What is an earth switch (main circuit breaker)?

An earth switch completely shuts off all power to the boat. The name earth switch is used because the switch is usually on the earth side (minus side) of the electrical system. There are quite a few professional names for the plus and the minus:

  • Plus = positive = red = 31
  • Minus = negative = black = 30

The best-known coding in electrical systems is the “Bosch” code. Other names used for an earth switch are e.g. main switch, battery switch and main circuit breaker.
