Wiring Emergency Lights With Normal Lights on the same Circuit?

[TheConduitKing]

Hey Everyone,

Currently at work I've been tasked with wiring the emergency lights. As I've never done it before, and my foreman wants me to learn how to do it. It's wired in a way he's not familiar with, but he eventually got his head around it. It's maintained em lights wired with normal lights. That's kinda what's confusing me a bit.

It's two rooms. With a switch in each room. I've attached a picture that should hopefully make some sense. If anyone knows of a good guide or something to read to explain the different ways of wiring Emergency Lights that would really help. As I can't quite seem to figure out the logic of the wiring. The lights are wired with no Neutrals at the switch. The LNE going to the switch in the picture are to be taken to the first light in the smaller room and a live linked over to the other switch. Sorry if that's not clear in the drawing.

Thanks in advance.

What many people do is run the permanent line from the test facility to all points and just utilise it at the emergency lighting. So you are essentially wiring as you would do for any other lighting circuit, you just have an additional line conductor. What is the wiring method.

Yes, sorry I should have been clearer. It's Singles in Conduit and Trunking.

Also all the lives are brown. We don't have any black or grey cable. So I'm just trying to make sure that I label everything correctly so that we don't get any cables mixed up.

Are you using Klix roses.

Are you using Klix roses.

Yes. 3 and 4 pin

It's pretty straightforward just wire as normal with a separate permanent line. It will probably share the same route as the other conductors.

Am I going in the right direction with this approach? lights-2 hosted at ImgBB - https://ibb.co/WBTZQ95

He said I should have 4 browns at my switch in the hall and the switch in the smaller room will have a live going straight through the switch to the light. He said that I did understand at one point then confused myself.

Not sure what to do with the switches then? I should have a link between them.

Is the key switch on the same plate as the normal switch and how many normal switches are there.

1 key switch beside the board and 2 normal switches.

So they are two separate one gang switches, one in each room.

Yes they are two separate switches. And I believe they are 1 gang. But not 100% sure.

 

[westward10]

If it is one gang I can't see how he gets four browns, a two gang switch then yes.

 

[TheConduitKing]

If it is one gang I can't see how he gets four browns, a two gang switch then yes.

Yeah I'm not too sure. It sorta threw me. I'll have to double check but I don't think they are 2 wayed or anything. Just two 1 way 1 gang switches.

You need to be sure of the switching to comment further.

Yeah. I'll ask him to explain it to me and maybe draw it out. It needs to be right because the conduit Is under the floor and concrete it being poured over it! Can't fix it then without digging up the floor!

I'll report back once it's wired how it's done.
