where to buy cable .
What exactly are you going to use this for? I have some cables with multiple wires inside. If you were local, you could have what you needed for free.
You mean like SO or SOJ extension cord ?
You can get 14/2 14/3, 12/2 12/3 ( AWG of the wire, number of wires in the cord ) in SO or SOJ, which is a thick rubber coated exterior that is gas and oil resistant.

SO & SOJ I think are 90* rated wire, so it is not 105* automotive wire. best to go 1 size up if you are close to the AMP rating.
You can get cord in 14/6 and I think 14/8 but this starts to get expensive, and you cannot generally find it at Home Depot or the likes, you will be at an electrical supply house ( or you might find a place online that sells it, but cost per foot & shipping could be a killer, depending on the length ), and this usually has a higher minimum length ( ~ 50' ), where the 14/2 to 12/3 cord you can get by the foot at HD.
