The price of electrical wire has me in tears lately so I was real excited when I went to SamsClub and picked up 4 gauge 20ft jumper cables for $19.<br>I was real excited because on their website it says they are pure copper. It does not say on the packaging, but the cables have stamped copper clad aluminum (CCA).<br><br>So... it is still a decent price at $0.50 a ft for CCA, they are proper thickness. Just remember you have to treat them like they are 5-6 gauge wire instead of 4 gauge.<br><br>Does anyone have any other places or ideas to find cheaper wiring?<br><br><br><br><br>ps so now I don't know what to do with them. I would much rather have pure copper wire for my camper, and I don't know if 20ft long jumper cables with 6 gauge equivalent wire will be able to jump a diesel.
