Question 1

What type of branch circuit has two or more ungrounded conductors that have a voltage between them, and a grounded conductor that is connected to the neutral or grounded conductor of the system, with equal voltage between it and each ungrounded conductor of the circuit?

Accepted Answer

The correct term is "multiwire" (though misspelled as "multiware" in the options), which describes a branch circuit that has two or more ungrounded conductors with a voltage between them and a grounded conductor that has equal voltage between it and each ungrounded conductor, sharing a common neutral.

Question 2

A(n)____ can be used to control lighting loads so they operate only when a room is occupied.

Accepted Answer

Occupancy sensors detect the presence of people in a room and can control lighting (among other systems) to ensure lights are on only when the room is occupied, saving energy by turning lights off when the room is empty.

Question 3

What type of branch circuit is meant by a shared-neutral branch circuit?

Accepted Answer

A shared-neutral branch circuit, often referred to as a multiwire branch circuit, involves two or more circuits that share a common neutral wire. This configuration can reduce the amount of wiring needed and can be more efficient in certain installations.

Question 5

The purpose of a(n)____ device is to protect the circuit wiring and devices and to some extent the equipment served by the circuit.

Accepted Answer

Overcurrent protection devices, such as fuses and circuit breakers, are designed to protect electrical circuits and devices from excessive current, which can cause overheating and potentially start fires. They do this by interrupting the flow of electricity when the current exceeds a safe level.

Question 6

A continuous load is one that is expected to operate for a period of ____ hours or more.

Accepted Answer

A continuous load is defined as a load expected to operate for three hours or more.

Question 7

If the load is a water heater with capacity of 120 gallons (450 L)or less, the branch circuit is required to be included as a(n)____ load.

Accepted Answer

A water heater with a capacity of 120 gallons or less is considered a continuous load because it can operate for three hours or more continuously.

Question 8

What type of load is considered a type M load?

Accepted Answer

Type M load refers to motor loads, which include devices and appliances that operate using motors.

Question 11

For conductors larger than 1 AWG or for overcurrent devices rated greater than 100 amperes, the default rating of terminals is ____ degrees C.

Accepted Answer

The default rating of terminals for conductors larger than 1 AWG or for overcurrent devices rated greater than 100 amperes is 75 degrees C, according to the National Electrical Code (NEC).

Question 12

When sizing conductors and overcurrent protection, you must take 100 percent of the noncontinuous loads plus ____ percent of the continuous loads.

Accepted Answer

The National Electrical Code (NEC) requires that conductors and overcurrent protection be sized to handle 100% of noncontinuous loads plus 125% of continuous loads to ensure safety and reliability.

Question 13

When a branch circuit supplies an air conditioning system that consists of a hermetic motor-compressor and other loads, the circuit rating must not exceed ____ percent of the hermetic motor load plus the sum of the additional loads.

Question 16

For motors, the OCPDs are ____.

Accepted Answer

Inverse-time circuit breakers are used as OCPDs for motors because they provide a time delay before tripping, which allows the motor to start and reach its operating speed before the circuit breaker trips.

Question 18

What type of branch circuit supplies two or more receptacles or outlets for lighting and appliances?

Accepted Answer

General-purpose branch circuits are designed to supply two or more receptacles or outlets for lighting and appliances, providing a versatile power solution for various needs within a building.

Question 19

The branch circuit begins at the final ____ and ends at the device or equipment being supplied.

Accepted Answer

The branch circuit begins at the final overcurrent device protecting the circuit and ends at the device or equipment being supplied. This overcurrent device could be a circuit breaker or fuse in a panelboard that provides protection against excessive currents which could damage the wiring or devices.

Question 20

Multioutlet branch-circuit ratings are limited to 15-, 20-, 30-, 40-, and 50-ampere except on ____ premises, where they may have a higher rating.

Accepted Answer

Industrial premises may have multioutlet branch-circuit ratings with a higher rating than the standard 15-, 20-, 30-, 40-, and 50-ampere due to the higher power demands typically found in industrial settings.
