Talk to me and I’ll spill the beans… it’s yours…

 

Some stuff can be had at electrical supplies, but the trend will be towards home electrical. High grade can also be had from some pro audio installers (both home and auto). My favorite is welder supply as they tend to use proper copper with high strand (flexibility). You can ask any of these if they have leftovers/drop/remnant if not offered by the foot.

 

That's where ive had good luck in the past, audio car installers. That power werx stuff Bert posted looks promising though.
