RV electrical hookups are either 30 amp or 50 amp. An easy way to tell which amperage your camper uses is that a 30 amp cord has three prongs and a 50 amp has four. Find the RV electrical plug (it looks like a washing machine plug). Its usually retractable and kept in a small marked compartment on the side of the rig.

What is the difference between 30 amps and 50 amps?

And 30 Amps times 120 Volts equals 3,600 Watts. Thats because there are actually two separate 50-amp conductors in a “50-amp” shore power outlet. It probably should be called a 100-amp plug since thats how much amperage is really available.

How many amps can a 50 amp breaker handle?

A 50 Amp split phase 120/240 VAC service should be capable of 50 Amps per leg for a total ampacity of 100 Amps.
