Why do patient-care spaces use the specified redundant grounding path?
- ATo permit neutral current on metal raceway
- To improve grounding reliability for patient-care equipment
- CTo replace all branch overcurrent protection for the special occupancy and condition described
- DTo eliminate equipment grounding conductors
Why B is correct
Patient-care spaces require an insulated equipment grounding conductor plus an approved metal wiring-method path where specified, improving grounding reliability in a sensitive environment.
