1 Resistive Load

A light bulb is a resistive load and requires a constant amount of pow- er.

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 run- ning (see Section 9-8).

3 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 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.

(200 W + 200 W + 200 W) + 520 W = 1120 W

The total load applied by the three flood lamps and drill is 1120 watts.
