Chapter 5: Conductor Identification, Switch Control of Lighting Circuits, Bonding and Grounding of Wiring Devices, and Induction Heating

What switch type and rating is required to control five 300-watt tungsten filament lamps on a 120-volt circuit?

12.5-Ampere Rated

What type of switch is installed to control a luminaire from two different control points?

3-way switch

What section(s) of the Code emphasizes the fact that all circuiting must be done so as to avoid the damaging effects of induction heating?

300.35, 300.3(B), and 300.20(A)

How are lighting switches rated?

According to their ampere rating at the voltage applied. 404.14(A)-(F)

Is it always necessary to attach the bare equipment grounding conductor of a nonmetallic-sheathed cable to the green hexagon-shaped grounding screw on a receptacle?

No

When two nonmetallic-sheathed cables enter a box, is it permitted to bring both of the bare equipment grounding conductors directly to the grounding terminal of a receptacle, using the terminal as a splice point (i.e. "double-lugging")?

No

Does the Code permit the ampacity of the switch legs to be less than the ampere rating of the branch circuit?

No, 210.18

Does the Code permit connecting receptacles to a 20-ampere branch circuit using short lengths of 14 AWG conductors as the pigtail between the receptacle terminals and the 12 AWG branch-circuit conductors?

No, 210.24

Do receptacles that have back-wired push-in terminals accept 12 AWG conductors?

No, manufacturers design them for use only with solid 14 AWG copper conductors.

A T-rated switch may be used to its what current capacity when controlling an incandescent lighting load?

Rated current capacity.

To control a lighting load from one control point, what type of switch would be used?

Single-pole Switch

Define an equipment grounding conductor.

The conductive path(s) that provides a ground-fault current path and connects normally non-current-carrying metal parts of equipment together and to the system grounded conductor to the grounding electrode conductor, or both.

When connecting 4-way switches, care must be taken to connect the travelers which terminals?

The proper pair of terminals

When metal toggle faceplates are used with nonmetallic boxes, the faceplate must be grounded according to 404.9(B). How it this accomplished?

Through the No. 6-32 screws which secure the faceplate.

A 3-way switch is a type of lighting switch? True of False

True

A 4-way switch is a type of lighting switch? True of False

True

A double-pole switch is a type of lighting switch? True or False

True

A single-pole switch is a type of lighting switch? True or False

True

How many switches are needed to control a luminaire from two different control points?

Two

When connecting single-pole, 3-way, and 4-way switches, they must be wired so that all switching is done in which circuit conductor?

Ungrounded 404.2(B)

Single-pole switches are always connected which wire?

Ungrounded or "hot" wire

The identified grounding circuit conductor must be which color(s)?

White or Gray
