys !

Hi Westward i think i have cracked it now, and think i know why there is the need for a connector block, to join switch live to light live on 2nd light, thank you for your diagram, it really helped !

 

[westward10]

You shouldn't need any block connectors with the six terminals you have.

A description of the joint box might help. Is it the round hard plastic type with brass screw terminals ? Or is it the MF type with pre labelled terminals ?

5 terminals :

Pl
Sl1
Sl2
N
CPC

But there is only two SL terminals in the JB, enough for one switch

Pl
Sl1
Sl2
N
CPC

Would this work ?

 

[Andy78]

Right, it looks like you are using a Hager J501.
This raises questions like ..... why is your college teaching you to use junction boxes when unnecessary connections should be avoided on new installations, and why is your college teaching you to use equipment/methods not suited for purpose ? If you have to use extra connections jammed in there it's the wrong kit or the wrong wiring method.

That isn't a six terminal junction box as previously stated it is four terminal and not suited to the task.
