  1. According to NEC Article 100, what is the definition of 'continuous load'?

    Answer: A load where the maximum current is expected to continue for 3 hours or more

    A continuous load is defined as a load where the maximum current is expected to continue for 3 hours or more.

  2. NEC Section 110.14 addresses electrical connections. Which of the following is required?

    Answer: Terminals for more than one conductor must be identified for that use

    NEC 110.14 requires that where terminals are designed to accept more than one conductor, they must be identified for that use on the equipment or in its instructions.

  3. What NEC term applies to live parts that can be approached or touched by a person without using tools to remove guards or barriers?

    Answer: Exposed (as applied to live parts)

    Exposed, as applied to live parts, means capable of being inadvertently touched or approached nearer than a safe distance without intentional use of tools or barriers.

  4. Under NEC 110.26(F), dedicated equipment space above a panelboard must extend from the top of the equipment to the structural ceiling or to a maximum height of:

    Answer: 25 ft above the equipment

    NEC 110.26(F)(1) requires the dedicated equipment space to extend from the top of the electrical equipment up to the structural ceiling or 6 m (25 ft) above the equipment, whichever is lower.

  5. The NEC defines 'identified' (as applied to equipment) to mean:

    Answer: Recognizable as suitable for the specific purpose, function, use, environment, or application

  6. According to NEC 110.3(A), what must the AHJ examine or test when determining the suitability of equipment?

    Answer: Mechanical strength, wire-bending space, arcing effects, heating effects, and classification of installation

    NEC 110.3(A) lists multiple evaluation factors including mechanical strength, wire-bending space, arcing effects, heating under normal and fault conditions, and suitability for the classification of installation.

  7. Under NEC Article 100, a 'feeder' is defined as:

    Answer: All circuit conductors between the service equipment or source and the final branch-circuit overcurrent device

    A feeder consists of all circuit conductors between the service equipment (or other supply source) and the final branch-circuit overcurrent protective device.
