- 1992 Tollycraft 44 CPMY
I was told my new-to-me 1992 Tollycraft 44 is equipped with a "2 50A 120V" shore power system and that it's a standard that was not used long and never caught on. My boat is in storage a long way from home so I can't look at it right now.
Are the two 120V inputs tied together on the boat side? It seems like everything was powered with only one connected when I looked at the boat. Guessing there's a switch to connect the two inputs when only using one inlet and a way to disconnect them when using both inlets. Can anyone confirm that that's the normal way they are wired?
If the two inlets can be disconnected from each other, I think it would be possible to connect the boat to a 240V 50 amp outlet, but my gut says the neutral wire in the cable and the dock wiring could potentially carry 100 amps so that would be a no no. Is there an adapter for such a connection? Any thoughts on this?
My guess is that I could connect to a 50A 240 volt outlet, but I could only make use of one phase (120V) of the 240V and I'd be limited to 50 amps at 120V on the boat. Assuming I have two cords, I could also connect to 2 30A 120 outlets and get 60 amps total power.
