517 Dental Offices

[NClark]

Dental care offices have become a vague, convoluted topic specifically the requirement for hospital grade devices OR NOT. The wiring methods need a redundant ground per 517.13 but do the actual receptacles within the treatment rooms need to be hospital grade? Looking for code references

See the definition of Patient Bed Location then look at 517.18(B), 517.19(B) and 517.61(C)(2)

None of those references help. They reference patient bed areas. Patient Bed by definition is "The location of a patient bed, or the bed or procedure table of a CRITICAL CARE SPACE. Dental offices fall under Basic Care Category 3 spaces.

Exactly, that's the reason I gave you those references. THOSE ARE THE ONLY AREAS HG RECEPTACLES ARE REQUIRED.

ah gotcha. Then we can agree they are not required within basic dental treatment rooms.

Pretty much but 517.61(C)(2) can throw a monkey wrench in to the equation. It will send you to 517.60(B)

I need to mention that some dental chairs have a tag that calls for a HG receptacle and that would mean you would have to provide one for the chair alone.
