5.4 Identifying fuses in a switchboard
LKZ-720 system may be used for identifying safety devices in a circuit. In the analysed circuit a
current signal is forced, for which a protection is searched in the switchboard. The transmitter must
be connected to the circuit in a manner enabling the current flow in the circuit. Connection example
Fig. 27.
Rememberer that cables and busbars in switchboards / distribution boxes may falsify the indica-
tion of the receiver. To make sure whether the detected fuse/circuit breaker is in the tested circuit, re-
move the cover of the switchboard and approach the receiver directly to wires and try to locate the
circuit.
You may also continue the search using a wireless NCP probe (sec 6.4). Hold it in perpendicular
to the switchboard, remembering the arrows on the probe should indicate the top and bottom the
overcurrent circuit breaker.
