Going to my son's and he has had a 50 amp plug put in for us. I am a little concerned about whether he has attached it to a 220 line or 110. The breaker has two 50 switches. Can't afford to fry my 5th...
The 50 amp connector has two 120 volt sides, each rated 50 amps. They are on opposing legs and will measure 240 volts line to line. The top and bottom pins are ground and neutral. The sides each measure 120 volts to either the neutral or ground and 240 from one side to the other. This video gives an excellent explanation of the connection, both 30 and 50 amp. https://www.youtube.com/watch?v=GoOR2AJGjOI Russ
