•
Make sure to connect the clamp sensor to the secondary side of
the breaker. The secondary side of the breaker is protected by
the breaker even if a short-circuit occurs. Do not measure on the
primary side as it has a large current capacity, and significant
damage is caused when a short-circuit occurs.
