Optional Method Calc - 04/22/05 08:04 PM

Hi,

What is the optional method for a load calc? Can this be used on a sub panel?

I used an online calculator and got the following:

General Light and Receptacle Load

1308sqft x 3VA = 3924VA

________________________________________

Small Appliance Circuits Load

2 x 1500VA = 3000VA

________________________________________

Laundry Branch Circuit(s) Load

1 x 1500VA = 1500VA

________________________________________

Total General Load Less Demand

sum of above less T220.11 demand

sum of above = 8424VA

first 3000 at 100 % = 3000

next 117,000 at 35% = 1898

remainder at 25% = 0

sum less demand = 4898VA

________________________________________

Fastened In Place Appliances Load

Disposal = 1176VA

Garage Door = 1000VA

Dish Washer = 1600VA

Attic Fan = 700VA

Microwave = 975VA

sum less 75% demand = 4088VA

________________________________________

Clothes Dryer Circuit(s)Load

Total dryer circuit(s) load = 0VA

________________________________________

Cooking Appliance(s) Load

Range 9.5kVA

T220.19 Column A = 8kVA

T220.19 Column B = 0kVA

T220.19 Column C = 0kVA

Total calc.d range load = 8kVA

________________________________________

Heating or Air-Conditioning Load

Air Conditioner = 4240VA

________________________________________

Largest Motor Load

25% of largest motor = 1000VA

________________________________________

Total Computed Load

22226 Volt-Amps

________________________________________

Computed Amperage

22226 divided by 240 = 93Amps

-------------------------------------

Is there anyway to get this down so I could connect a dryer to it?

Thanks

Bradley
