NE Journeyman Electrician study guide
NE Journeyman Electrician · Work through your exam, one topic at a time.
The Nebraska Journeyman Electrician credential is a state-issued license that allows you to perform electrical work independently under the scope defined by Nebraska law, typically while working under or alongside a master electrician depending on the arrangement. It is aimed at electricians who have completed the required supervised field experience and are ready to move from apprentice-level work to running installations on their own. The NE Journeyman Electrician study guide has 10 sections and about 2,685 words.
01General Electrical Knowledge and Theory
This domain tests the physics behind the Code: Ohm's law, power, series and parallel circuits, AC values, conductor resistance, and voltage drop. Expect calculation items, not just definitions.
283 words, about 1 min02Wiring Methods and Materials
This domain covers NEC Chapter 3: choosing cables and raceways, support and securing, boxes, wet and damp locations, and permitted uses. Exam items often ask whether a method is allowed in a location.
298 words, about 1 min03Grounding and Bonding
This domain tests Article 250: the grounded conductor, equipment grounding conductor, grounding electrode system, bonding, and the fault-current path. The exam separates grounding (earth connection) from bonding (metal parts joined).
263 words, about 1 min04Overcurrent Protection and Short-Circuit Current Ratings
This domain covers Article 240 and interrupting ratings: selecting OCPDs, continuous-load sizing, standard ratings, tap rules, series ratings, and SCCR for equipment. Continuous loads are calculated at 125% for branch-circuit and feeder OCPD sizing, unless the Code says otherwise.
271 words, about 1 min05Branch Circuits, Feeders, and Service Calculations
This domain tests Article 220 load calculations and Article 210 branch-circuit rules: receptacle spacing, small-appliance and laundry circuits, lighting VA, demand factors, and service sizing. Dwelling general lighting: 3 VA/ft²; small-appliance: two 1,500 VA circuits; laundry: 1,500 VA.
257 words, about 1 min06Motors, HVAC, and Motor Control Circuits
This domain covers Articles 430 and 440: motor FLC tables, conductor sizing, overload protection, branch short-circuit protection, disconnects, and HVAC nameplate values. Use Tables 430.248 and 430.250 for motor full-load current, not the motor nameplate FLA, for branch conductors and overloads.
257 words, about 1 min07Transformers and Special Occupancies
This domain covers Article 450 transformer protection and Articles 500–517, 680, and 690 for hazardous locations, health care, pools, and solar. The exam tests both transformer calculations and location-specific restrictions.
241 words, about 1 min08Boxes, Raceways, Conductors, and Cable Fill
This domain tests Articles 300, 310, 314, and Chapter 9: box fill, conduit fill, conductor ampacity, derating, pull boxes, and support. Box fill is calculated by counting conductors, clamps, devices, and grounds using Table 314.16(B) volumes; grounds count once.
257 words, about 1 min09Nebraska Electrical Statutes, Rules, and Licensing Requirements
This domain tests Nebraska's Electrical Licensing Act, Neb. §§ 81-2101 et seq., and State Electrical Board rules: license types, experience, exams, permits, inspections, and enforcement.
279 words, about 1 min10Nebraska Electrical Statutes, Rules, and Licensing Requirements
This domain tests Nebraska's Electrical Licensing Act, Neb. §§ 81-2101 et seq., and State Electrical Board rules: license types, experience, exams, permits, inspections, and enforcement.
