Re: [Amel Yacht Owners] DC cable sizing for larger charger
toggle quoted messageShow quoted text
When I bought a new charger I went with a 60A. The cables from the charger go through the forward starboard corner of the engine room, then under the raised "step" between the Nav station and passageway to the battery compartment. In that area under the "step", they are encased in a very hard material and would be very hard to replace. You would have to look at the specs required for your new charger to see if the existing ones are adequate for the amperage and distance.

I recently replaced my failed Dolhin 30 Amp charger with a Mastervolt 60 Amp charger. I did not upgrade either th AC or DC wiring. All seems to work well. Now I'm considering replacing the 50 Amp charger with a Mastervolt 80 or 100 Amp unit. I think AC input wire size is OK. Amel used the same size wire for both 30 and 50 Amp units. My concern is DC wire size. Not sure but it appears to be 25mm sq. (3 AWG). Again Amel used same size for both 30 and 50 Amp chargers. My question is will this size wire support larger charger? Or will I need upgrade to 35 or 50mm sq.? Has anyone done this upgrade without wiring upgrade?
