Question 5

A light dimmer ____ be used as a speed control for a ceiling fan or other motor.

Accepted Answer

A light dimmer should not be used as a speed control for a ceiling fan or other motor. Light dimmers are designed to regulate the intensity of incandescent bulbs by reducing the amount of power flowing through them. However, this method of control is not suitable for motors or induction-based devices like ceiling fans, as it can cause damage to the motor and reduce its lifespan. Additionally, it can create a fire hazard and is a safety risk. Therefore, it is recommended to use a speed control specifically designed for motor-based devices.

Question 6

Sliding glass panels ____ considered to be wall space, the same as any other interior or exterior door.

Accepted Answer

Since sliding glass panels are not fixed and are movable, they cannot be considered as wall space, but instead as part of the opening they cover. Therefore, they are not the same as any other interior or exterior door.

Question 7

Some types of panels and similar building elements are considered wall space when figuring receptacle spacing, and others are not. Match the following.
-Sliding glass panel

Accepted Answer

Sliding glass panels are not considered wall space for determining receptacle spacing according to the National Electrical Code. Therefore, receptacles are not required to be installed within 6 feet of the panel.

Question 8

Question 10

During the winter, it is suggested that a paddle fan should ____.

Accepted Answer

During the winter, it is suggested that a paddle fan should draw air up. This helps to redistribute warm air that rises to the ceiling throughout the room, improving energy efficiency and comfort.

Question 11

A raised plaster cover (often called a plaster ring or mud ring) is permitted to increase the maximum number of conductors permitted in an outlet box when it is ____.

Accepted Answer

Plaster rings or mud rings can increase the maximum number of conductors permitted in an outlet box if they are marked with their cubic-inch volume. This marking allows for the calculation of the total volume available for conductors and devices, ensuring compliance with the National Electrical Code (NEC) requirements for box fill.

Question 12

The selection of outlet boxes and switch boxes is made by the electrician. These decisions are based on Code requirements, space allowances, good wiring practices, and ____.

Accepted Answer

Good wiring practices include considerations such as ease of access for future maintenance and ensuring adequate support for the boxes. While homeowner preferences and cost may be factors, they should not be the primary considerations when selecting boxes for electrical installations. Code requirements and city building codes will dictate minimum standards, but good wiring practices should always be followed in addition to those standards.

Question 13

How can you tell whether a metallic or nonmetallic outlet box is suitable for safely supporting a ceiling fan?

Accepted Answer

The answer of How can you tell whether a metallic...

Question 14

Ceiling fan speed can be controlled by ____.

Accepted Answer

All of the choices listed (pull chain, wall control, and remote control) are viable options for controlling the speed of a ceiling fan. The best choice would depend on personal preference and convenience. Some people may prefer the simplicity of a pull chain, while others may prefer the convenience of a remote control. A wall control may be the best choice for those who want a more permanent and streamlined option. Ultimately, any of these options would effectively control the speed of the ceiling fan.

Question 15

Some types of panels and similar building elements are considered wall space when figuring receptacle spacing, and others are not. Match the following.
-Fixed room divider

Accepted Answer

Fixed room dividers are considered wall space, and therefore, receptacles are required according to the National Electrical Code (NEC) guidelines for receptacle spacing.

Question 16

Some ceiling fan/light units have one lamp socket, whereas others have ____ lamp sockets.

Accepted Answer

Most ceiling fan/light units have only one lamp socket, but some larger ones may have four or five sockets. It is rare to find a ceiling fan with more than five sockets. Therefore, the best choice is A.

Question 17

Some types of panels and similar building elements are considered wall space when figuring receptacle spacing, and others are not. Match the following.
-Fixed glass panel

Accepted Answer

The answer of Some types of panels and similar building...

Question 18

Receptacle outlets must be installed in any wall space ____ or more in width.

Accepted Answer

Receptacle outlets must be installed in any wall space 24 in. (600 mm) or more in width, according to the National Electrical Code (NEC) requirements, to ensure accessibility and convenience in using electrical appliances.

Question 19

Which of the following is NOT a reason that ceiling fans must be specially supported?

Accepted Answer

Safe grounding is important for electrical safety, but it is not a reason why ceiling fans must be specially supported. The weight, torque, and vibration of the fan can put stress on the electrical box it is mounted to, which is why it is important to use a box rated for ceiling fan installation and to ensure proper installation and support of the fan itself.

Question 20

Fan speed controllers have internal circuitry that is engineered specifically for use on inductive circuits. Do not use a standard ____________________ to control fan motors.

Accepted Answer

The answer of Fan speed controllers have internal circuitry that...
