Not afraid to appear dumb here, obviously lol. I have 2, 50 amp outlets at the pedestal. My boat has one receptacle for the power cord from the pedestal. Inside the boat I have 100 amp box
.
So there is one, 50 amp service cord coming into the boat. Question is when the central heat an air operates. What does that leave for my,frig, ele. stove, lights tv hot water heater etc. I understand I have not given you make model size an serial number of the above , obviously its an ambiguous question.
Never the less it makes me wonder.

Perhaps my concern should be what, or how much damage Am I causing to my appliances & or electronics? Anyone notice on your dock an unusual replacement of electronics an electrical appliances? Appreciate your thoughts
