Can anyone tell me, if installing non-maintained emergency lighting (the
ones the turn on when the power fails) is there any special cable
requirements, or can they just be connected like normal lights (Obviously
not to the switched existing lights!)
Do they have to be on the same circuit as the other lights in the room, so
if that circuit failed they come on?
Do they need a test switch that cuts the power to simulate a power cut, or
can one just pull a fuse/trip a breaker to test them?
