Wiring a 50 amp 120v rv service

[Ranger Danger]

Howdy,
You have given us some pictures. Now take a picture on the inlet on the RV. The inlet plug will have special little writing on it will then be your course of action. (NEMA xxa-xxxv) The MEP-802A can supply what you need. It will really depend on the RV itself.

OK, what is the RV? make, model, etc... The internet is fantastic in looking things up.

pictures needed,
inlet
breaker panel in RV

I'm actually not using the RV plug. I am hard wiring from the genny straight to the inside breaker panel in the RV. I would post pics but the RV is in 30" of snow, 2 hours from here. It is a 36' fifth wheel with 3 slideouts made by NU-WA under the name Hitchhiker premier. These pics are not of mine but mine is identical to this one.

Here's an article that should help clear this up as to how a 50amp (and 30amp) RV is wired.

https://www.rvtechmag.com/electrical/chapter3.php

30 amp is 120 volt single pole and 50 amp is 120/240 volt split phase.

That's a good read! Check out the section on RV Breaker panels.

This is the best wiring diagram for an RV 50 amp 120v I could find. Both black wire and red wire are 120v supply. From the genny, each would provide 26 amps when set in the 120/240 setting.
Remember I will be wiring direct from the genny. Not through a plug. The other option is to run one black wire at 52 amps and jump it across to the red wire in the diagram. Set the genny in the 120v setting.

You need to use the input built into the RV. That will determine the setting and connection for the generator.

Howdy,
I did some googling..
It will depend on the options for electric service on the RV. There are option code for a 50 amp 120/240 CS6365 connection, which means you can always adapt down. Then there is 30 amp 120v power connection option.

Your connection (hard wired or not) will be dependent on how your RV is configured.

IMHO, you should invest in a bunch of batteries for a battery bank, and solar panels for running the battery charging and converter.

I would suggest that any other modification should be taken up with your RV dealer.

My unit has the 50 amp option.
I have already done the battery thing. I have 4 100 amp/hour Lithium Iron batteries (Battle Born) and a premium charger.
Solar is out! My property is heavily forested and even in the small clearings that get sun light, I would need a massive amount of panels to get any real solar benefit.
The reason I was considering hard wiring is because of the distance to the genny and the voltage loss that can come from to many connections. I may reconsider this just for convenience.

If you have the #6 wire, you can span a long way with little drop (120v, 50a in,100' = -3.95v = 116v) If you don't have it yet, a 75*c wire in #8 would work too (113.7v).

Thanks to all who have assisted me in this project. The genny will be delivered some time next week. It will then take me a couple of weeks to do the installation. I promise that I will come back with an update at that time. Again, Thanks everyone!! RD

Ok, I got it done. The wiring run is 72' buried 24" down in 1" PVC pipe and 83' overall. I ran 4 6 gauge wires. One each red, black, green and white. I connected the red to L1, black to L3, white to N and green to ground. I set the genny to 120/240. I wired the RV end just like you would a 240/ 50 amp plug. I did not wire it directly to the breaker box but rather to a supply pole where I then ran a 15' 50 amp RV power cord to the RV. I drove a 8' x 5/8" copper ground rod in 7 feet right next to the genny and connected a bare #6 wire from the ground lug to the ground rod. I can now run the A/C, microwave, TV, heater and battery charger all at the same time with no noticeable strain on the genny! HOORAY!!!

MANY Thanks to everybody for your assistance!!

Just a question on ground : you have it going to your trailer but also a grounding rod at generator ?
I’m guessing trailer has no grounding?

You are correct. The trailer is an RV so no ground.
