7.3.2 Wall sockets and circuit breakers & fuses
Task: Electronic circuit breaker for a certain live wall socket needs to be
located at the electrical panel or cabinet.
-
Connect transmitter to the Schuko wall socket between phase (P) and either
neutral (N) or protective earth (PE) contacts with the
S3TB
cord respective
wires.
-
Choose Near cable mode with receiver. If necessary, the route of the cable can
be traced as shown in paragraph 7.3.1.
-
At the electrical panel it is highly recommended to use the receiver so that the
nose top side groove marked sensitive spot is closest to the fuses, not the nose
tip, as seen in the figures below.
-
First, track all circuit breakers which give a strong signal. It is normal that
several circuit breakers give a signal, as they are parallel connected via their
phase rail.
-
The right circuit breaker usually has a very strong signal and there is a sharp
minimum in the middle, which distinguishes it from other circuit breakers.
-
If the right circuit breaker is turned off, signal level decreases significantly. In
this case the signal can however be detected with
Open wires
mode as well
(see the next example).
-
Signal behaviour and receiver usage are somewhat different with ceramic fuses
with respect to electronic circuit breakers. Therefore it is recommendable to
practise receiver use beforehand with known fuses/breakers.
NOTE! Parallel wall sockets with loads such as heaters or lights will
cause transmitter current spread to other directions than towards the
circuit breaker, which may affect locating the right circuit breaker.
Task: A turned-off electronic circuit breaker or removed fuse base for a
neutral wall socket needs to be located at the electrical panel or cabinet.
-
Connect transmitter to the Schuko wall socket between phase (P) and neutral
(N) contacts with the
S3TB cord respective wires.
-
With receiver choose either Near cable mode (remember to direct the nose top
side groove towards the circuit breakers) or
Open wires
mode (point the tip of
the nose towards the circuit breakers).
-
Above the right circuit breaker there is a strong signal but no minimum. Other
circuit breakers usually have no signal.
