Patient care spaces under NEC 517

NEC Article 517 covers health care facilities, including medical and dental offices, wherever patients are examined or treated. Its best known rule is the redundant ground in patient care spaces: the equipment grounding path is provided two ways. The rules are planned from the start of a build-out, because they decide how the wiring is run.

• Patient care spaces identified on the plans
• Wiring methods that provide the redundant ground
• Panel schedules that mark the patient care circuits

Equipment circuits from the sheets

Imaging units, sterilizers, compressors, vacuum pumps and dental chairs each come with an installation sheet naming the voltage, the circuit size and whether the circuit must be dedicated. We wire from those sheets, and the compressor and vacuum room gets its own circuits and the clear space its equipment needs.

Power that has to stay on

A practice that cannot cancel a day of patients for an outage, or that keeps vaccines or samples cold, often puts those loads on standby power. The design professional and the authority having jurisdiction decide how a system is classified, and we wire it to match.

Working in an open practice

Work in an open clinic is planned around the schedule: noisy work and shutdowns after hours, dust kept out of treatment rooms, and no circuit opened without knowing what equipment is on it. Every shutdown is agreed with the practice manager in writing.

Permit and inspections

Inside the city limits the permit goes through the City of San Antonio Development Services Department under the 2023 NEC, adopted effective May 1, 2025. The inspector looks at the patient care circuits, the panel labeling and the working space NEC 110.26 requires in front of each panel. A suite converted from another use can also trigger a change of occupancy review.

What goes wrong, and how we prevent it

The usual problems are equipment chosen after the circuits were roughed in, patient care areas missed on the plans, and panel schedules that do not say what feeds what. We get the equipment sheets before rough-in, confirm the patient care spaces with the design, and leave a panel schedule that names each room and each piece of equipment.
