Advanced Supervisory Practice
Examination 2026 | 100 Questions &
Answers with Detailed Rationales |
Complete Exam Prep & Study Guide
1. Which Hawaii license category specifically covers a person licensed to
maintain electrical work?
A. Journey Worker Electrician
B. Supervising Electrician
C. Maintenance Electrician
D. Supervising Specialty Electrician
Answer: Maintenance Electrician
Rationale: Hawaii law defines a maintenance electrician as a person licensed by
the Board to maintain electrical work.
2. A maintenance electrician is assigned to supervise another maintenance
electrician performing work within the maintenance scope. Which
statement best reflects Hawaii Board guidance?
A. Only an ES may supervise an EM
B. An EM may supervise another EM
C. Only an ESI may supervise an EM
D. An ESS must supervise all EM work
,Answer: An EM may supervise another EM
Rationale: Hawaii Board guidance specifically indicates that a maintenance
electrician may supervise another maintenance electrician.
3. Which license is specifically intended for directing and supervising electrical
work generally?
A. EM
B. EJS
C. ES
D. ESS
Answer: Supervising Electrician
Rationale: Hawaii defines the supervising electrician as a licensee authorized to
direct and supervise electrical work and perform electrical work.
4. A maintenance supervisor is reviewing a proposed job that involves
installing new electrical wiring as part of a major construction project. What
should be determined first?
A. Whether the work falls within the EM maintenance scope
B. Whether the equipment is painted
C. Whether the workers have tools
D. Whether the existing breaker is large enough
Answer: Whether the work falls within the EM maintenance scope
Rationale: A maintenance electrician should not assume that all electrical work
at an existing facility qualifies as maintenance. The scope and licensing
requirements must be evaluated before work begins.
5. Which document is most useful for determining the actual configuration of
a facility's electrical distribution system?
A. Equipment warranty
B. One-line diagram
,C. Purchase receipt
D. Safety poster
Answer: One-line diagram
Rationale: A one-line diagram provides a simplified representation of major
electrical sources, feeders, transformers, switchgear, and distribution
equipment.
6. A maintenance supervisor discovers that the facility one-line diagram does
not match the actual installation. What should be done?
A. Ignore the discrepancy
B. Update the documentation after verifying the actual installation
C. Remove the one-line diagram
D. Replace the main breaker
Answer: Update the documentation after verifying the actual installation
Rationale: Accurate electrical documentation is essential for troubleshooting,
lockout/tagout, system planning, and emergency response.
7. A 20-ampere branch circuit supplies general-purpose receptacles. Which
copper conductor is normally appropriate under standard conditions?
A. 18 AWG
B. 16 AWG
C. 12 AWG
D. 8 AWG
Answer: 12 AWG
Rationale: A typical 20-ampere branch circuit requires 12 AWG copper
conductors unless a specific code provision permits another arrangement.
8. A conductor is installed in an environment with elevated ambient
temperature. What should the supervisor evaluate?
, A. Temperature correction requirements
B. Panel color
C. Receptacle shape
D. Ground rod appearance
Answer: Temperature correction requirements
Rationale: Elevated ambient temperature can reduce conductor ampacity and
may require correction according to applicable electrical code requirements.
9. Several current-carrying conductors are installed together in a raceway.
What issue must be evaluated?
A. Conductor ampacity adjustment
B. Transformer oil level
C. Panelboard paint
D. Lighting color
Answer: Conductor ampacity adjustment
Rationale: Multiple current-carrying conductors can increase heat accumulation
and may require ampacity adjustment.
10.What is the primary purpose of an overcurrent protective device?
A. Increase voltage
B. Protect conductors and equipment from excessive current
C. Eliminate grounding
D. Increase motor horsepower
Answer: Protect conductors and equipment from excessive current
Rationale: Fuses and circuit breakers are designed to interrupt excessive current
before conductors or equipment are damaged.
11.A breaker repeatedly trips immediately after being reset. What should the
supervisor do?
