517.30 C(3) states

The wiring of the emergency system in hospitals shall be mechanically protected. Where installed as branch circuits in patient care areas, the installation shall comply with the requirements of 517.13(A) and (B). The following wiring methods shall be permitted:​

So the first sentence states that all emergency wiring shall be mechanically protected but the second sentence makes it only apply to patient care areas. We are currently designing a pharmacy so the question is what wiring method is required.

You can use any of the wiring methods listed in 517.30(C)(3) 1 through 5.

The first sentence stands on its own, and applies to any portion of the emergency system:

Code: 
The wiring of the emergency system in hospitals shall be mechanically protected.

The second sentence provides additional requirements for branch circuits in patient care areas:

Code: 
[B]Where installed as branch circuits in patient care areas,[/B] the installation shall comply with the requirements of 517.13(A) and (B).

Basically the second sentence says you can't use PVC conduit (or other non-metallic wiring methods) for patient care branch circuits.
 
I read that to say that branch circuits that are installed in patient care areas must, in addition to the mechanical protection, meet the requirements if 517.13(A)&(B).

Just curious is the pharmacy located in a hospital?

A pharmacy by itself would not be a healthcare facility by the definition in Article 517.

Health Care Facilities. Buildings or portions of buildings
in which medical, dental, psychiatric, nursing, obstetrical,
or surgical care are provided. Health care facilities include,
but are not limited to, hospitals, nursing homes, limited
care facilities, clinics, medical and dental offices, and ambulatory
care centers, whether permanent or movable.

Not all branch circuits in patient care areas are part of the emergency system.

Correct but all branch circuits in Patient Care Areas must comply with 517.13(A) & (B).

You can omit the wire EGC but the raceway or cable sheath be recognized in 250.118, see Exception NO 2 of 517.13(B)
