Single Family Dwelling Mock Exam (2020 NEC)
Score yourself on the Single Family Dwelling exam before the state does: 140+ practice questions with NEC answer references.
Includes a printed mock exam booklet with 2020 National Electrical Code answer references, plus access to JCR's digital mock exam app. Digital access starts at checkout; the booklet ships the same business day.
JCR writes these questions from real-world exams, so you see the question styles and formats the SFD exam uses and know where you stand before you sit for it.
The sample tests cover residential wiring methods, load calculations, service sizing, grounding and bonding, and the other NEC rules specific to single family dwellings. Use the booklet with a JCR Exam Preparation Manual, or on its own as a readiness check.
Want the manual and videos too? The Single Family Dwelling Exam Preparation Bundle includes this mock exam.
NC SP-SFD exam: what you can bring
The NC SP-SFD exam is open book, including the NASCLA guide. Bring your own copies of these three books. They are the only references allowed in the room:
- 2020 National Electrical Code (NFPA 70)
- 2013 National Fire Alarm and Signaling Code (NFPA 72)
- NASCLA Contractors' Guide to Business, Law, and Project Management, North Carolina Electrical 14th edition
None of these books comes with this mock exam. The SP-SFD exam also covers the NC Electrical Contractors Licensing Law, the Board's 21 NCAC 18B rules and the NASCLA guide.
Details, including the permanent-tabs-only rule, are in the 2026 NCBEEC/PSI Examination Information Handbook.
