What's on the West Virginia Single Family Dwelling Electrician Exam? A 2023 NEC Study Blueprint
What the West Virginia State Fire Marshal's Single Family Dwelling (SP-SFD) electrician exam covers: 50 multiple-choice questions on the 2023 NEC with calculations built in. West Virginia publishes no outline, so here is a residential study blueprint.
What's on the West Virginia Single Family Dwelling Electrician Exam?
Since January 1, 2026, the State Fire Marshal's Single Family Dwelling exam has the same format as the journeyman and master exams: 50 multiple-choice questions, each worth 2 points, open book on the 2023 NEC. You have 4 hours and need 70% (35 questions). Calculations are built into the multiple choice.
There is no official outline
West Virginia's rule says only that every exam is "derived from the National Electrical Code" and appropriate to the license applied for. The State Fire Marshal does not publish how many questions come from each topic. So the blueprint below is ours, not the state's. We started from our journeyman blueprint and narrowed it to the NEC articles a single family dwelling electrician works under, giving more weight to dwelling branch circuits, services and load calculations.
| Area (our blueprint) | NEC | Questions |
|---|---|---|
| Branch Circuits, Feeders, Services and Overcurrent Protection | Articles 200-240 | 10 |
| Wiring Methods and Materials | Chapter 3 (NM, UF, SE, AC, MC, raceways, burial depths) | 10 |
| Dwelling Calculations | Article 220, Chapter 9, box fill | 9 |
| Grounding and Bonding | Article 250 | 6 |
| Equipment for General Use | Chapter 4 (switches, receptacles, luminaires, appliances, heating, A/C) | 6 |
| General Requirements and Definitions | Articles 90, 100, 110 | 4 |
| Special Occupancies and Equipment | Manufactured homes (550), EV charging (625), pools and spas (680), solar PV (690) | 3 |
| Special Conditions and Communications Systems | Standby power, energy storage, Chapter 8 | 2 |
| Total | 50 |
What to know cold
- Dwelling receptacle rules (210.52): countertop spacing, small-appliance circuits, bathroom, laundry, garage, outdoor and hallway outlets.
- GFCI and AFCI (210.8, 210.12): which dwelling locations and appliances need protection.
- Services (Article 230): the minimum 100-ampere disconnect for a one-family dwelling and the emergency disconnect required for one- and two-family dwellings (230.85).
- Service and feeder conductor sizing (310.12): the 83% rule for single-phase dwelling services.
- Load calculations (Article 220, Parts III and IV): the standard method (general lighting, small-appliance and laundry loads, Table 220.55 ranges, dryers) and the optional method (220.82, 220.83).
- NM cable (Article 334) and box fill (314.16).
What changed with the 2023 NEC
Before 2026 the exam was on the 2020 NEC. If your study material is older, watch for:
- Electric vehicle charging loads now count at 7,200 VA or the nameplate, whichever is larger (220.57).
- GFCI protection for specific appliances (210.8(D)) now lists electric ranges, wall-mounted ovens, counter-mounted cooking units, clothes dryers and microwave ovens, alongside dishwashers and sump pumps.
- Class 1 remote-control and signaling circuits moved from Article 725 to Article 724.
How to study
- Learn the book's layout. With 50 questions in 4 hours, you have almost 5 minutes a question, so finding a section quickly matters more than memorizing it.
- Tab Articles 210, 220, 250, 310 and 334, and the Chapter 9 tables. Those answer a large share of residential questions.
- Practice the calculations. Expect a dwelling service calculation, ampacity with correction factors and box fill inside the multiple choice.
Our West Virginia Single Family Dwelling Electrician practice test draws from these areas in the same proportions, and every question cites its 2023 NEC section. For eligibility and fees, see the requirements.
