1. What is the primary purpose of the National Electrical Code
(NEC)?
A. To reduce labor costs
B. To provide practical safeguarding of persons and property from
electrical hazards
C. To establish union wage requirements
D. To regulate utility companies
Rationale: The NEC is designed to provide practical safeguards for
people and property from hazards arising from the use of electricity. It
establishes minimum safety standards for electrical installations but is
not intended as a design specification or instruction manual.
, 2. Before beginning work on an energized electrical panel, the first
priority should be to:
A. Gather tools
B. Remove the panel cover
C. De-energize the equipment whenever possible and verify absence
of voltage
D. Notify the building owner
Rationale: Electrical safety begins by eliminating hazards whenever
feasible. Equipment should be de-energized, locked out, tagged out,
and tested to confirm the absence of voltage before work begins.
3. Which conductor is normally connected to earth at the service
equipment?
A. Equipment grounding conductor
B. Ungrounded conductor
C. Grounded (neutral) conductor
D. Traveler conductor
Rationale: The grounded conductor, commonly called the neutral, is
bonded to ground at the service disconnecting means. This establishes
a reference to earth and facilitates fault clearing.
, 4. What color insulation is typically used to identify an equipment
grounding conductor?
A. White
B. Gray
C. Black
D. Green or bare
Rationale: The NEC requires equipment grounding conductors to be
identified by green insulation, green with yellow stripes, or to be bare.
This provides consistent identification throughout installations.
5. A branch circuit supplies:
A. Utility transformers
B. Service conductors
C. Feeders only
D. The final overcurrent device and the outlets connected to it
Rationale: A branch circuit extends from the final overcurrent
protective device to outlets and equipment served by that circuit.
, 6. Which instrument is best for verifying voltage?
A. Clamp ammeter
B. Megohmmeter
C. Multimeter
D. Phase rotation meter
Rationale: A properly rated multimeter is designed to measure voltage
accurately and safely. Electricians should always verify the meter on a
known live source before and after testing.
7. Conductors are primarily sized based upon:
A. Paint color
B. Manufacturer preference
C. Ampacity
D. Raceway length alone
Rationale: Conductors must be selected based on ampacity while
considering factors such as insulation type, ambient temperature, and
conductor bundling.
8. Copper conductors generally have:
