Rationale: The City of Evanston identifies NFPA 70/2020, with local
amendments, as its adopted National Electrical Code. Exam
preparation should therefore emphasize the 2020 NEC unless a
particular project is governed by another specifically applicable
requirement.
,2. Before permit issuance when electrical work is proposed at an
Evanston job site, which document is specifically required?
A. Plumbing worksheet
B. Mechanical worksheet
C. Electrical worksheet
D. Zoning variance
Rationale: Evanston requires an Electrical Worksheet to be submitted

and property.
4. What is the primary purpose of overcurrent protection?
,A. Increase conductor voltage
B. Improve power factor
C. Protect conductors and equipment from excessive current
D. Increase motor speed
Rationale: Circuit breakers and fuses are primarily intended to protect
conductors and equipment against excessive current caused by
overloads, short circuits, and related fault conditions.
5. What is the general maximum rating of a standard single-pole
branch-circuit breaker supplying general-purpose receptacles with 12
AWG copper conductors, assuming no special limitation applies?
A. 15 amperes
B. 20 amperes
C. 25 amperes

governing conductor ampacity and permitted overcurrent protection.
6. Which NEC article primarily covers branch-circuit requirements?
, A. Article 90
B. Article 100
C. Article 210
D. Article 430
Rationale: Article 210 addresses branch circuits, including branch-
