What type wire to use from transfer switch to outdoor outlet

Posted by brjl (My Page) on

I have installed a Connecticut Electric transfer switch for my generator (7500 watt) to my breaker panel and now I want to run wire from the switch 60 feet inside the house and hook up to an outlet (30 amp) that will be attached to an exterier wall of the house. I have purchase a rain tight outlet box, the only thing I need to do is run the wire into the back of it from the basement.
The question is, I purchased 10/3 NM-B with ground wire, the wire has a white, black, red, and un-cased ground. Would this be the correct wire to use? I had the impression that I needed 10/4 wire, with the ground wire cased,(green) but the Home Depot person stated that since this is an interior installation, that the 10/3 is what I need. Is the 10/3 wire correct? The transfer swich has a red, black, white and green wire to hook to.

Thanks for any help.

That is exactly what you need, you're good to go.

Be sure to seal the back of the box to the house very well. Some people will argue that the back of that box is considered "outside" and romex shouldn't be used there lol.

Are you really intending to backfeed an OUTLET, or do you actually have a proper inlet for your application?

Sorry, I believe the box on the outside of the house is an inlet.

Anyway, thanks very much for the information, great site.

There's no prohibition on NM (Romex) being used outside. Perhaps you mean "wet locations".

Seal the exterior box around the top and sides to the wall and you no longer have a wet location.

Leave the bottom joint open for condensation escape.
