Backfeed through RV Circuit?
 
I am in the process of installing a 6/3 50A circuit at my home so I can power my RV when it's sitting in the driveway. The RV also has a Onan 5500 LP generator.

My question is, can I do the reverse? When there is a power failure, can I disconnect the main at the panel and backfeed a couple of circuits (gas furnace w/radiators, and/or refrigerator) simply by starting the generator in the RV? Will this work?

You will need a listed interlock or transfer switch to prevent feeding power onto the utility lines.

This could also create what is called a suicide cord with energized male blades on the cord.

How many times are you going to post this. You would need a seperate hookup to go either way so there's no male cord caps energized. Plus you would need an interlock kit which you can't do on a two way run.

Doesn't shutting off the Main accomplish this isolation? Isn't that the basis of the "interlock" they advertise on this site?

andrew79 07-30-2012 01:24 PM

No an interlock makes it so that your generator breaker and your main can never be on at the same time. Therefore its going to be tough to feed your rv from a breaker that can't be turned on. If you run a seperate feed to the rv, Then another run back to the house from the rv generator with an interlock between that breaker and the main you would might make it work although you run the risk of creating a loop from your rv to your house back through the rv feed to your rv generator.

You'll have to face facts. It shouldn't be done. This is the second time I've seen this posted. Your name leads me to believe its the fifth. You just going to keep doing it untill someone says its ok?

To Andrew79:

This is my first day on this forum and asked a simple question. I love how quickly you jump to conclusions.

Since you always seem to dispense some ridicule and sarcasm with your advice, does anyone actually listen to you? They probably hope that someone civil will also respond.

I am the civil one. Be glad someone else didn't get to you first

No, you would need two separate installs. Run a 6/3 and a 10/3 out to the RV location.

Well he was not jumping to conclusions, follow the link below to see what was posted two days ago. No one will know if you are the same person but what you are wanting to do could kill someone if not done right.

A simple IP check would find this out. Unless of course someone is hiding behind a proxy. :whistling2:

Sorry, I never saw that post, but that's essentially my question - posted in a more "in your face" style. I 'll go read that whole thread before I post anything further. Thanks for posting that link to the topic.

Evstarr 07-30-2012 07:05 PM

Just a heads up. That ones not much more polite <whistles>

i'm wondering what would be required at the panel in the house though, you have the interlock which kills the main power and turns on the gen which in turn feeds the rv through the 6/3 and back to the gen in the rv(assuming the rv also has a transfer switch) I get that you can just shut the breaker off but wouldn't that be detrimental to the system if you forgot to, like a dead short basically.

edit:nm it would work more like a double feed. both lines would have power on them.

AllanJ 07-30-2012 07:50 PM

One set of wires cannot perform both of these functions:

1. Feed utility power to the RV (or other load) outside.
2. Feed generator power from outside to the panel.
