What product?

[oldsparky52]

In a residential setting (actually a community dock), what product is available to provide 30 - 100 ma ground fault protection of a feeder to a panel on a dock? The feeder would be a 120/240 volt 100 amp circuit. I kind of looked years ago for a GF breaker (30 ma) to do this, but it seemed (from my recollection) that an off the shelf breaker is not available.

Standard GFCI breakers for 120/240 volt circuits seem to stop at 50 amps and suggest they not be used over 250' long circuits (IIRC).

Any ideas/suggestions that are not over the top expensive?

Looks expensive. A lot of money for a 120/240 100-amp circuit from the service panel to the panel on the dock.
