Question 4

When a luminaire is connected to the conductors, the outlet is referred to as a ____ outlet.

Accepted Answer

A luminaire outlet is specifically referred to as a lighting outlet when it is connected to conductors for the purpose of providing illumination.

Question 5

The sound level rating used to define fan noise is expressed in ____.

Accepted Answer

The sound level rating used to define fan noise is expressed in sones. Decibels are a measure of sound intensity or pressure, but sones take into account the frequency response of the human ear, making it a more accurate measure for assessing noise perception. Tenor is a type of male singing vocal range, and range is a generic term that could refer to a variety of things, but is not specific enough to be the correct answer.

Question 6

What piece of kitchen equipment is permitted to be connected to the two 20-ampere small-appliance circuits required for the kitchen and dining room area?

Accepted Answer

The clock outlet is the only piece of kitchen equipment from the options given that is permitted to be connected to the two 20-ampere small-appliance circuits required for the kitchen and dining room area. This is in accordance with the National Electrical Code (NEC), which specifies the types of outlets and appliances that can be connected to these dedicated circuits.

Question 7

GFCI protection can be provided for convenience receptacles serving kitchen countertop areas by ____.

Accepted Answer

All of the options - installing GFCI circuit breakers, GFCI-protected receptacles at each location, or a single feed-through type GFCI receptacle to protect downstream receptacles - can provide GFCI protection for convenience receptacles serving kitchen countertop areas. The best choice depends on the specific situation and wiring configuration.

Question 8

NEC 422.16(B)(4) permits a range hood to be cord-and-plug connected. The receptacle would be installed ____ the range.

Accepted Answer

According to NEC 422.16(B)(4), for a range hood to be cord-and-plug connected, the receptacle is typically installed inside the cabinetry above the hood. This allows for a neat installation that keeps the cord and receptacle hidden and out of the way.

Question 9

A popular use of ____________________ is to control one receptacle with a switch and leave one receptacle "hot" at all times.

Accepted Answer

The answer of A popular use of ____________________ is to...

Question 10

Cord-and-plug-connected appliances shall not exceed ____ percent of the branch-circuit rating.

Accepted Answer

According to NEC 210.23(A)(2), cord-and-plug-connected appliances shall not exceed 80 percent of the branch-circuit rating.

Question 11

Most duplex receptacles can be changed into "split-wired" receptacles by ____.

Accepted Answer

Breaking off the small metal tab on the terminals allows each outlet to be wired independently and receive power from separate circuits, creating a split-wired receptacle.

Question 12

The load for each small-appliance, branch circuit load is required to be calculated at ____.

Accepted Answer

The correct calculation for each small-appliance branch circuit load is 1,500 volt-amperes, as per the National Electrical Code (NEC) guidelines.

Question 13

The receptacle for a kitchen refrigerator is permitted to be supplied by a(n) ____________________ branch circuit.

Accepted Answer

The answer of The receptacle for a kitchen refrigerator is...

Question 14

Countertop receptacles must be served by at least ____-ampere small appliance circuits.

Accepted Answer

Countertop receptacles in kitchens require at least two 20-ampere circuits to ensure they can handle the load of small appliances typically used in these areas. This is a safety and capacity consideration to prevent overloading and potential electrical hazards.

Question 15

When installing a multiwire branch circuit, a means must be provided to simultaneously disconnect all of the hot conductors at the panelboard where the circuit originates. This means is normally a(n) ____________________.

Accepted Answer

The answer of When installing a multiwire branch circuit, a...

Question 16

Kitchen lighting ____ permitted to be supplied by the two 20-ampere small-appliance circuits required for the kitchen and dining room area.

Accepted Answer

According to the National Electrical Code, kitchen lighting cannot be supplied by the two 20-ampere small-appliance circuits required for the kitchen and dining room area. These circuits are reserved for the specific use of kitchen appliances and outlets, and cannot be shared with general lighting.

Question 17

Because of the dangers associated with the open neutral (grounded conductor), NEC 300.13(B) does not permit the continuity of the ____ conductor to depend on a receptacle.

Accepted Answer

NEC 300.13(B) prohibits the continuity of the grounded (neutral) conductor to rely on a receptacle because it can lead to dangerous conditions such as overloading and potential shock hazards.

Question 18

The 125-volt, 20-ampere receptacles installed to serve kitchen countertops are required to have GFCI protection ____.

Accepted Answer

According to the National Electrical Code (NEC), all 125-volt, 20-ampere receptacles installed to serve kitchen countertops are required to have Ground Fault Circuit Interrupter (GFCI) protection. There are no exceptions based on the distance from the sink or the presence of assured grounding conductor protection. Therefore, choice B is the correct answer.

Question 19

A 125-volt, 15- and 20-ampere receptacle installed to serve a kitchen countertop is required ____.

Accepted Answer

A 125-volt, 15- and 20-ampere receptacle installed to serve a kitchen countertop is required to be supplied by at least two 20-ampere small appliance circuits as per NEC 210.52(B)(1). It is also required to have GFCI protection for personnel as per NEC 210.8(A)(6). Therefore, option D is the correct answer. Option C is not required by the NEC, but it is a good practice to locate receptacles within 24 inches of the sink to reduce the use of extension cords in wet areas.

Question 20

A(n) ____ receptacle can be hidden behind a painting or photograph that you want to light up.
