I understand 220.60 to say, add 125% of whichever motor load is larger to your noncoincident load. say your condenser fan is 3.5 amps,
3.5 x 1.25 =4.375 added to your 220.60 calculation. 120 x 4.375= 525 va.

Good Morning Why is the AC/Heat pump the largest motor??? Im a bit confused...

[ericpolk]

if you had a gas heater and a AC that is 5520W do you still hit the AC with 125% Largest Motor?
