The Martindale FD600 fuse finder kit allows for tracing of fuses through mains sockets, light fittings and points in a circuit where there is no power socket available.

The transmitter is supplied with a mains plug and a set of two wire test leads, emitting a signal for the receiver to pick up. The receiver's adjustment wheel increases or decreases the sensitivity. This combination makes tracing fuses much easier, even on a crowded fuse board.

The FD600 fuse finder is supplied in a hard carry case with a transmitter, mains plug, two wire test leads, receiver, batteries and instruction manual.
