Bought a used 600w xantrax inverter for 50 bucks. It has a standard househouse type GFI plug on the side instead of hardwire terminals. I'm trying to keep from just gerry rigging the electrical in my brand new trailer. I've seen a ton of people simply buy a 3 prong replacement plug and hardwire to romex and call it a day. Not sure how acceptable that really is, but I see it done. What if I brought in romex to a small junction box and tied in to a 120v male pigtail and run the pigtail to the GFI on the inverter? The opposite end of the romex will go to a 25ft run to the transfer switch wired to the electric panel and the branch circuit I plan to power.

Thanks
 
Welcome to RVF, @Monster1.

Other than the flexibility of the “pigtail,” I don’t see any significant difference between the two approaches. Since I don’t think you will be connecting/disconnecting the inverter frequently, a plug properly wired to the Romex should be fine. And, it would eliminate an extra set of connections when using the junction box approach.

Thanks. I guess I'll go a step further and use armored cable instead of romex. So that I don't have to drill any unnecessary holes, I'm using the battery switch cable run. It goes from the forward storage compartment, routes on the front cap wall and comes out near the battery boxes. There would be about 2ft of the cable being unprotected as it passes back up under the trailer to the power distribution center. I think armored cable is a better option.
