Grounded and Ungrounded Conductors

Question 1

Defined as a system or circuit conductor that is intentionally grounded.

Answer 1

Grounded Conductor

Question 2

serves
as the grounded leg of the circuit. It completes the circuit by
connecting the ungrounded (hot) conductor to ground.

Answer 2

grounded conductor in single branch circuits

Question 3

in circuit design, the _______ is considered to be
a current carrying conductor because it serves as a return
path back to the circuit’s power source.

Answer 3

grounded conductor

Question 4

performs the function of a
grounded conductor for at least two ungrounded
(hot) conductors that have sources from different
voltage phases, such as on a multiwire branch circuit,
multiwire feeder, and the electrical service.

Answer 4

neutral conductor

Question 5

It is a
grounded conductor that is shared between two or
more ungrounded conductors.

Answer 5

neutral conductor

Question 6

frequently called a shared neutral or
common neutral.

Answer 6

neutral
conductor

Question 7

Also called the hot wires

Answer 7

Ungrounded conductors

Question 8

is the practice of dividing loads as
evenly as possible between the ungrounded
conductors on a multiwire circuit, feeder, or service.

Answer 8

Load Balancing

Question 9

offers excess
electricity the most
effective and safest route
from an appliance back to
the ground by way of
an electrical panel.

Answer 9

Grounding

Question 10

is a
backup pathway that is
generally only used if a
fault in the wiring system

Answer 10

Electrical grounding

Question 11

It is a continuous
conductor that connects
the ground to the neutral
bus bar and the grounding
conducting bus bar in the
service equipment/main
panelboard.

Answer 11

Grounding Conductor

Question 12

It safely carry current to
ground in the event of a
lightning strike or in cases
of damage or defect in the
circuiting, appliances,
devices, or equipment, It
also provide safety feature to the wiring system

Answer 12

Grounding Conductor uses

(connecting) all building electrical
system components at the service
entrance equipment at the
______ of the ___________ or __________.

Answer 14

neutral bus, main
panelboard, switchboard

Question 15

Refers to a grounding conductor or grounding path that connects the non-current carrying metal components of equipment

Answer 15

Equipment Grounding

Question 16

It is accomplished by installing an additional grounding conductor or by permanently joining metal components in a circuit.

Answer 16

Bonding

Question 17

a bare conductor or a green-
colored, insulated conductor that connects (bonds) the outlet boxes,
metallic raceways, other enclosures and frames on motors,
appliances, and other electrical equipment.

Answer 17

EQUIPMENT-GROUNDING CONDUCTOR

Question 18

protects the user from
electric shock by creating a
nonconducting barrier between the
user and the electric components inside
the appliance or tool.
