New Hampshire-Electrical Online Practice Test

These are actual questions from our online practice test.

We have included a question from each chapter of the test. Every question will be multiple choice. The answers are not included with the sample.

Sample Questions

# Chapter Title Question
1 Electrical, Wires, Cables and Raceways For most 120/240V systems using cables of adequate ampacity, voltage drop is not a concern unless cable lengths are well over a hundred feet.
2 Electrical, Heaters, Conductors, Bonding and Voltage 120/240 V single phase system with single black-red-white conductors (installed in single conduit) select "single set of conductors", 120/208 V 3 phase system with 2 conductors per phase and neutral (installed in 2 parallel conduits) select _________ conductors per phase in parallel", dc system with 3 positive and 3 negative conductors select "3 conductors per phase in parallel".
3 Electrical, Connections, Panel Boards and Grounding What clearance is required for the front of a 208/120 panel?
4 Electrical Systems, Cables, Wires and Electrical Sign Installation

A sign can be used as a pull box or junction box for adjacent signs, outline lighting systems, or floodlights that ______________..

5 Electrical Branch Circuits Dual Element Fuse =
6 Motor Controls and Occupancies The smallest bonding conductor permitted for pool equipment is No.  ___ AWG.
7 NEC and Electrical Equipment

If a 60 gallon water heater has a name plate rating of 4500 watts and is fed by a 2 wire, 240 volt circuit, what is the minimum size NM cable conductors that can be used?

8 Electrical Transmission Lines and Communication Lines A messenger that is effectively grounded throughout its length will have the same clearance from the communications facilities that are required for a neutral conductor meeting regarding Rule ___________ in reference to fiber optic supply.
9 Electric Power Conditioning and Mechanical Electrical Lamp pole for exterior use is located 20 ft. away from the building. What type of raceway would be used?
10 Conduits, Voltmeters, Ammeter and Ohmmeter What color are the wire for pins 2 and 5 on an RJ13 jack?
11 Protected Premises, Fire Alarm Systems and Fundamentals

Every low power radio transmitter will automatically repeat alarm transmission at intervals not exceeding __ seconds until the initiating device is returned to its normal alarm condition.

12 Alarm Inspections, Testing and Maintenance How often shall detectors be tested?
13 Emergency Alarm Communication Systems, Control Functions and Interfaces What do smoke detectors mounted in the air ducts of HVAC systems do?
14 Electrical Miscellaneous, Conductors, Wires, Panels, EMT and Currents The maximum secondary conductor length permitted by the NEC from a transformer to a main breaker in an office building is _________ ft. The rules in Sec. 240.4 require you to protect all conductors against over current in accordance with their ampacities as specified in Sec. 310.15.
15 Photovoltaics The _____________ is the creation of voltage or electric current in a material upon exposure to light. The effect is directly related to the photoelectric effect, though they are different processes. When the sunlight or any other light is incident upon a material surface, the electrons present in the valence band absorb energy and, being excited, jump to the conduction band and become free.
16 Mathematics, Calculations and Formulas A store building 50 ft x 60 ft uses florescent lighting fixtures for interior. If each fixture is to illuminate 60 sq ft, how many light fixtures will be installed?
17 Safety, Dig Alert and Asbestos - Code of Federal Regulations, Title 29, Part 1926

For all Class I jobs involving the removal of more than ____________ linear or 10 square feet of thermal system insulation or surfacing material; for all other Class I jobs, where the employer cannot produce a negative exposure assessment pursuant to paragraph (f)(2)(iii) of this section, or where employees are working in areas adjacent to the regulated area, while the Class I work is being performed, the employer shall use one of the following methods to ensure that airborne asbestos does not migrate from the regulated area:

18 Labors, Employees, Contractors, Insurance and Safety What is required to be worn by employees and contractors at all times to minimize forces transmitted to the head, neck, spine, from falling objects?
19 Bid Preparation, Basic - Blueprint Reading and Plans The notice to owner contained in a contract, informs the customer of _________________.
