under the floor?

I'm am upgrading the load center and running a new wire for a microwave on a 66 Overlander. Is it OK to run the wire under the floor as opposed to pulling interior panels? I do have 12-2 UF with gound and plan to use grommets where needed.

Thanks TomE

If you are talking about inside the belly pan, I guess you could. Dropping the belly pan is a big job. Are you sure you can't somehow utilize an existing circuit? As long as you are running only one appliance at a time you should be fine. If you have the original water heater you might want to run a line for a new electric/propane heater and have it there if and when you need to replace the unit you have know.

If I were running it under the bellypan (not sure if that is what you mean) I would put it in inexpensive plastic conduit with sweeps on either end to turn up into the coach. However, I would think you could find a way to run it inside in the cabinets and avoid the problems of that system. Also, the microwave, even though a fairly large load of 1000 to 1200 watts, is not used very long or much, and I would think you could just use it on a regular circuit. Don't run the coffee pot on brew on the same circuit and you will probably be fine.

The whole unit was gutted to reflace the rear floor. I replace the axles and all the wiring under the floor and used POR15 on the whole frame. I just thought it would be way easier to run the wire under the floor while everything is open.

The original load center had a 30A main and a tandem 20 for the whole trailer. I am putting a 4 space box in with a 30A main, a 20 for the A/C that I added, a 20A for the microwave, and a tandem 20 for the old circuits. I just want to finish the wiring and leak test before I put the vinyl down and start putting things back in their place.

I don't see any reason not to, as long as you protect against abrasion.

Good question I am putting a 50 amp service in my trailer. I have to run 6/2 romex from the inlet to the distribution box. The wire is too big to fit in the wall so I am going to take it downtown. We shall see.....
