Make sure you use three conductors! Some think the grounding conductor isn't important, but it sure is!
Just nitpicking, but... the ground is not referred to as a conductor. If you buy 14/2 cable, it will have 2 conductors and a ground for a total of three wires.
But I agree, the ground wire is THE MOST IMPORTANT connection you make. It is the one that can/will save your life in the case of an electrical fault.
