City and Guilds project. Drawing

Are your emergency lights meant to be maintained or non maintained? You can have several emergency lights on one circuit it does not need to be one per mcb, they can even be wired off an existing lighting circuit in some circumstances or if they were combined fittings. Exit box is fine wired off other em lights. You also need to think of how to switch the emergency fittings for testing purposes, generally keyswitch etc.

Emergency lighting is governed by BS EN 1838 and BS 5266-1 However I can't see C&G requiring students to know of them or have them, thankfully there are easy to follow guides out there from NICEIC and other organisations.

I used the standards, niceic pocket guide and ICEL 1006 (Google should bring up a fantastic PDF) in my design project (8202-30 - Car Garage/Workshop) and got a distinction so I'd say put a little time in, get a baseline knowledge, apply and reference it.

One other thing; use acetate sheets, you can get them in A4, A3 and larger - this will allow you to show 1 circuit per sheet and quickly 'declutter' your drawing of circuit routes; Sure you'll start of with nice colours; red, blue, yellow, green etc but there will come points where you'll one inevitably overlap circuit routes and it'll just appear as a brown mud-like mess - Put a bit of forward planning in and make it easier for yourself and the examiners as it makes it easier to fight, should thr need arise.

I completed this project a few months ago and wasn't required to fit emergency lights. If you want to push yourself, by all means, but don't get too stressed about using them if you cant work it out.

Thank you everyone. Especially for guidance. I will use it)
