I got the four wire bundle covered in white vinyl, 100' of it on a spool, from Radio Shack. It is quicker, close by, and it is what I need, so I don't mind spending the few dollars extra it costs. Shipping would be how much...?
.... but isn't that wire only 20 or 22 gauge ?
For my main buss wire, I stripped the insulation off of a run of 14 gauge house wire netting me a white and a black wire. For the drop feeds, I used 18 gauge lamp cord ! Again, used white and black lamp cord - just split the two wires into singles.
