Lighting with contactors and Emergency lighting wiring

[gerard]

Hi,
As part of my college project I have to design the electrical system for a supermarket.
The florescent lights are switched using contactors. These contactors will be switched by a bank of switches at the entrance to the premises and the contactors will switch on the lights when switched. How do I go about wiring this? Also, there are emergency fittings that will require an unswitched live to feed the battery.
Can anyone recommend a way of going about this - in the simplist way possible!!!

Cheers.

Hi Tony,

I am doing an electrical course at the moment and just seen your post re contactors and lighting for Gerard. Just a couple of really silly questions. 1. which is your neutral in the diagram? 2. It is supposed to feed the coil as a control wire along with a switched live? 3. Are your switches in the diagram intended as key switches for emergencies or for the flourescent lights. Can't think of any more silly questions. I understand the coil operation through electromagnetism and all that but i have trouble following very straightforward diagrams.

Many thanks,

Neutral is the bottom conductor with links fitted

The switches can be any kind of switch you like, it acts as a control for the contactor
