  1. When installing an isolated power system, the maximum total length of the branch circuit conductors on the secondary side of the isolation transformer is:

    Answer: 50 feet

    NEC 517.160(A)(3) limits the length of secondary conductors of an isolated power system to 50 feet to minimize distributed capacitance that degrades isolation.

  2. A health care facility generator set used for the essential electrical system must be capable of picking up full load within:

    Answer: 10 seconds

    Per NEC 517.30 and NFPA 110, the alternate source for a health care facility Type 1 EES must be capable of supplying power within 10 seconds of failure.

  3. Which NEC 517 requirement applies to receptacles located in anesthetizing locations?

    Answer: They must be part of an isolated power system

    NEC 517.160 requires that receptacles in anesthetizing locations be powered through an isolated power system to reduce shock and ignition hazards.

  4. In a hospital, the life safety branch and critical branch must be kept independent from each other and from:

    Answer: All other wiring systems and each other except where permitted by code

    NEC 517.30(B)(2) requires that life safety and critical branch wiring be kept entirely independent of all other wiring except where specifically permitted.

  5. Which of the following patient care areas requires a special protection system per NEC 517 due to the presence of flammable anesthetics?

    Answer: Flammable anesthetizing location

    NEC 517.60 covers flammable anesthetizing locations, which require special hazardous location wiring methods due to the risk of anesthetic gas ignition.

  6. What does the green indicator light on a line isolation monitor in an isolated power system indicate?

    Answer: The system is operating safely with low hazard current

    A green indicator on the LIM means hazard current is below the alarm threshold, indicating the isolated power system is functioning correctly.

  7. Under NEC 517.19(C), a patient care area that uses therapeutic high-frequency electrical equipment must have receptacles that are:

    Answer: Connected to an isolated power system and hospital-grade

    NEC 517.19(C) requires that areas using high-frequency electrical equipment have isolated power systems and hospital-grade receptacles to prevent interference and shock hazards.
