Good data point. Thanks.
The LRA (locked rotor amps) on my 1.5T are 47.
I do not know why I can start it on a fast blow 15A breaker.
The install instructions demand a 20A HACR (slow blow HVAC) breaker.
Maybe the start kit helps?
What would really help is a 'slow start kit'.
Hard start kits don't reduce LRA, they just reduce the time for amps to
drop.
The 5-2-1 kits are considered the superior hard starts, but slow start
makes it ramp up like an inverter drive.
