Exam 13: Switching Circuit Installation

When installing a receptacle so that one half is controlled by a switch and the other half is "hot" all the time, the switch-controlled half should be located on the ____________________ of the receptacle.

Switch loops are not permitted in three-way switch circuits.

Explain why the top half of a split-wired receptacle is "hot" all the time and the switch-controlled half is on the bottom.

Like single-pole toggle switches, single-pole dimmer switches always come from the factory with screw terminals.

Explain what must be done to a receptacle so that it may be split-wired with half of it "hot" and the other half switch-controlled.

Explain why one dimmer switch and one regular three-way switch are used in three-way circuits instead of two three-way dimmer switches.Assume the use of non-digital dimmers.

A double-pole switch can be used to control two 120-volt circuits.

Three-way switches are always installed in __________.

Switches installed in metal boxes are considered grounded as long as metal screws are used to mount the switch's metal strap to a metal box that has an equipment-grounding wire connected to it.

To control a lighting outlet from four locations, a circuit requires __________.

A permanent black marker can be used to reidentify a white insulated conductor as a "hot" ungrounded conductor in a cable.

When using three-wire Type NM cable the white insulated wire is sometimes used as a traveler conductor for three-way and four-way switching and is required to be reidentified as an ungrounded conductor.

When installing a ceiling-suspended paddle fan with a lighting kit, and you want to have separate control of the fan and light, a __________ must be run from the switching location to the paddle fan location.

When wiring a house using conduit, the NEC permits a white insulated conductor to be used as a "hot" conductor in a switch loop as long as it is reidentified as such.

The number of conductors required to be installed between three-way and four-way switches is ____________________.

Dimmer switches are available in single-pole, three-way, and four-way models.

Like a four-way switch, a double-pole switch has four terminal screws and the toggle has "On" and "Off" written on it.

A ________ is a device that controls the flow of electricity on a circuit for a certain amount of time.

Explain how a traditional switch loop for a single-pole switch is wired using Type NM cable.

When reidentifying a white insulated conductor as a "hot" ungrounded conductor, the identifying mark must completely encircle the conductor.
