240 v shore power.

at marina that has 50 amp power pedestal with 2 straight 1 twist female cord connector. my 240v 50amp cord has 2 twist and 1 straight. tried an adapter but still can not get power to boat. does the Mainship require 240v at dock pedestal? may be only 120 at pedestal. thanks.

2 straight 1 twisted sounds like 30 amp single phase (120 volts only).

Post a picture of the power pedestal receptacle and maybe your boat's power inlet(s).

Could be 120V 50A. There are some out there. I think Marinco or Hubbel websites have diagrams of the prongs.

Sounds like 50A/125V.

Diagrams here:

Dockhand plugged my 30A 120 into 30A 250 - Cruisers & Sailing Forums

Could be an adapter could work for at least partial power... unless there's an isolation transformer on the boat...

Wow! That was an interesting story. A marina wired 30A 240vac. Someone messed up big time.
