where do you source your power wire

I'm with Jon. Went to a local electrical contractor, told them what we are up to, and asked for red and black stranded 14 ga and 12 ga, and got a full spool (500') of each donated.

I've found that my new team was somewhat clueless as to how easy it is and how willing folks are to donate to a robotics team, once they hear a bit about the team. It usually goes over a bit better than the marching band wanting to go to Florida for spring break and looking for money.

Since I came to the team, we have donations of goods/services including the wire, a desktop CAD computer, a media laptop, some Lexan, limited printing/laminating services, and oh, yeah, from a primary sponsor, lots of aluminum and laser cutting of that aluminum and custom bending fabrication services -- all for free.

We use zip cord (black and red wires molded together) for most of our wiring. Powerwerx, MCM electronics, and McMaster all sell it, but MCM is usually the cheapest.

MTW wire. Automation direct has it. Be careful not to get thhn/mtw. It is less flexible. Powerex. Monoprice has black/red bonded together. Certain appeal, but I don't have personal experience with it.

I second Automation Direct. I buy MTW from them in semi truck sized quantity.

Mcmaster has a good selection of MTW/TEW too, that's usually where I order our 22 and 20 from.

We use MCM for red/black zip cord in various sizes. Check it out here...
