Since you have such short runs, you might want to think about making your own cable. Using two individual runs of solid core 10 gauge, simply twist them together i.e. make a twisted pair out of them. The twists don't have to be consistently spaced, but should be done at a rate of appr 3 - 4 turns per foot. This will be used for the hot and the neutral. The ground wire can be run individually outside of the twisted pair.
One suggestion here. If your runs are going to be 20 foot, start off with 25 - 28 foot of wire or so. You WILL lose length as the wire is twisted. For your own sanity, it is best to cut individual runs and work with the shortest lengths possible. That is, don't try and twist 100 ft of cabling together and then cut to length. Having another person to hold the far end and rotate it accordingly can make things go MUCH quicker and easier. Sean
