So when it comes to electrical my knowledge is minimal at best. I plan to take the camper to deer camp in late November and will be able to plug into a standard 20 amp plug in and need to know how he...
20 amps #12 is just fine for 100 feet. Just because you live in a ranch home and the breakers are in the garage and the kitchen is 80 feet away you will never find an inch of #10 case closed. Oh if the #12 is warm it is working... a good thing!
