CONVERTING AMPS OR
HORSEPOWER INTO WATTS
Watts = Amps x Volts
Running Watts* = Horsepower x 932** (for motors)
Remember, this worksheet lists average power requirements a particular manufacturer's
device may use more or less than the listed wattage.
• Add a 10% correction factor to your totals to help overcome this uncertainty.
If your customer plans to operate devices that use electric motors, list both the starting and
running requirements of each.
• Starting requirements of some devices maybe significantly higher than their running
requirements. This higher demand must be considered when estimating your power needs.
Some small, universal motors — which do not draw a heavy starting load (drills, small saws,
blenders, etc.) — require very little extra current for starting.
When listing items that use motors, take them in the order of highest-to-lowest starting require-
ments, as shown in the example below. Motor A, for instance, has a starting requirement of 2,600
watts, so it's listed first, followed by Motor B at 1,300 watts, and Motor C at 1,000 watts.
NO ELECTRIC MOTORS
If your list does not include any devices that use electric motors, simply add the power (running)
requirements of all the items on your list to obtain the maximum power needed.
For example, if you intend to use only an electric skillet, a 100-watt light and a heating pad (as
shown below), the maximum power requirement would be 1,655 watts. In this case, a generator
like the EF2600, that can produce 2,300 watts rated output, is recommended.
If necessary, use these formulas:
