Recently boaters have been coming across docks fitted with ground fault circuit breakers on their shore power receptacles. This is in accordance with the latest edition of the National Electrical Code and applies to all new construction. Eventually, as docks get rebuilt, all docks will be wired to this standard. Unfortunately for some boaters their boats are having a hard time using these receptacles because they trip immediately on switching on the power. This article is an attempt to explain what this is all about and what can be done about it.
