We are staying at a campground that has 20A service. Does that take the same dog bone adapter as our electrical outlets here at home? I was going to call the campground but they're closed right now....
Actually, a true 20A plug does have 1 horizontal and 1 vertical prong,.to keep it from being inserted into a 15A outlet. 2 vertical proungs are 15A. I found out when I bought a 50 foot 20A extension cord and found that there no 20A to anything adapters. Ended up making some, cost me as much as the cord did.
