With our exam prep program you will be able to go into an examination with confidence knowing exactly what types of questions to expect, what reference materials are used, and how the questions are written and phrased. Familiarity with these code and text book questions is a must to pass your state examination.

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. Begin to Prep At Home with an immediate digital download!

Important Notes:

  • Refer to your candidate information bulletin provided by the State or the testing agency to get a complete list of which reference books can be taken into your exam.
  • “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 !!!)

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.

Since we know that you are going to have to answer questions from specific code book sections, we focus our effort to develop exam prep materials for those sections. This allows you to focus your time and effort on these topics, and not misuse your time simply reading through the code book.


Study topic area: “Calculations”

    1. What is the power consumption of a electrical circuit that operates on a source voltage of 120 Volts, and has a resistive load value of 40 Ohms.
      1. 480 watts
      2. 360 watts
      3. 220 watts
      4. 115 watts

Correct answer is: 2

Article Reference is: Ohms law states: P = (E x E)/R = (120×120)/40 = 360 Watts “Be prepared to calculate Ohms law questions on your test. Very important to quickly access the formula wheel.” Ohms law is easy, if you have the formulas written down, therefore, write down the formulas on your blank sheet of paper BEFORE you begin your exam.

Study topic area: “Conductors”

    1. What would be the derated value for a #8 AWG conductor (insulated with THHN) given that the conductor is to be run through a raceway at an ambient temperature of 40 degrees C? This conductor is only one, of a total of six current carrying conductors in that raceway.
      1. 55 amperes
      2. 40 amperes
      3. 30 amperes
      4. 25 amperes

Correct answer is: 2

Article Reference is: See references and corresponding adjustments below:
Table 310.15(B)(16) for ampacity of the conductor, 55 amps.
Table 310.15(B)(2)(A) for correction factor, 0.91.
Table 310.15(B)(3)(A) for adjustment factor, 80%.
Therefore, 8 Awg THHN = 55a x 0.91 x 0.80 = 40 amperes.
“For multiple conductors and temperature you MUST derate the ampacity of each conductor”

Study topic area: “Motors”

    1. An overcurrent protection device must have a minimum rating of amps for a 1.5 HP, single-phase, alternating current motor, operating on 115 volts.
      1. 18 amperes
      2. 20 amperes
      3. 23 amperes
      4. 26 amperes

Correct answer is: 3

Article Reference is: Table 430.248 “This single-phase table is not used as much as the three-phase motor Table 430.250. Be familiar with both tables for your exam.”

Study topic area: Services”

    1. Calculate the total farm load of dairy ranch building that has a common service that supplies the following separate branch circuit loads:

      •Load 1 is 18,000 volt-amps

      • Load 2 is 16,000 volt-amps

      • Load 3 is 10,000 volt-amps

      1. 100 amps
      2. 152 amps
      3. 200 amps
      4. 304 amps

Correct answer is: 2

Article Reference is: Table 220.103 “Calculations are shown below:”
1st load: 18,000 VA x 100% = 18,000 VA
2nd load: 16,000 VA x 75% = 12,000 VA
3rd load: 10,000 VA x 65% = 6,500 VA
Net computed load = 36,500 VA / 240 V = 152.1 amperes

Our students are provided with hundreds of questions like the ones shown above, that are developed specifically to cover each and every subject area for the computer programs that we offer. Why wait?
