WATTAGE CALCULATIONS
STARTING WATTAGE REQUIREMENTS | 2. To determine the approximate starting wattage |
| requirement for most appliances and tools with |
1. Some appliances and tools will list on the motor name | inductive type motors, multiply the wattage that was |
plate the starting and running voltage and amperage | calculated by 2 to 4 times to assure adequate generator |
requirements. Use the following formula to convert | capacity. If the nameplate information is not available |
voltage and amperage to wattage: | use the values on the following chart as a guide. |
Volts X Amp = Watts | 3. Remember that the starting and running wattage for |
120 volts x 10 amps = 1200 watts | resistive loads are the same. (Example: a 100 watt light |
bulb requires only 100 watts to start.) Most resistive | |
| loads will be listed in wattage. |
