RESIDENTIAL ELECTRICAL LOAD CALCULATION <br /> Project Address: 2803 Medora Way, Everett WA 98201 <br /> Method for determining the electrical load and sizing of the electrical service: <br /> NEC Article 220 Part IV "Optional Feeder and Service Load Calculations" <br /> NEC 220.82(B) General Loads <br /> General lighting and general-use receptacles 1630 ft2 x 3 VA = 4890 volt-amperes <br /> Small Appliance Branch Circuits - 1500 VA each = 3000 volt-amperes <br /> Laundry Branch Circuit - 1500 VA = 1500 volt amperes <br /> Dishwasher = 1450 volt amperes <br /> Disposal = 1140 volt amperes <br /> Microwave = 1800 volt amperes <br /> Refrigerator = 780 volt amperes <br /> Range = 8400 volt amperes <br /> Oven = 3000 volt amperes <br /> Dryer = 6240 volt amperes <br /> Water Heater = 4500 volt amperes <br /> Sub Total A (Add all loads above) = 36700 volt amperes <br /> The first 10k VA is calculated at 100% - NEC 220.82(B) <br /> The remaining VA are calculated at 40% - NEC 220.82(B) <br /> Total A: Sub Total A 36,700 - 10k = 26,700 x .40 = 10,680 + 10k = 20,680 volt amperes <br /> NEC 220.82(C) Heating and Air-Conditioning Load <br /> 65% of the nameplate rating of electric space heating if<4 separately controlled units <br /> Electric space heating 15186 VA x .65 = 9870.9 volt-amperes <br /> Air-conditioning = N/A <br /> Heat pump = N/A <br /> Total B: Largest Heating and Air Conditioning Load = 9870.9 volt amperes <br /> EVSE (Electric Vehicle Supply Equipment) 40 A x 240 V = 9600 volt amperes <br /> CALCULATED TOTAL SERVICE LOAD: <br /> General Loads 20,680 <br /> + Heating/AC Loads 9870.9 <br /> + EVSE Load 9600 <br /> _/ 240 volts = 167.3 A <br /> Existing Service at 2803 Medora Way = 200 A <br />
