Question 6

A system of feeders and branch circuits supplying power for lighting, receptacles, and equipment essential for life safety that is automatically connected to alternate power sources by one or more transfer switches during interruption of the normal power source is called a ____.

Accepted Answer

The system described here is commonly known as a Life Safety Branch, as it is designed to provide power for essential equipment related to life safety, such as emergency lighting, fire alarm systems, and exit signs, during power outages.

Question 7

Essential electrical systems for hospitals shall be comprised of ____ capable of supplying a limited amount of lighting and power service that is considered essential for life safety and effective hospital operation during the time the normal electrical service is interrupted for any reason.

Accepted Answer

Essential electrical systems for hospitals are typically comprised of three separate branches: the life safety branch, the critical branch, and the equipment branch. These branches ensure that essential services are maintained during power interruptions.

Question 8

Requirements in 517.40(C) through 517.44 do not apply to freestanding buildings used as nursing homes and limited care facilities, provided that ____.

Accepted Answer

Requirements in 517.40(C) through 517.44 are specific to healthcare facilities where patients are cared for and might require emergency medical procedures that involve electrical equipment. If a freestanding building used as a nursing home or limited care facility does not offer surgical treatment requiring general anesthesia, it is not subject to these specific electrical requirements, as the need for such stringent electrical safety measures (like those for operating rooms or critical care areas) is significantly reduced.

Question 9

The critical branch should include blood, bone and tissue banks, critical care systems, and ____.

Accepted Answer

The critical branch should include systems that directly support healthcare and patient care, such as blood, bone and tissue banks, critical care systems, and nurse call systems. Ambulance parking area illumination, food storage areas, and accounting systems are not directly related to patient care and are therefore not included in the critical branch.

Question 10

All branch circuits serving patient care areas shall be provided with a(n) ____ by installation in a metal raceway system or a cable having a metallic armor or sheath assembly.

Accepted Answer

All branch circuits serving patient care areas shall be provided with a (B) effective ground-fault current path by installation in a metal raceway system or a cable having a metallic armor or sheath assembly, as per NFPA 70: National Electrical Code. This ensures that in the event of a fault or surge, the current is safely and quickly conducted to ground, which reduces the risk of electric shock or electrocution to patients or staff.

Question 11

Wet procedure locations are the areas in a patient care space where a procedure is performed that is normally subject to wet conditions while patients are present, including standing fluids on the floor or drenching of the work area, where either such condition ____.

Accepted Answer

Wet procedures directly involve patient care and can lead to standing fluids or wet work areas, posing a risk to patients and staff. Choices B, C, and D are not relevant to the definition of wet procedure locations.

Question 12

Each patient bed location shall have a minimum of ____ receptacles.

Accepted Answer

The answer of Each patient bed location shall have a...

Question 13

An alternate power source can be ____ driven by some form of prime mover(s).

Accepted Answer

Solar panels and wind turbines are dependent on weather conditions and may not always provide a consistent power source. A secondary service line may be useful, but it would not be an alternate power source in itself. On-site generator(s) provide a reliable and consistent source of power that can be driven by a variety of prime movers such as diesel, natural gas, or propane.

Question 14

Branch circuits serving only special-purpose outlets or receptacles (such as portable X-ray outlets) do not require ____.

Accepted Answer

Branch circuits serving only special-purpose outlets or receptacles do not require service from the same distribution panel(s). However, they do require proper grounding and may require additional shielding depending on the specific application. They also do not require connection to an auxiliary or back up service unless required by local codes or regulations.

Question 15

Generator accessories, including but not limited to, the ____, electrically operated louvers, and other generator accessories essential for generator operation, shall be arranged for automatic connection to the alternate power source.

Accepted Answer

The transfer fuel pump is essential for generator operation as it ensures the continuous supply of fuel to the generator, which is critical for its functioning.
