◉ Per NEC Section 200.6, what are the three general ways to identify
a grounded conductor?
Answer: * By the color of its insulation, markings at the terminals, or
other suitable means. * - NEC Section 200.6 - A grounded conductor,
such as a neutral, or a grounding conductor must be identified either
by the color of its insulation, markings at the terminals, or other
suitable means (per NEC Section 200.6).
◉ In general, a grounded conductor must have a ____ or ____ finish.
Answer: * white; gray * - 1.1.0 - In general, a grounded conductor
must have a white or gray finish.
◉ For grounded conductors larger than what size is it acceptable to
mark the terminations white instead of having continuous white
insulation?
Answer: * No. 6 AWG * - 1.1.0 - When this is not practical for
conductors larger than No. 6 AWG, marking the terminations white
is an acceptable method of identifying a grounded conductor.
,◉ In addition to re-identifying the insulation with white markings,
what other method is an acceptable way to identify a grounded
conductor larger than No. 6 AWG?
Answer: * Tagging * - 1.1.0 - Tagging is also acceptable.
◉ In a residential rough-in, what is the purpose of the bare
grounding conductor?
Answer: * To connect the grounding electrode to the inside panel
grounding bus. * - Roughed-In Residential Feeders - The small wire
is a bare grounding conductor that will connect the grounding
electrode to the inside panel grounding bus.
◉ In general, the ampacity of a conductor must not be less than the
maximum load served, with a notable exception for circuits
supplying what type of equipment?
Answer: * A motor. * - 1.1.1 - ...there are exceptions to this rule,
namely, a branch circuit supplying a motor. Motors and motor
circuits are covered in NEC Article 430.
◉ What is the smallest size copper conductor permitted by NEC
Section 310.3(A) for branch circuits in most locations?
Answer: * No. 14 copper. * - NEC Section 310.3(A) - The smallest size
conductor permitted by NEC Section 310.3(A) for branch circuits in
residential, commercial, and industrial locations is No. 14 copper.
,◉ According to NEC Section 210.18, what determines the rating of a
branch circuit?
Answer: * The rating of the branch circuit overcurrent device. * -
NEC Section 210.18 - The rating of the branch circuit overcurrent
device determines the rating of the branch circuit, per NEC Section
210.18.
◉ If a No. 10 AWG conductor is protected by a 20A circuit breaker,
what is the rating of the branch circuit?
Answer: * A 20A branch circuit. * - 1.1.1 - For example, if a No. 10
AWG 30A conductor is protected by a 20A circuit breaker, then the
circuit is considered a 20A branch circuit, despite the ampacity of
the conductor.
◉ True or False: For a branch circuit supplying receptacles, the
conductor's ampacity must not be less than the rating of the branch
circuit overcurrent protective device.
Answer: * TRUE * - 1.1.1 - Where the branch circuit supplies
receptacles for use with cord-and-plug-connected appliances and
other utilization equipment, the conductor's ampacity must not be
less than the rating of the branch circuit overcurrent protective
device.
◉ Is it permissible to use the 'next higher standard overcurrent
device' on a branch circuit that supplies receptacles for cord-and-
plug appliances?
, Answer: * No, this is not permitted. * - NEC Section 240.4(B) - This is
not permitted, however, when the branch circuit supplies
receptacles where cord-and-plug-connected appliances and similar
electrical equipment could be used...
◉ The 'next higher standard overcurrent device' rule may only be
used when the circuit supplies what type of load?
Answer: * A fixed load. * - 1.1.1 - The next standard fuse or circuit
breaker rating may be used only when the circuit supplies a fixed
load.
◉ The permissible ampacity of conductors used on most electrical
systems is found in which NEC Table?
Answer: * NEC Table 310.16. * - 1.1.1 - The permissible ampacity of
conductors used on most electrical systems is found in NEC Table
310.16.
◉ Conductor ampacities are subject to correction factors when the
ambient temperature around the conductor exceeds ____.
Answer: * 86°F (30°C) * - 1.1.1 - However, the ampacities are subject
to correction factors that must be applied where the ambient
temperature around the conductor exceeds 86°F (30°C).
