So I still have not hired the electrician yet but I have sorted out what was done to the boat on the past maybe. Like I have said before the boat was US made and then took to Europe
where it stayed for years. I think it originally had 2, 30 amp 110 breakers. So either circuit could be powered of you only had one hookup to shore power
. If you had both then you could throw both breakers get 220 and run the AC units. At some point in the past someone decided they wanted 220 plugs in the boat. So they put in a 50/230 plug
and ran a jumper from one 30 to the other. They also rigged the circuit breakers for the plugs to carry the 220 for the plug
ins in the boat. I think that is how current
is finding it's way to the water
. it only happens when the top CB is used. doesn't do it when the single
110 CB is used. I think they are running 110 thru the old neutral wire in the plugs and that may be hooked up with the grounding system. Sound reasonable?
