UT Electrician study guide
UT Electrician · Work through your exam, one topic at a time.
The Utah electrician licensing examination is the assessment that the state uses to determine whether an applicant is qualified to hold a journeyman or master electrician license and to perform electrical work for the public under that license. Candidates typically reach it after completing the required hours of supervised field experience and any required classroom instruction, then applying through the state licensing authority. The UT Electrician study guide has 9 sections and about 3,110 words.
01General Electrical Knowledge and NEC Structure
NFPA 70 (the NEC) is republished every three years. Article 90 gives scope and enforcement authority.
324 words, about 2 min02Electrical Calculations and Theory
Nearly every calculation question reduces to Ohm's law (E = I × R) and the power equation (P = E × I). For single-phase loads, I = VA ÷ E; for balanced three-phase loads, I = VA ÷ (1.732 × E LL).
360 words, about 2 min03Wiring Methods and Materials
Minimum sizes are 14 AWG copper and 12 AWG aluminum (310.106). Ampacities come from Table 310.16 based on insulation rating and terminal temperature; the 60 °C column applies unless terminals are rated higher.
331 words, about 2 min04Wiring and Protection
Article 210 sets branch-circuit ratings, conductor minimums, receptacle spacing, and GFCI/AFCI requirements. In dwelling units, 210.8 requires GFCI protection for bathroom, kitchen, laundry, garage, outdoor, basement, and unfinished-area receptacles, and 210.12 requires AFCI protection for essentially all 120 V, 15 A and 20 A branch circuits.
312 words, about 2 min05Grounding and Bonding
Article 250 separates two ideas: grounding connects the electrical system to earth, and bonding connects metal parts together to create a low-impedance fault path. The service neutral is the grounded conductor; at the service, it is bonded to the enclosure with the main bonding jumper (250.28) and connected to the grounding electrode conductor.
305 words, about 2 min06Equipment for General Use
This chapter governs the equipment you install every day. Flexible cords and cables (400) may not be used as permanent wiring or as a substitute for fixed wiring.
263 words, about 1 min07Motors, HVAC, and Motor Controls
Motor branch-circuit conductors are sized at 125% of the full-load current from Tables 430.248 (single-phase) or 430.250 (three-phase) - not the nameplate amperes, which is the most common exam trap. Overload protection (430.32) protects the motor from sustained overload and is sized from nameplate current at 115%–125%.
278 words, about 1 min08Special Occupancies, Special Equipment, and Special Conditions
Articles 500–506 classify locations where fire or explosion hazards exist. Class I is flammable gas or vapor; Class II is combustible dust; Class III is ignitable fibers.
601 words, about 3 min09Utah Electrical Statutes, Administrative Rules, and Licensing
Electricians in Utah are licensed under the Construction Trades Licensing Act, Utah Code Title 58, Chapter 55, and administered by the Division of Occupational and Professional Licensing (DOPL) with an Electricians Licensing Board advising on standards, exams, and discipline. The administrative rules implementing the Act appear in the Utah Administrative Code under R156-55b, the Electricians Licensing Rule.
