There are no empty circuit breakers. It was originally set up for a 30 amp and 50 amp rv hook up. They are both being used. When I get home I will post what brand of box it is. Thanks
Thanks everyone for the great posts.
I have a 30 amp circuit breaker in my main electric panel that I want to tap into, but only run 15 amp receptacles off of it. Is there a safe way to do this. My only other circuit breaker is 50 amp.
