Question 1

The term ____ means not connected to ground or a conductive body that extends the ground connection.
A)neutral conductor
B)ungrounded
C)neutral point
D)white conductor

Accepted Answer

The term "ungrounded" refers to a state where an electrical component or circuit is not connected to the ground or to a conductive body that extends the ground connection. This means it does not have a direct path to the earth to dissipate excess electrical charge.

Question 2

When concealed raceways are drawn on plans, they usually are shown as ____.
A)curved lines
B)straight lines
C)circles
D)right angles

Accepted Answer

A

Question 3

____ are not usually permitted on the hinged side of the door but are required to be located on the strike side.
A)Outlets
B)Switches
C)Circuits
D)Floats

Accepted Answer

Switches are not usually permitted on the hinged side of a door because they need to be easily accessible when the door is open. Placing them on the strike side ensures they can be reached without obstruction.

Question 4

A dashed line with an "S" designates a(n)____.
A)underfloor signal raceway
B)sturdy raceway system
C)solid raceway
D)signal raceway

Accepted Answer

An underfloor signal raceway is designated by a dashed line with an "S".

Question 7

A switch symbol without a number beneath the horizontal line means that a ____ switch should be installed.
A)single-pole
B)float
C)three-way
D)four-way

Accepted Answer

A switch symbol without a number beneath the horizontal line typically represents a single-pole switch, which is the most common type of switch used in residential wiring for controlling lights or outlets from a single location.

Question 8

____ are distribution points for electrical circuits.
A)Panelboards
B)Receptacle outlets
C)Surface raceways
D)Lighting outlets

Accepted Answer

Panelboards are distribution points for electrical circuits, serving as a central location where electrical wiring is distributed to various branches within a building or facility.

Question 9

If the raceway is for use of the ____ system, the line will be broken and an uppercase T will be inserted.
A)transportation
B)telephone
C)tunnel
D)timing

Accepted Answer

The correct answer is B) telephone. In diagrams or schematics related to telecommunications, a line representing a raceway (a conduit for enclosing and protecting electrical or communication wires and cables) that is used for the telephone system is often broken and marked with an uppercase "T" to indicate its purpose. This notation helps in identifying the type of system the raceway is intended for, distinguishing it from others like transportation, tunnel, or timing systems.

Question 17

One type of illumination system consists of rows of strip fluorescents and a ceiling that will transmit light. For this system to be efficient, the surfaces above the luminous ceiling must be ____.
A)installed by the electrician
B)metallic
C)black
D)highly reflective (white)

Accepted Answer

For an illumination system with rows of strip fluorescents and a light-transmitting ceiling to be efficient, the surfaces above the luminous ceiling must be highly reflective (white). This maximizes the amount of light reflected back into the room, enhancing the efficiency of the lighting system.
