How to find a circuit breaker from the socket with HT38. HTInstruments
Circuit Breaker Finder
HT38 is essential to identify the circuit breaker protecting a given socket on a panel board without having to dissect it.
HT38 includes a signal generator (HT38T) to be connected to the socket under test and a signal receiver (HT38R) capable of ''exploring'' all RCCBs of the panel board.
