Following on from my borrowed neutral thread, I really liked the idea of installing an emergency above my C/U to provide illumination in the event of a fault.
A couple of points to clear up though:
- I was planning on putting it on it's own 6a MCB, however I've been thinking, if it's the downstairs lights RCBO pops, it won't come on (is a NM fitting). I could just put it onto the D/S RCBO or:
- To overcome point one, I could replace the light in my understairs cupboard with the em. fitting (on a seperate mcb) and have it switched (in reverse). But, does anybody see any problem with somewhat frequent switching of an emergency light? I know it will drain the battery sooner rather than later, but that's not an issue, I can replace it when it fails
- In terms of cabling, I see as I have three choices (light will be 1.5m from the C/U),
1) T+E clipped direct
2) Conduit + Singles (or T+E)
3) SWA or similar
I am not a massive fan of T+E clipped direct, and honestly, not a massive fan of conduit, I also don't fancy making some of the required bends in conduit. However I do think the cable needs to be something a little meatier than T+E (i'm not expecting it to be nailed into or anything, but the c/u is in a fairly full under stairs cupboard, so I don't want to take any chances.
Question is, is SWA overkill? I'm fairly confident working with SWA so have no issue using it, but if there are better options to explore I'm willing to, I see TLC do NYY-J which seems like it might provide the right level of protection and be a little more manageable than SWA.
Any other points to consider are welcome.
It's just a simple 8w emergency bulkhead
