1. What is the primary purpose of the Michigan Sign Specialist license?
A. Authorize general plumbing installations
B. Authorize unlimited electrical contracting work
C. Recognize qualification to perform regulated work involving electric signs and
related wiring
D. Authorize structural engineering inspections
Correct Answer: C. Recognize qualification to perform regulated work involving
electric signs and related wiring
Rationale: The Michigan Sign Specialist license is specifically associated with the
manufacture, installation, maintenance, connection, and repair of electric signs
and related wiring. It is not a general electrical contractor or plumbing license.
2. What is the minimum age generally required for a Michigan Sign Specialist
license?
A. 16
B. 18
C. 20
D. 22
Correct Answer: B. 18
,Rationale: Michigan's current licensing information identifies 18 as the minimum
age for a Sign Specialist applicant. The age requirement differs from some other
electrical licenses.
3. What experience requirement is specified for a Michigan Sign Specialist
applicant using the standard experience pathway?
A. 1,000 hours over one year
B. 2,000 hours over one year
C. 4,000 hours over at least two years
D. 8,000 hours over four years
Correct Answer: C. 4,000 hours over at least two years
Rationale: Michigan's Sign Specialist licensing requirements call for at least 4,000
hours of qualifying experience obtained over at least two years in work related to
electric signs and associated wiring.
4. Which type of work qualifies within the Sign Specialist experience
description?
A. Residential painting
B. Plumbing fixture installation
C. Installation of electric signs and related wiring
D. Landscape maintenance
Correct Answer: C. Installation of electric signs and related wiring
Rationale: Qualifying experience includes work related to the manufacture,
installation, maintenance, connection, or repair of electric signs and related
wiring.
5. What is the current passing score for the Michigan Sign Specialist
examination?
,A. 60%
B. 65%
C. 70%
D. 75%
Correct Answer: D. 75%
Rationale: The current PSI Candidate Information Bulletin lists 75% as the
minimum passing score for the Sign Specialist examination.
6. What is the current time allowed for the Michigan Sign Specialist
examination?
A. 30 minutes
B. 45 minutes
C. 60 minutes
D. 90 minutes
Correct Answer: C. 60 minutes
Rationale: The current PSI bulletin specifies 60 minutes for the 32-question Sign
Specialist examination.
7. Which NEC article specifically addresses electric signs and outline lighting?
A. Article 250
B. Article 430
C. Article 517
D. Article 600
Correct Answer: D. Article 600
Rationale: Article 600 of the NEC contains requirements specifically addressing

place particular emphasis on this article.
, 8. What is a fundamental purpose of grounding and bonding in a sign
installation?
A. Increase lamp brightness
B. Reduce sign dimensions
C. Provide a safe path for fault current and help establish effective fault-clearing
conditions
D. Increase advertising visibility
Correct Answer: C. Provide a safe path for fault current and help establish
effective fault-clearing conditions
Rationale: Grounding and bonding help establish conductive paths for fault
current and support operation of overcurrent protection during faults. They also
reduce dangerous voltage differences between conductive parts.
9. Which conductor normally provides the intentional connection between
equipment and the grounding system?
A. Ungrounded conductor
B. Neutral conductor only
C. Signal conductor
D. Equipment grounding conductor
Correct Answer: D. Equipment grounding conductor
Rationale: The equipment grounding conductor provides a low-impedance path
for fault current between electrical equipment and the grounding system.
10. What is the primary purpose of bonding metallic sign components that
require bonding?
A. Increase the sign's illuminated area
B. Maintain electrical continuity between conductive parts for fault-current
purposes
C. Reduce the weight of the sign
D. Increase conductor resistance
