Teardrops n Tiny Travel Trailers

I have some leftover #4 URD aluminum wire from running electric out to my shop from house. Would this wire work as the wire for grounding to the frame of aluminum trailer for DC and for AC?

I also have some copper 8/3 NM-B leftover from when I built my house 20 years ago. Would that wire work if the aluminum URD doesn't? Just trying to use what I already have to save a few bucks for other fun stuff for the build.

Thanks,
Harry

Harry,
I think I would use copper wire with noalox compound to avoid corrosion. Here is a link to Home Depot, but its available anywhere they sell electrical supplies.

Aluminum wire is kind of frowned on in building except the utility will bring it in on a service. Copper is more reliable .

Good luck,
Dan

I had a problem early on and ended up with a hot skin. My solution was to, since every thing had a wired ground, was to remove all ground wires to the frame. It would have been a problem eventually.
