Square Footage: Living: 1940 sq-ft , +260 sq for small workshop.=6.6 kW
Laundry - 1.5kw
SABC-3kW
Water Heater: , 5.5kW
Range: 8kW Need Name plate, I will use this for Optional Calc.
[Refrigerator: 11.2A, 120V Include with SABC 220.52
Dishwasher: 9.0A, 120V,1.08kW
Microwave/Range Hood combo unit: 1kW
Dryer: 6.24kW
Garage Door Opener: All I could find on the rating was 1/2hp, so per T430.248: 9.8A @ 120V. And per 430.24, 1.25*9.8*120=1470VA
I think this stuff is included in general lighting load
Lighting Load beyond those Required in Article 210:
1 in Kitchen (non-linear rated 204 VA)
3 bathroom ventilation fans @1.17A each, 120V
Additional Fixed Load:
1 whirlpool tub whose motor is rated 7A for 120V, 840VA
HVAC:
Unit 1: Package Gas Furnace and A/C: Min Ckt Ampacity: 17.9A @240V=4.296kW
Unit 2: Split Unit Heat Pump:
Outdoor Unit: Min Ckt Ampacity: 14.1A @240V=3.384kW
Indoor Unit: Min Ckt Ampacity: 33.5A @240V for blower + 8kW auxilliary heat.=8.04kW
You did not specify one or the other units, so I am counting both. total =15.684 kW
With the Artical 220 Parts I-III I get 227A, with Part IV (Optional) I get 160A. Though I didn't include the workspace in the sq-ft calc and am wondering if I should've.
I came up with 149 amps using the optional calc.
