Residential Wiring Chapter 13 Flashcard

Front

What is required to control a lighting outlet from four locations?

Back

Two three-way switches and two four-way switches.

Front

When reidentifying a white insulated conductor as an ungrounded conductor, what must the identifying mark do?

Back

The identifying mark must completely encircle the conductor.

Front

Can a white insulated conductor be used as a 'hot' conductor in a traditional switch loop if it is reidentified?

Back

No, it cannot be used as a 'hot' conductor in a traditional switch loop even if reidentified.

Front

What percentage of the ampere rating of the switch can motor loads not exceed when controlled by alternating-current general-use snap switches?

Back

Motor loads must not exceed 80% of the ampere rating of the switch at its rated voltage.

Front

Where are four-way switches installed in relation to three-way switches?

Back

Four-way switches are always installed between two three-way switches.

Front

What is the function of a four-way switch in a lighting circuit?

Back

A four-way switch allows control of a lighting outlet from multiple locations.

Front

What is the National Electrical Code (NEC) requirement for reidentifying conductors?

Back

The NEC requires that the identifying mark must completely encircle the conductor.

Front

What is the maximum load for a switch rated for 15 amps when controlling motor loads?

Back

The maximum load is 12 amps (80% of 15 amps).

Front

What type of switch is used to control a light from two locations?

Back

Two three-way switches are used to control a light from two locations.

Front

What is the purpose of a switch loop in residential wiring?

Back

A switch loop allows a light fixture to be controlled by a switch without a neutral wire at the switch location.
