The NEC does not prohibit the use of a 3 conductor cable instead of a 2
conductor cable. The spare conductor should be capped with a wirenut and
identified on each end as spare. It does not create a hazzard or violate any
codes I am aware of. Inspectors all over the country will approve such an
installation as long as the conductor is rated for the load and the
protection is sized properly.
