I want to install a receptacle right below my garage box, but nobody sells 10-3 romex by the foot. My only other option is to buy a 25-foot roll. I have called some electrical places around here and nobody is friendly enough to let me look through their scraps.
LowesDepot sell 10-2, and I'm beginning to consider just using that and bonding neutral and ground at the receptacle. On the other hand, I could run SJOOW cable, of which I have 30 feet, but technically you aren't supposed to run that in the wall.
