The Megger MFL205 is a simple to use instrument, designed to help identify an individual fuse or circuit breaker on a fuse board or within a consumer unit. Using industry standard 4mm connectors, the MFL205 transmitter can be directly connected to a circuit using the supplied crocodile clips or - with relevant adaptors - be connected to a mains socket outlet or a light socket of the circuit that the fuse or breaker to be identified, is protecting.
