Emergency Light wiring.

[Piratepete]

Hi Guys

I'm installing Non Maintained Emergency Lighting in a very small village hall - in the two loos and at the Emergency exit inside and out. Do these have to be on their own lighting circuit?
Additionally is a test switch required if the mains supply can be easily switched off without causing anyone any inconvenience?

Thanks
Pete

connect into local lighting. keyswitch/es preferred but i don't think it's obligatory.

If you take the feed from the local light mcb to a test switch, the emergency lighting can be tested without putting the hall in darkness.

If the local distribution board isn't accessible, just take a feed from a local light fitting and connect to key switch. If it is wired in conduit surface mounted, it may be just as simple to alter your switch from for e.g 2 gang to a 3 gang to accomodate your new test/key switch.

Thanks all. The Dis board is very local. I don't personally see the need for a test switch. All areas have windows and testing will be in daylight hours.

Make sure you use the correct cable T&E is not acceptable.

I'm intreagued by this, you are installing, yet seem not to know what you need, how did you quote??

Since when?? you only need to ensure you use fire rated cable on a central battery system.

cause you will need a perm live as well as switched

Fair enough, its been about 7 or 8 years since i put an E light system in, and i cant remember the cable BS number, but it was the same as FP200 but had a white outer sheath. I also had to rewire one that was picked up on a HMO because it was in 1.5mm T&E.

I stand corrected if my assumption was wrong.

please explain

if the toilets are less than 8m2 its not a requirement to have e lights fitted.

There non maintained squire...T+E will be fine...

For new builds I've seen battery packs connected to a separate circuit. Those breakers would have a lock on them at the panel so they couldn't be shutdown for any reason except maintenance.

How does that work then??

 

[erecrtrican]

Open up the panel and look at the directory. See if any other battery packs are connected to it.

Now come on Brightspark, how can you have a switched feed, a permanent feed and a neutral with T&E?

As I understand it (I may be wrong) non-maintained means that it's a separate light which doesn't come on with the normal light switch, not one of the existing lights.

I'm not aware that (in this application) you need a special cable but you do need 3core (in my opinion).

Given that in HMO's the emergency lights are usually fed from the local lighting circuit that is wired in T&E did this have to be rewired / upgraded as well or did you just have some jobsworth calling the shots that didn't have a clue
