Here is a small sample of our exam prep questions:

            Answer:  10 AWG.  Reference: NEC 2011 430.6(A), 430.22, 430.32, and Tables: 430.52, 430.248, 430.122 = 10 AWG.
  • Flexible cord immersed in or exposed to water shall be of a type for extra-hard usage, as designated in Table 400.4, and shall be a listed type with a ____ suffix?
            Answer:  Type SEW.  Reference: NEC 2011 680.56(B).
  • All 15 and 20 ampere, single-phase, 125-volt receptacles that are located within ___ feet of the inside walls of a pool shall be protected by a ground-fault circuit interrupter?
            Answer:  20 feet.  Reference: NEC 2011 680.22.

            Answer:  6 1/2 feet.  Reference: NEC 2011 110.26.
  • How many 15 amp branch circuits would be required for the general lighting load of a 2,150 square-foot dwelling living space?
            Answer:  Four circuits.  Reference: NEC 2011 Table 220.12 gives us 3 VA/sq-ft. So, 2,150 x 3 = 6,300 VA / 120 / 15 = 3.5 circuits, then size up to FOUR circuits.

Timed computerized exams can be difficult without preparation. Therefore, practicing sample tests, questions, answers, and code references repeatedly is critical for you to become an effective test taker. Our program has a Study and Review mode that allows you become familiar with the material prior to taking your sample tests. The Test mode allows you to gauge your understanding of the variety of topics that will be required to pass the state exam. Our questions are scrambled each time you test to simulate your actual state test experience. Your goal with our program is to get your test scores at home above 95% within the time limit of your exam.


The following reference materials are allowed in the examination center:

  • NFPA 70 National Electrical Code, 2011. National Fire Protection Association (NFPA), (800) 344-3555. www.nfpa.orgNEC-2011

Important Notes:

  • Candidates are responsible for bringing their own references to the examination center. Reference materials may be highlighted, underlined and/or indexed prior to the examination session. (Permanent tabs and highlighting is permitted. No notes !!!)
  • Although it is not recommended, the 2008 NEC Code Book will be allowed in the Examination room in lieu of the 2011. The examination questions are based on the 2011 code.

The trend has been over the last 5-10 years for the state examinations to be developed out of the code books that the State and the inspectors have adopted, rather than base questions on practical or hands-on experience. This is the main reason that our software program is so vital to your exam preparation. The majority of our customers are experts when it comes to installation and service for their specific trade, but are not proficient with timed computer examinations that are based on text and code book topics.  The time you spend with these sample questions and tests, familiarization with your code book, on your home computer will give you a good understanding of what to expect when you take the actual state exam. It’s great practice!
