'Last man out' switch

[D Skelton]

If you're wiring it as per Tony's diagram, as you have emergency lighting you will need a seperate 4 pole contactor with its coil wired directly and unswitched in to the overcurrent protective device for the control circuit to cover the four permanent line feeds.

I think you need a contractor not a contactor, if you dont know how to carry out this work you must be a 1st year apprentice, I dont know about you guys in the UK but our emergency lights have to be on a seperate cir with a test module (contactor and timer) so they can be tested every 6 months, if they were on the normal lighting cir you would have to power this down as well for about 3 hrs
