Campsite Electrical

Thanks for all the replies, I really wish I had taken Electricity in High School. One additional question that just came to mind.
This time, when dealing with Amperage:
- I am assuming that the circuit breakers are what protect me from drawing too much current
- I also assume that the TT should than have a 30A master breaker that will protect me from trying to draw more than 30A (from all sources inside the trailer)
- If I use a dog bone to connect to a 50A service, there should be no danger as the master breaker will protect me from drawing too much current
- If I use a dog bone to connect to a 15/20A service, there is danger, as I could draw the full current and even try to draw more. In this scenario, there is no protection (from myself) and I could damage equipment, and a Surge Protector will do nothing to help.
Again, are my assumptions correct?
Thanks
Actually, connecting to 15/20 service, everything on your RV is protected within ratings by that 15 or 20 amp breaker. But connected to 50 amp service, your power cord between dogbone and your own main is unprotected for overload conditions, which would have to be from a fault in the cord itself, or connections at either end. Plugs burn up, and their can be overheating of loose or faulty connections at the entrance.
50 amp breaker will catch a short, but there are possible problems other than shorts.
