  1. When connecting a 3-phase motor, swapping any two of the three phase leads will:

    Answer: Reverse the direction of motor rotation

    Swapping any two phase conductors on a 3-phase motor reverses the rotating magnetic field, causing the motor shaft to spin in the opposite direction.

  2. What is the correct procedure when installing a new circuit breaker in a live panel?

    Answer: Wear insulated gloves and use insulated tools with the main breaker off if possible

    Safe work practice requires insulated PPE and tools; turning off the main breaker eliminates shock risk from bus bars during breaker installation.

  3. A GFCI receptacle's 'Load' terminals protect:

    Answer: Receptacles wired downstream on the same circuit

    Devices connected to the LOAD terminals of a GFCI receptacle receive GFCI protection, extending protection to downstream outlets.

  4. When installing conduit in a concrete pour, which type should be used?

    Answer: PVC Schedule 40 or 80

    PVC Schedule 40 or 80 conduit is used in concrete encasement because it resists corrosion from the alkaline concrete environment.

  5. The ampacity of a conductor must be derated when more than three current-carrying conductors are bundled together because:

    Answer: Heat accumulates and cannot dissipate as effectively

    Bundled conductors share heat that cannot dissipate as quickly, reducing each conductor's safe current-carrying capacity.

  6. What type of wire connector is listed for use with both aluminum and copper conductors in the same splice?

    Answer: Purple wire nut (AL/CU listed)

    Wire connectors listed for AL/CU (aluminum/copper) use contain anti-oxidant compound and are rated for dissimilar metal connections to prevent galvanic corrosion.

  7. When installing outdoor receptacles exposed to weather, the cover must be rated:

    Answer: In-Use (extra duty) cover providing protection with or without a plug inserted

    NEC 406.9(B)(1) requires 'in-use' (extra duty) weatherproof covers for outdoor receptacles exposed to weather, protecting them even with cords plugged in.
