[QUOTE="green-hornet, post: 74760, member: 2683"] As Andy has already said the mcb could be used to test emergency lighting. However when local lighting circuits are used as supply for the emergencies it is often far easier to put test switches in local area's, this aids testing as you only isolate the ones on say that floor. I feel it is always good practice to put in a dedicated key switch for emergency lighting. MCB means all lights out for duration of testing for 3 hour backup! not good I would say and probably illegal in staircases where permanant lighting is required as per H&S guidlines. [/QUOTE]
