Are you required by NEC to provide ground fault protection to a dental chair
As a general rule I don't think so.Are you required by NEC to provide ground fault protection to a dental chair
There is a tiny faucet and a tiny drain at the dentist chair to flush ones mouth. Would that be considered as a sink ?

I think not. The "6' from sink" rule is based on most portable tools and appliances having 6' long cords. The hazard comes from dropping such an item into a sink full of water. This concept would not apply to a dentists chair.There is a tiny faucet and a tiny drain at the dentist chair to flush ones mouth. Would that be considered as a sink ?

I thought the 6 foot rule was that most adults have about a 6 foot wingspan. If most cords are 6' maybe the rule should be 12 feet?
Then why is there a requirement that any receptacle within 6' of a sink have GFCI protection? I think it is because you might drop a non-faulty device into the sink.Being able to reach the water with a faulty device in your hand is not the hazard. The hazard is the faulty device itself.
The ones I've seen sure look like sinks to me. Valve, faucet, water comes in, goes into drain? What else would it be?

I suspect that it turns into a faulty device.And what happens when you drop a non-faulty device into the sink ?

Correct, but it can energize the water if the sink has standing water in it.But just because something falls in the sink doesn't mean it automatically becomes faulty.

There is no valve, and there is no faucet. There is a tube through which water flows into the spit bowl.The ones I've seen sure look like sinks to me. Valve, faucet, water comes in, goes into drain? What else would it be?
And exactly how is the spit bowl that is attached to the dental chair going to have standing water? If it were to clog up somehow, the dental hygienist would turn it off and ask you to get out of the chair before the bowl overflows onto your shirt.. . . if the sink has standing water in it.
Me not know. I haven't been to dentist a lot, but also never had to spit in a bowl or sink, they always had used suction to extract whatever may need removed.There is no valve, and there is no faucet. There is a tube through which water flows into the spit bowl.

The dental chair is listed as a complete assembly. We don't get to isolate parts of it and apply the NEC rules to those parts. I'll continue to submit that that spit bowl thing is not a sink, in the context of the NEC rule concerting GFCI protection for receptacles.
