Ok if 50 amps is really a total of 100 amp because you have (2) 50 amp legs how do you get only 30 amps with a adapter your not changing breaker size just plug. Does the adapter just use 1 of the 50 amp legs?

Yes, only one of the hot legs on the 50 Amp supply are fed through to the one hot leg on the 30 amp side.

The adapter uses one leg of the 100 amp circuit, so it's capable of delivering 50 amps through the adapter and cord BUT your RV is protected by the 30 amp breaker.

Dear "not true"--the point being that you are supplying 50 amps on one leg from a 50 amp breaker thru your 30 amp cord. I have seen a number of 30 amps cords and plugs severely damaged when folks used then for extended periods at max capacity of 30 amps. Agree, your 30 amp TT breaker does protect from overload but your cord is over amped--curious, would you step-down 50 amps [via dog bones] to a 14 gauge extention cord--hope not......

The amount of mis-information when it comes to 50 amp circuits in threads like this is amazing and nom, I am NOT going to try and set it straight.

Old Scout talks about 30 amp cords being damaged by running near max for extended periods

I have two cords. completly different cords, one 30 one 50 On a 50 amp site I use the 50 amp cord, I do not use a dog bone (RV is 50 amp) on a 30 amp site I use the 30 amp cord and plug into a 30 amp outlet (there is no 50) and yes, the plugs and extension cord outlets have melted I've had to replace them all.. This is because the TT-30 plug/socket is not capable of true 30 amp service in most cases.. I also noticed it is the NEUTRAL side that usually melts.. WHY.. Not pure copper that's why.

On most outlets the neutral is a "Shiny" metal more silvery in color, the HOT lead is copper colored.

Home is where I park it!
