Shore power electrical system

Risk of electrical shock.

Do not charge the boat if the RCD (residual current device) is out of function. Disconnect the charging cable and contact Candela.

The shore power system safely distributes power to the high-voltage battery when the boat is connected to shore power.


A. Charging fuse box with RCD

B. Galvanic isolator
C. Charge port (and charging cable)

Galvanic isolator

The protective earth of the shore power is connected to the ground system of the boat through a galvanic isolator, to minimize the risk of ground current and galvanic corrosion.

Charging fuse box and RCD (residual current device)

The charging fuse box contains circuit breakers for over-current protection, and a residual current device (RCD). The RCD detects and prevents potential ground leakage currents that could otherwise result in serious injury and/or fire.

Trip testing the RCD

The RCD (residual current device) is located in the charging fuse box, under the sunbed stowage bag on the starboard side.

  1. Connect the boat to shore power.
  2. In the charging fuse box, identify the RCD.
  3. Push the RCD test button next to the RCD switch. The RCD switch should turn off, indicating that the RCD is functioning properly.
  4. Reset the RCD switch.

Risk of electrical shock.

If the RCD switch does not turn off when pushing the test button, there is an electrical issue. Disconnect the charging cable and contact Candela.
