Location: western PA | Run a 30 amp entrance with a #10 AWG shore cord. Any interior AC wiring icircuits are run with 12 AWG wiring and a 20 amp breaker, or 14 AWG wiring with a 15 amp breaker. 30 and 20 amp services are commonly found at RV and camping sites. |

Location: western PA | If each of the appliances you've mentioned is powered by 110 voltage, you will not be able to run them all at the same time on a single 10 AWG circuit. If you add the needed amperage of each implement together, the sum will exceed the amperage that your shore cord is capable of maintaining. If you have propane installed and used the electrical circuits only to start the appliances, the gas service will replace much of your electrical loading. An AC unit, combined with other heavy loading such as a microwave, hair drier, space heater, coffee maker or electric water heater, will draw too many amps for a single circuit. Additional moderate loading such as lighting, an electric fridge and media equipment will only add to the load's total. If you want to run many items at once, you will have to consider a second source of energy. |

Location: Richmond, Ky | You're "shore" cord needs to be considerable bigger i.e. 8 gauge for around a 50 amp service, now the problem is not to awful many campgrounds are equipped with the 50 amp service. The majority I've been at are a 30 amp. The ones you visit might and will be different, just plan on that. Sounds like the campground you will be at, and in addition to your feed-in cable are you're biggest restrictions now. You will need to have on hand the adapters to convert to whatever the campground uses. You're only other option is to be sparing in what electricity you use while connected to a 30 amp plug.

Location: North Carolina | I sometimes want more than 20 amps. Example: run the a/c plus coffee maker. Most campgrounds have two circuits at each site. One a 30 amp and a 20 amp. I haven't yet run into a 50 amp service. I installed two 20 amp inlets. The two circuits are only connected together at the ground. Hot & neutral are separate between the two circuits. I then use two shore cords. (with an adapter for the 30 amp service.)

Location: Richmond, Ky | I have a 10/3 wire going to a 30 a. plug that goes to a breaker box that is split that uses breakers on both sides use the piggy back 20a. breakers for more circuits, have never had to turn a breaker off. I just use my demand for elect. sparingly i.e. don't run coffee maker, hot water, micro wave, a/c at all the same time, I do have a variety of adapters that I carry that will allow me to connect to whatever is available at the time and just use what appliances I can at the time. I have been to 1 site that has a 50a. but it is a small camp, not many have these. Worst case is you will trip the 30a/20a breaker at the campground if you get to demanding. |

I don't think it should be used on a 120 volt single phase feed. It's meant to control two phases for 240 volt devices. Just use half height single pole breakers in your trailer.

Location: Richmond, Ky | maybe I got the wrong pic, it's a breaker designed to supply additional 115 vac circuits when all remaining spots are full' it is a "half height" 115v not 220 vac, that might be just a little hard to find a 220 volt in a horse camp ground. |
