4.6.4 WATTAGE CHART
The chart below contains general wattage information, and is intended to be used as a guide only.
For some electrical, and electronic appliances, you can determine the power needed by looking at the
data tag supplied by the manufacturer.
Most products and all electrical motors should have a data tag attached to their bodies that give volts and
amps and may contain wattage information.
To determine the wattage, use this formulae:
Amps x Volts = watts
(See wattage chart)
