CONVERTING AMPS OR HORSEPOWER INTO WATTS
If necessary, uses these formulas:
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 requirements, 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.

WATTS
Motor A 2,600 850
Motor B 1,300 600
Motor C 1,000 750
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.
