Watts = Amps x Volts
Running Watts* = Horsepower x 932** (for motors)
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.
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.
CONVERTING AMPS OR HORSEPOWER INTO WATTS

Add a 10% correction factor to your totals to help overcome this uncertainty.
