Setting up shore power
I just finished today, installing a 50 amp outlet 62 feet with four gauge THHN. Man was it tough to go through the basement to the side of the house. The ground wire goes from the receptacle to the ground lug on the box to the main panel. You’re going to need a bigger break if if you want to power all those outlets at the same time. 20amp 30amp 50amp = 100amp. 162 feet is so far maybe 2awg is better. I spent $530 for all the material. Not very hard to wire 4 wires to the main panel.

Not required.
Also remember that the 30 and 20 are 120v and will be on opposite legs. So theoretically max current draw on any leg would be 50+30 on one leg and 50+20 on the other. With the box Wired and protected with 70 amp it will be fine.
My 50 amp RV never draws over 30 amps on any leg even with both AC units, refrigerator, water heater and converter running. In fact I run it on a 14-30R, 30 amp 240 4-wire dryer outlet with a proper adapter at home when loading it for a trip. (You can’t do that on an obsolete 10-30R, 3 wire dryer outlet because it doesn’t have a ground where a 4-wire does)Jerry & Linda

The breakers I was talking about are the breakers at the beginning of the 160 foot line. They will need to be sized to carry the max load from each outlet as if they were drawing their full rated power. Even if your 50 amp coach never exceeds 30 amps, there are some coaches (Class As or units with three A/C units) that can utilize all 50 amps available from a 50 amp Shore Connection.

Actually the feeder breaker needs to be sized to protect the feeder wire.
NEC Code for RV parks is interesting. If the RV site is expected to be dedicated to a single RV, with a multi-receptacle supply enclosure, the load you count to determine the feeder size is the highest rated receptacle in the enclosure. However if the site is expected to serve two recreational vehicles the load you use to calculate the service is the two highest rated receptacles in the enclosure.
So on a single RV site with a multi-receptacle enclosure with 50+30+20, a 70:amp feeder wire and breaker is fine since with a 50:amp RV the 30 amp would not be used at the same time.Last edited by Jerryr; 07-30-2021 at 08:40 AM.
