After looking at the lightforce stubby light, and knowing what it cost me to put my mangetic based Hella worklight together, I figure I could probably sell a few and bring the cruiser fund into the positive.

Does anyone know where I could find a quality coiled cord that has 3 12 gauge wires? Thanks.

I think you are talking about "retractile" cord. Right?

Thanks for the lead Christo!
The mcmaster-carr part number for 12/3 retractile cord is 5821K34 at $297 for a 4' retracted length 20' extended length it might not be the best choice of suppliers.
I would contact a local electrical supply house, look for somebody who handles Beldon wire. Knowing that you are looking for retractile cord will help.

After realizing that I don't need anywhere near 12 guage for the load these wires will be carrying, I did some research and 18 guage should be sufficient. Much more reasonable at $33 for the 4'/20' length. Still a bit above what I was expecting/hoping.

Thanks for the education on the terminology.

18ga sounds a bit light? (no pun intended) how many watts are you pulling through that 20'? 18ga at 12V can have quite a significant voltage drop by the time it gets to the end. You are talking about a 40' long circuit for the power to travel.

At 18ga you will be limited to 3-4 amps continuous, not ideal for a work light.

If you can find a way to bump it up to 12ga you'll be good for ~12 amps.

Both of these take in to account that the wire is in free air, not the case for three conductors in insulation.

Here is a reference chart that should help. Since you are in collage and probably have nothing to lose I won't warn you about the liability issues of building electrical equipment. Just buy all UL certified products and remember overkill isn't always a bad thing. My rule of thumb is to design for 120% of the expected load.

If you buy that stuff from mcmaster you'll get screwed on price. They are super expensive. Look for another supplier and I'll be you save about 50%.

They might be expensive but they have some of the best stock availability and super shipping. I can order up to 5pm at the shop, have it then next day and only pay ground shipping rates. Never had them backorder a single item on my, doesn't matter what obscure thing I order.

They are great for that. I use them a lot for prototyping or when trying out blue sky ideas. For production qtys you need t find a more cost effective source.
