Sizing Dryers and Ranges, Load Calculations

This video is to help you understand how to size a Dryer and a Range in a single family service calculation.

DRYER

Art. 220.54 States that a dryer must have a minimum demand of 5000 watts or the Nameplate rating which ever is greater.

RANGE

Art. 220.55 States that an electric range must be calculated according to Table 220.55

Note 1 is explained that if you have a range that is over 12kw every 1kw over 12kw must be calculate by 5%.

Example

15kw
-12kw = 3kw

3kw
x.05 = 15%
8000 per 220.55
x1.15 = 9200watts
