Caution: Leakage current varies depending on the capacity of the motor to be connected,
cable length and surrounding environment. Therefore, when protective
measures from the leakage are taken, measure the leakage current at the
locations where the leakage breaker is installed.
Regarding the leakage breaker, it is necessary to have a clear purpose for
selection such as a fire protection or protection of human body.
