Question 1

Paint used on electrical enclosures functions as a conductor.

Accepted Answer

Paint used on electrical enclosures should function as an insulator to prevent electrical conductance and potential hazards.

Question 2

In its simplest form, ____ completes a path through which fault current can flow.
A) bonding
B) grounding
C) bending
D) shunting

Accepted Answer

A

Question 3

Electrical systems that are ____ must be connected to the earth in a way that will (1) limit the voltage imposed by lightning, line surges, or unintentional contact with higher-voltage lines and (2) stabilize the voltage of the system to the earth during normal operations.
A) cycled
B) shunted
C) grounded
D) bonded

Accepted Answer

Electrical systems that are grounded must be connected to the earth in a way that limits voltage and stabilizes the voltage of the system during normal operations. Bonding refers to connecting two conductive objects together to ensure electrical continuity, while cycling and shunting do not relate to the grounding of electrical systems.

Question 4

The purpose of connecting non-current-carrying conductive materials to earth is to limit the ____ on these materials.
A) interference
B) maximum amperage
C) resistivity
D) voltage to ground

Accepted Answer

Connecting non-current-carrying conductive materials to earth is known as grounding or earthing. The purpose of this is to limit the voltage on these materials, which can occur from static electricity, electrical faults, or lightning strikes. Grounding provides a path for the current to flow to earth, rather than through equipment or people, which can be dangerous. This helps to protect both people and equipment from electric shock and damage.

Question 5

The NEC is generally written in "____________________ style," stating how an installation must be made, rather than "performance style," stating general goals to be achieved.

Accepted Answer

The answer of The NEC is generally written in "____________________...

Question 6

Bonding must be accomplished around conduit connections whenever the fault-current return path is suspect, as well as when specifically required by NEC .

Accepted Answer

Bonding is necessary around conduit connections to ensure the path for fault currents is low impedance and reliable, and the NEC also requires bonding in certain situations.

Question 7

The ____ of an article tells us what is contained in an article.
A) definitions
B) scope
C) requirements
D) discussion

Accepted Answer

The scope of an article outlines the specific topic or subject matter that will be discussed within the piece. It provides a clear indication of what readers can expect to learn or gain insight into by reading the article. Definitions, requirements, and discussion may all be included within the scope, but they are not the primary focus - instead, they serve to support or expand upon the main topic.

Question 8

Some manufacturers of data processing equipment refer to a conduit or branch-circuit as a(n) "____________________," because of the electrical interference or noise that travels on this path.

Accepted Answer

The answer of Some manufacturers of data processing equipment refer...

Question 9

The electrical system is generally considered to be the source of electrical energy.

Accepted Answer

The electrical system is designed to generate, distribute, and regulate the flow of electrical energy, making it the source of electrical energy in various applications.

Question 10

____ current occurs when the system neutral is grounded improperly downstream from the service equipment.
A) Positive
B) Negative
C) Phased
D) Objectionable

Accepted Answer

Objectionable current occurs when the system neutral is grounded improperly downstream from the service equipment. This can result in stray currents flowing through metal objects, such as water pipes, and can cause corrosion or even electric shock.
