electric circuits in water

[ExileMoon]

Under normal circumstances, the yacht electric circuits are in a safe state.

But if the boat capsized, and internal water, had dried safety circuit can be soaked in seawater. This time it will have leakage phenomenon.

Things such as power outlets seem difficult to achieve good protection.

Yacht design and construction may be employed that way to avoid this dangerous?

 

[CDK]

You are correct! For AC wiring on boats there is protective ground and residual current detecting devices, but for the DC circuitry there is no protection feasible.

A capsized boat will suffer extensive damage starting at the battery poles and following all electrical paths connected to them. By the time the boat has been recovered and dried, electrolysis has dissolved so much copper that the only solution is complete replacement of all wiring.

A capsized boat and a swamped boat are different things.

 

[Jim Caldwell]

Shouldn't a battery switch set to OFF solve the wiring problem past the switch?

 

[gonzo]

No, because specially salt water is an electrolyte. That means it conducts electricity and will bypass the switch.
