1. What is the maximum allowable voltage drop for feeders in a
healthcare facility branch circuit serving life safety equipment per NYC
Electrical Code?
A) 1%
B) 3%
C) 5%
D) 10%
✔✔✔ANSW✔✔: B) 3%
Rationale: For life safety and critical branches in healthcare facilities, the NYC Electrical Code
(based on NEC 517) limits voltage drop to 1.5% for feeders and 1.5% for branches, totaling 3%
maximum for feeders alone in critical applications.
2. In a NYC H+H facility, what color is required for the isolated ground (IG)
receptacles in patient care areas?
,A) Gray
B) Orange
C) Red
D) Blue
✔✔✔ANSW✔✔: B) Orange
Rationale: Isolated ground receptacles must be orange with a green triangle (or orange with a
green dot) to distinguish them from standard hospital-grade receptacles, per NEC 406.4(D) and
NYC amendments.
3. What is the minimum size copper equipment grounding conductor
required for a 100-amp feeder supplying a critical care branch panel in a
hospital?
A) #10 AWG
B) #8 AWG
C) #6 AWG
D) #4 AWG
✔✔✔ANSW✔✔: B) #8 AWG
Rationale: Based on NEC Table 250.122, a 100-amp overcurrent device requires an #8 AWG
copper equipment grounding conductor, regardless of upstream derating.
4. When installing conduit in a MRI room within an H+H facility, which
material is strictly prohibited due to magnetic interference?
,A) EMT
B) Rigid Steel
C) Aluminum
D) PVC
✔✔✔ANSW✔✔: B) Rigid Steel
Rationale: Ferrous metals (steel) are prohibited within the magnetic field zone of MRI equipment
because they can become projectiles and distort imaging. Non-ferrous materials like aluminum,
copper, or PVC are used.
5. What is the required transfer time for a Type 1 emergency system (life
safety branch) in a NYC hospital?
A) 10 seconds or less
B) 15 seconds or less
C) 30 seconds or less
D) 60 seconds or less
✔✔✔ANSW✔✔: A) 10 seconds or less
Rationale: NFPA 99 and NFPA 110 mandate that Type 1 essential electrical systems (hospitals)
must transfer life safety and critical branches to emergency power within 10 seconds of utility
failure.
6. Per NYC Electrical Code, what is the minimum clearance required for
electrical panels installed in corridors of a healthcare facility?
, A) 30 inches width, 36 inches depth
B) 36 inches width, 36 inches depth
C) 30 inches width, 42 inches depth
D) 36 inches width, 48 inches depth
✔✔✔ANSW✔✔: A) 30 inches width, 36 inches depth
Rationale: NEC 110.26 requires working space of 30 inches width and 36 inches depth (or 36
inches if over 150V to ground) for electrical equipment. NYC amendments do not reduce this for
healthcare.
7. What type of overcurrent protection is required for the critical branch of
a hospital emergency system?
A) Standard thermal-magnetic breakers
B) Fully rated, selectively coordinated breakers
C) Fusible switches only
D) GFCI breakers only
✔✔✔ANSW✔✔: B) Fully rated, selectively coordinated breakers
Rationale: NEC 517.30 and 700.32 require full selectivity coordination for emergency and critical
branch overcurrent devices so a fault on a branch circuit does not trip upstream feeders serving
life safety equipment.
8. In a patient care vicinity, what is the maximum distance a hospital-
grade receptacle can be located from a patient bed?
