Got a call out to a customer’s premises in Dalkey on Friday. The lights on the stairs were tripping out the MCB. This circuit also included emergency lighting. The batteries on the emergency lighting had all run out so there was no lighting on the stairs. I located the problem and isolated it from the circuit and had all the lights on the stairs working by 6pm on Friday. The customer was very happy with the quick response.
It is important that all emergency lighting is checked regularly and a record kept of the tests. It is also a legal requirement.
