The Delta manual shows that a 5 HP motor can draw up to 28 amperes.

The motor in my central A/C unit draws 30 amps once it's running, but
needs 123 amps (at 240V!) for a few seconds to get started.

So yeah, go with the manufacter's recommendation, not pure math.
You are so right. When I mentioned 28 amperes, I intended that to mean the
current that flows after the motor gets started.
