(Questions 1–15)
QUESTION 1.
A residential contractor is installing a new 200-ampere single-phase dwelling service.
Before selecting conductors, the contractor must determine the calculated load in
accordance with the National Electrical Code. What is the primary purpose of
performing a dwelling load calculation?
A. To maximize conductor size regardless of demand
B. To determine the minimum ampacity required based on calculated demand
C. To reduce grounding conductor size
D. To eliminate the need for overcurrent protection
Correct Answer: B. To determine the minimum ampacity required based on
calculated demand
,Explanation: NEC load calculations are used to establish the expected electrical
demand so that service conductors, feeders, and overcurrent devices are appropriately
sized. Oversizing conductors without calculation is unnecessary and costly, while
undersized conductors create overheating hazards. Grounding conductor sizing and
overcurrent protection remain separate code requirements.
QUESTION 2.
A contractor installs NM cable through multiple bored holes in wood framing.
Several current-carrying conductors are bundled together for an extended distance.
Which NEC consideration becomes most important?
A. Voltage polarity
B. Conductor ampacity adjustment due to bundling
C. Ground rod spacing
D. Fixture mounting height
Correct Answer: B. Conductor ampacity adjustment due to bundling
Explanation: Bundled current-carrying conductors generate additional heat. The NEC
requires ampacity adjustment factors when more than the permitted number of
conductors are installed together for sufficient distances. Polarity, grounding electrode
spacing, and fixture heights are unrelated to this thermal issue.
QUESTION 3.
During inspection, a contractor observes that the grounded (neutral) conductor and
equipment grounding conductors are connected together inside a downstream
subpanel in a detached garage. What is the inspector most likely to require?
A. Increase breaker size
B. Bond the neutral to the enclosure more securely
, C. Separate the grounded conductor from equipment grounding conductors
D. Replace all branch-circuit wiring
Correct Answer: C. Separate the grounded conductor from equipment grounding
conductors
Explanation: In downstream distribution equipment, neutrals must remain isolated
from equipment grounding conductors. Bonding them together beyond the service
disconnect creates parallel return paths that may energize normally non-current-
carrying metal parts, creating shock hazards. The other options do not correct the code
violation.
QUESTION 4.
A homeowner requests additional receptacles in a kitchen renovation. Which
receptacle location is most likely required to have GFCI protection under the NEC?
A. Bedroom wall receptacle
B. Hallway receptacle
C. Kitchen countertop receptacle
D. Dining room ceiling outlet
Correct Answer: C. Kitchen countertop receptacle
Explanation: Kitchen countertop receptacles are located in areas where moisture and
portable appliances increase shock hazards. GFCI protection significantly reduces the
risk of electrocution. Standard bedroom, hallway, and ceiling lighting outlets generally
are not covered by this specific GFCI requirement.
QUESTION 5.
A contractor measures 122 volts at the service equipment but only 114 volts at a
detached accessory building during heavy loading. Which design consideration
