Understand Wattage

Power Required

Running Watts

‘Running Watts’ refers to the power required to continuously run an electrical device after it has already started.

Initial Surge

Starting Watts

‘Starting Watts’ refers to the momentary surge of power required to start motor-driven products like a refrigerator. You may need to estimate this by using the following equation if Running & Starting Watts are not known: WATTS=VOLTS x AMPS.
