♦ Connect the cable end in a dry environment.
♦ Install a circuit breaker in the permanent electrical
installation, with a contact opening of at least 3 mm
at each pole.
Protective grounding wire
The protective grounding must have a cross-section equal to or greater than that of the phase conductor.
Residual current circuit breaker
