Abstract:
The patent application describes a system for tracing electrical cables within a building, using in combination a pulsing electrical load and a standard clamp-on type ammeter. In operation the intermittent current flow can easily be detected and cables can readily be traced from outlet to circuit breaker. The novel pulsing electrical load draws current at a characteristic rate that is independent of the amount of current drawn, so that various load resistances can be used, to suit the circuit being traced. If desired, the standard clamp-on ammeter could be replaced by a detector designed for use with the pulsing load.
