I always use old ATX power supplies. I've not had any problems with melting the outer insulation. But thicker, as you said, not 22AWG. You could try Sayal. Princess Auto has only 14ga. https://www.princessauto.com/en/24-gauge-green-plant-wire-assorted/product/P... Here's some 24 gauge green plant wire, very cheap, maybe ok for electrical applications, you'd need to check, 100ft, $2 Sometimes I can find an old non PCB floor fan, which has long runs of wires. They are also not as thin as 22 gauge. On Thu, 4 Dec 2025 at 17:32, William Park via Talk <talk@lists.gtalug.org> wrote:

Anyone know where to get cheap/free 22AWG solid wires? This is for breadboards, headers on embedded boards, short test leads, etc. It would be nice if they come color coded and bundled, but singles are okay.

FYI, this is where I get my supply of cheap/free wires:

1. 18AWG -- Old ATX power supply has lots of color coded 18AWG stranded wires. *Con*: Their plastics insulation melts too easily compared to other wires that you'd buy separately. 2. 24AWG -- Old network cable has 4 pairs of 24AWG solid/stranded wires, nicely bundled. 3. 24AWG -- Old phone cable has 2,4,6 solid wires, nicely bundled. 24AWG (I think).
