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.
