Post Subject: Electrical - galvanic isolator

Our narrowboat is moored in a marina with shoreline connection to each berth - would you suggest I fit a galvanic isolator ?

Post Subject: Electrical - galvanic isolator

No need to if you continue with your "no hull earth" policy (see other question). If you fit a hull earth then a qualified yes. I would rather you fitted a correctly insulated and wired isolation transformer (see the canalworld forums again). If you decide on an GI, at present I would only fit one myself if it complied with the American ABYC standards. As far as I know there are no UK or EU standards specifically for galvanic isolators and questions have been raised over some of those available in the UK (again see the forums).
