The electrical engineers that come up with the codes always over protect.
40 years in IBEW and IAM. Everything from 500 thousand volt transmission protection to
lowly 12 thousand volt distribution circuits and God forbid... House wiring... a 15 amp running current @ 120 Vac on a #14 wiring circuit protected by a 20 amp beaker is not going to cause any electrical problems.
Code? No.

No way in hell I'd give that advice. A malfunction in the compressor and the wire melts down and so does the house.
Do it the way it's supposed to be done.
