Question 4

If a device box has been installed too far back behind a wall, a __________ can be used to bring the edge of the box flush with the wall surface.
A) new box
B) wall shrinker
C) box extender
D) different kind of device

Accepted Answer

A box extender is the best choice to bring the edge of the box flush with the wall surface when it has been installed too far back. This allows for proper installation of devices and cover plates. Installing a new box would be unnecessary and time-consuming, a wall shrinker does not exist and using a different kind of device box may not be compatible with the current wiring setup.

Question 7

The preferred method for connecting a circuit conductor to a device is to form a __________ in the wire, put it under a terminal screw, and tighten the screw properly.
A) terminal loop
B) curve
C) circle
D) jug handle

Accepted Answer

The preferred method for connecting a circuit conductor to a device is to form a terminal loop in the wire, put it under a terminal screw, and tighten the screw properly. This ensures a secure and reliable connection. The other options, such as curve or circle, are not specific enough or may not provide enough contact area for a secure connection. Jug handle is not a commonly used term in electrical wiring terminology.

Question 8

Question 11

Electricians create a split-wired receptacle by removing the __________ between the brass terminal screws on the "hot" side of a duplex receptacle.
A) screw
B) connecting tab
C) strap
D) wire

Accepted Answer

The connecting tab is removed between the brass terminal screws on the "hot" side of a duplex receptacle to create a split-wired receptacle. This tab connects the two screws together, so removing it allows for separate circuits to be connected to each screw.

Question 12

A device intended to provide protection from the effects of arc faults by recognizing characteristics unique to arcing and by functioning to de-energize the circuit when an arc is detected is called a(n) ________________________________________.

Accepted Answer

The answer of A device intended to provide protection from...

Question 13

The proper NEMA designation for a 30-ampere, 125/250-volt grounding-type receptacle installed for an electric clothes dryer is __________.
A) 5-15R
B) 6-30R
C) 14-30R
D) 10-30R

Accepted Answer

The NEMA designation for a 30-ampere, 125/250-volt grounding-type receptacle installed for an electric clothes dryer is 14-30R. The 14 indicates the amperage rating, and the 30 indicates the voltage rating. The R indicates that it is a receptacle, and the grounding feature is also included. Choice A (5-15R) is a 15-ampere, 125-volt grounding-type receptacle commonly used for residential outlets. Choice B (6-30R) is a 30-ampere, 250-volt grounding-type receptacle typically used for large appliances like air compressors. Choice D (10-30R) is a 30-ampere, 125-volt grounding-type receptacle typically used for RVs or boats.

Question 14

The proper NEMA designation for a 15-ampere, 125-volt grounding-type receptacle is __________.
A) 5-15R
B) 5-15P
C) 5-20R
D) 6-15R

Accepted Answer

The NEMA designation for a 15-ampere, 125-volt grounding-type receptacle is 5-15R. The "5" indicates the configuration of the blades and contacts, and the "15" indicates the maximum amperage rating. The "R" indicates that it is a receptacle (as opposed to a plug, which would be designated with a "P"). The other options are not correct for this specific receptacle.

Question 15

On a receptacle, the ____________________ conductor is connected to the silver terminal screw.

Accepted Answer

The answer of On a receptacle, the ____________________ conductor is...

Question 16

__________ connections on devices are a reliable way to terminate circuit conductors to a switch or receptacle device and can save time during installation because a terminal loop is not required to be made.
A) New
B) Push-in
C) Back-wired
D) Straight through

Accepted Answer

Back-wired connections allow for a more straightforward and reliable termination of circuit conductors without the need for creating a terminal loop, thus saving time during installation.

Question 17

If the two conductors to be connected to a single-pole switch are black and a reidentified white, the connection you are using is called a traditional _________________________.

Accepted Answer

The answer of If the two conductors to be connected...

Question 18

When more than one grounded conductor enters a device box, a wiring practice to use so that only one conductor gets connected to the silver terminal screw is to use a(n) ____________________.

Accepted Answer

The answer of When more than one grounded conductor enters...

Question 19

A __________ receptacle is one that has internal shutters that are closed behind the receptacle slots when there is no attachment plug inserted.The shutters open when a plug is inserted allowing the plug (and cord) to become energized.
A) duplex
B) single
C) tamper-resistant
D) GFCI

Accepted Answer

A tamper-resistant receptacle has internal shutters that remain closed unless a plug is inserted into both slots simultaneously, preventing children from inserting objects into the slots and risking electrocution.

Question 20

Section 406.5 specifies that screws used for attaching a receptacle to an electrical box must be machine screws with 32 threads per inch or be the type supplied by a __________ receptacle.

Accepted Answer
