6-1. Selecting Equipment
6-2. How Much Power Does Equipment Require?
1
EXAMPLE 1: If a drill uses 4.5 amperes at 115 volts, calculate its running power
requirement in 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.

AMPERES x VOLTS = WATTS
4.5 A x 115 V = 520 W
The load applied by the drill is 520 watts.
(200 W + 200 W + 200 W) + 520 W = 1120 W
Be sure equipment
has this symbol
and/or wording.

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 6-6).
