12-4. 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 12-8).

Rating Data
Rating shows volts and amperes, or
watts required to run equipment.

EXAMPLE 1:
If a drill uses 4.5 amperes at 115 volts, calculate its running 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 Example 1,
add the individual loads to calculate total load.
The total load applied by the three flood lamps and drill is 1120 watts.
(200 W + 200 W + 200 W) + 520 W = 1120 W
AMPERES x VOLTS = WATTS
