You're right, the NEC doesn't specify a minimum number of receptacles for general commercial spaces like doctor's exam rooms, unlike dwelling units. Your typical spacing of 12 feet is a good design practice for general use, but it's not a code requirement.Here's a breakdown of things to consider: NEC Focus

The NEC primarily focuses on safety, not convenience. It ensures you don't overload circuits, use appropriate wiring methods, and protect against shock hazards. Convenience (like having enough receptacles) is generally left to the designer and the client's needs.

Commercial vs. Residential

Residential spaces (dwelling units) do have requirements for receptacle spacing (typically 6' along walls), but these don't apply to commercial spaces.

Meeting the Client's Needs

Since the doctor only wants 2 receptacles, the key is to document that you've discussed the implications with them and that this decision is intentional. If they understand that 2 receptacles might limit their options for equipment placement and future needs, and they're okay with it, then you've fulfilled your responsibility.

Potential Issues & Recommendations (Things to discuss with the doctor)



Long Extension Cords

Fewer receptacles can lead to the use of extension cords, which can be a safety hazard (tripping, overloading, damage to cords). Are they OK with this?

Equipment Needs

Discuss what kind of equipment they plan to use in the exam rooms, now and in the future. Even a "general doctor" might have equipment like: Electronic blood pressure monitors EKG machines (depending on their practice) Computer/Laptop Printer Exam lights Wall mounted equipment (nebulizer, etc.)

Future Changes

Re-wiring exam rooms later to add more receptacles will be disruptive and expensive. It's almost always cheaper to add more receptacles during the initial construction.

Accessibility (ADA)

Ensure the placement of the receptacles complies with ADA guidelines for reach ranges, even if the primary concern isn't directly related to accessibility. This is a good practice and will help ensure compliance if the building's use ever changes.

Dedicated Circuits

Consider if any specific equipment will require a dedicated circuit to avoid overloading general purpose circuits. This would require additional receptacles, which might be useful even if the doctor doesn't initially think they need them.

Grounding

Ensure all receptacles are properly grounded to protect against electrical shock.

Documentation is Key



Written Confirmation

Get written confirmation (email, change order, etc.) from the doctor stating they understand the limited number of receptacles and accept the potential implications.*

Plan Review

Clearly mark the location of the receptacles on your electrical plans for review and approval.

In summary:

You're correct that the NEC doesn't mandate a specific number of receptacles in this situation. However, it's your responsibility to advise your client about potential downsides and document their decision. Explain the possibility of needing more receptacles in the future and ask if there are any anticipated uses that would require dedicated circuits. If the doctor insists on only two receptacles per room after you've explained the potential issues, get it in writing and move forward. Flag for review
