I figure this string might be good for yet another posting or two.

At the simplest level, the primary function of the branch circuit breaker is to protect the downstream wiring. In order to do so, the wire must have equal or greater capacity compared to the circuit breaker.

So, the questions are:
1) Will the #14 wire be adequate for the purpose Randy has intended? Absolutely, but . . .
2) Will the #14 wire be adequately protected by a 20 amp CB, according to the NEC? Absolutely not.

It's all about protecting the wiring, not matching the wire as closely as possible to a small load. That's why we can't wire lighting circuits with 18 gage wire.
