Dumb question on connecting car battery and roof pump

So i got my car battery and my roof pump im trying to hook together to charge the roof pump. Got the isolator so that the pump doesnt kill the truck batter, check.

Went to Lowes to get the 0 gauge wire to do it and he told me i need DC wire and they only carry AC wire. Im electrical stupid so can someone please tell me....

Is there really a difference in these two wires and would it make a huge difference in this application?

I'm coming in just to have a little fun with you.

So, how do you charge a roof pump? I didn't realize they held a charge.

Apparently the Lowe's guy doesn't know much either. There's 2 common kinds of wire... stranded and solid (not A/C and D/C). Granted, solid wire is used primarily for A/C work in your house and stranded is used in your vickles (D/C), but they can both be used for either, you just need to know which and what and why and where and ... call an electrician for more details.
The gauge determines what it can be used for and how many amps it will carry. Huge difference, no, but you want it to be close on the higher side.
 
Vehicle wire is much more flexible to run through a vehicle. You can get it at a stereo store. You should be fine with 8 gauge depending how far you are running. 4 gauge tops. 0 gauge is overkill.

That guy who told you to get the dc wire is full of crap. I bet he tried to sell you a left handed shovel too.

The gauge of wire will vary based on the overall length but 6 or 8 gauge would be plenty big enough to maintain a charge on the battery.
