11-4. How Much Power Does Equipment Require?
S-0623
1 Resistive Load
A light bulb is a resistive load and
requires a constant amount of power.
2
Non-Resistive Load
Equipment with a motor is a non-re-
sistive load and requires approxi-
mately six times more power while
starting the motor than when running
(see Section 11-8).

Rating Data
Rating shows volts and amperes, or
watts required to run equipment.
Amperes x Volts = Watts
Example 1: If a drill uses 4.5 am-
peres at 115 volts, calculate its run-
ning power requirement in watts.
4.5 A x 115 V = 520 W
The load applied by the drill is 520
watts.
Example 2: If three 200 watt flood
lamps are used with the drill from Ex-
ample 1, add the individual loads to
calculate total load.
(3 x 200W) + 520 W = 1120 W
The total load applied by the three
flood lamps and drill is 1120 watts.
