my slip provides 1 50A service. Boat takes 2 30A. Would you get a single 50A cable and split inside the transom, or 2 30A cables and split at the pedestal? If I go the 50A route, what if I transient at a slip that only offers 30A breakers? Which is more common/ versatile? I currently have 2 30A cables with a 50A splitter at the pedestal. All are kinda beat and not connecting together tightly (collars are broken, and the 50A doesn't fit tightly at the box).
