Question 1

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

Branch circuits serving patient care areas must have an effective ground-fault current path to quickly clear a fault and prevent electric shock to patients, staff, and visitors. This can be achieved by installing the circuit in a metal raceway system or a cable having a metallic armor or sheath assembly. The other options listed are not specifically required for patient care areas.

Question 2

Electrical installation criteria and wiring methods for health care facilities are ____ for a standard commercial or industrial project.

Accepted Answer

Health care facilities have more specialized electrical installation criteria and wiring methods due to the critical nature of their operations and the need for reliability and safety in patient care environments.

Question 3

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

A

Question 4

The branch circuit serving patient bed locations shall ____.

Accepted Answer

According to NEC 517.18(D)(2), branch circuits serving patient bed locations shall not be part of a multiwire branch circuit. Therefore, option C is the best choice. The other options are not directly related to the specific requirement.

Question 5

For essential electrical systems under ____, deletion of the time-lag intervals feature for delayed automatic connection to the equipment branch shall be permitted.

Accepted Answer

The answer of For essential electrical systems under ____, deletion...

Question 6

At least one of the receptacles of a patient bed location must be connected to (1) the normal system branch circuit as required or (2) a critical branch circuit supplied by ____ not associated with other receptacles at the same patient bed location.

Accepted Answer

The correct answer is a different transfer switch. This ensures that at least one receptacle at a patient bed location has an alternative power source in case of failure, enhancing reliability and safety in critical care areas.

Question 7

Ground-fault protection of equipment shall be provided for solidly grounded wye electric services of more than 150 volts to ground but not exceeding ____ volts phase-to-phase for each service disconnect rated 1000 amperes or more.

Accepted Answer

The answer of Ground-fault protection of equipment shall be provided...

Question 8

Critical care space served from ____ shall not be required to have circuits from the normal system.

Accepted Answer

The answer of Critical care space served from ____ shall...

Question 9

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

These requirements do not apply to freestanding buildings used as nursing homes and limited care facilities, provided that no surgical treatment requiring general anesthesia is offered.

Question 10

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

Accepted Answer

Solar panels and wind turbines are dependent on the availability of sun and wind respectively. A secondary service line may not provide a reliable power source. On-site generators can provide a consistent power source with the use of a prime mover such as diesel or natural gas engines.

Question 11

The space within a patient room no less than 6 ft beyond the bed's perimeter (in its normal location), and extending vertically no less than 71.2 ft from the floor is defined as the ____.

Accepted Answer

The space described in the question is defined as the patient care vicinity, which is the area around the patient where medical electrical equipment is likely to be used. This space is typically defined as extending 6 ft beyond the perimeter of the bed and 71.2 ft vertically from the floor. This is an important concept in medical device safety as it helps ensure that equipment used in patient care is properly designed and tested for use in these environments.

Question 12

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 life safety branch is designed to ensure that essential systems for life safety, such as lighting and receptacles, remain operational during a power outage by automatically switching to an alternate power source.

Question 13

Demand calculations for generator set(s) sizing shall be based on the following: (1) prudent demand factors and historical data, (2) ____, (3) Article 220 feeder calculation procedures, or (4) any combination of the preceding.

Accepted Answer

The answer of Demand calculations for generator set(s) sizing shall...

Question 14

Receptacles located within the rooms, bathrooms, playrooms, activity rooms, and patient care areas of designated pediatric locations shall be either be listed tamper resistant or shall ____.

Accepted Answer

Receptacles located within certain designated pediatric locations must either be listed as tamper resistant or employ a tamper-resistant cover. This is to prevent children from inserting foreign objects into the receptacles and potentially causing harm.

Question 15

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

Accepted Answer

Branch circuits serving special-purpose outlets or receptacles, like portable X-ray outlets, do not require service from the same distribution panel(s). The key consideration for these circuits is to ensure they meet the specific power quality and reliability requirements for the equipment they serve, rather than being tied to a particular distribution panel.

Question 16

The ____ of the essential electrical system shall supply power for lighting, receptacles, and equipment in a hospital.

Accepted Answer

According to NFPA 99, the life safety branch of the essential electrical system is responsible for supplying power to lighting, receptacles, and equipment in hospital settings. The critical care system, patient electrical network (PEN), and emergency patient care system are all additional branches of the essential electrical system that serve specific functions in medical facilities.

Question 17

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 procedure locations need to be identified in areas where the procedure involves intimate contact with the patient or staff. This ensures that the necessary precautions are taken to prevent slips, trips, and falls, as well as to maintain infection control. The other options are not directly related to the definition of wet procedure locations.

Question 18

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

Accepted Answer

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

Question 19

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

Accepted Answer

The critical branch includes important medical and lifesaving systems such as blood, bone and tissue banks, and critical care systems. Nurse call systems would also fall under this category as they are crucial for communication between patients and medical staff in emergency situations. The other options, such as ambulance parking area illumination, food storage areas, and accounting systems, are not directly related to critical medical care.

Question 20

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

The answer of Essential electrical systems for hospitals shall be...
