Healthcare Basics
Why must the systems supporting a healthcare facility be available for constant use?
What is because many healthcare facilities operate 24 hours a day, 365 days a year?
Hospital essential electrical systems are divided into this many branches.
What are three branches?
This risk category represents the space where procedures create the greatest danger to a patient.
What is Category 1?
This system always provides conditioned power to critical loads, regardless of whether the load is supplied from normal or essential system feeders.
What is a UPS system?
In 1994, three regional building code organizations joined together to create this organization.
What is the International Code Council (ICC)?
According to NFPA 99 Annex A4.1, a lawn sprinkler system is classified as this risk category.
What is Category 4?
Normal and essential feeders should be physically separated primarily for this reason.
What is to prevent a single event from disrupting both feeders?
Wiring systems in wet procedure locations may be protected using this device, which limits fault current to not more than 6 mA.
What is GFCI equipment?
When redundant utility infrastructure isn't available, this is considered the most cost-effective way to provide redundant power.
What is on-site generation of redundant power?
This is one way CMS can enforce healthcare regulations.
What is denying Medicare or Medicaid reimbursement?
Article 517, Part II of the NEC applies to this type of space within a healthcare facility.
What are patient care spaces?
Running normal and essential feeders in the same trench or rack is considered this.
What is not good practice?
In a 3-phase isolated power system, the third conductor may be identified using this color combination.
What is yellow with a blue stripe?
When multiple generators are connected to a common bus, paralleling switches are used to accomplish this.
What is ensuring all generators are in phase with one another?
Because of diesel exhaust associated with peak shaving, this agency has expressed concern.
What is the EPA?
This is often used so healthcare facility subsystems can be taken offline for maintenance without affecting the overall system.
What is redundancy?
During a utility failure, a qualified person must perform these two actions to transfer back to normal utility power.
What is open the primary feeder switch and close the secondary feeder switch?
A healthcare installation requires a second ground-fault current path using an insulated copper conductor. This conductor must be identified by this color along its entire length.
What is green insulation?
Turbine engines have this amount of vibration compared with reciprocating engines because their shaft rotation is continuous.
What is less vibration?
This term describes the localization of an overcurrent condition so that an outage is restricted to the affected circuit or equipment.
What is selective coordination?
