NEC 2017 Article 700.12

[hhsting]

I have healthcare cosmetic eye procedure tenant space where patients are not capable of self preservation.

They are providing as emergency source portable power station Nexus PST3042. Engineer says it portable UPS and would be acceptable as emergency power source per NEC 2017 Article 700.12(C). I dont see portable UPS as acceptable in that section.

Can anyone here give there opinion as to this being acceptable emergency power source under NEC 2017 Article 700.12(C)?

700 is not the article for Healthcare it is 517

Ok i must be mistaking somewhere but NEC 2017 Article 700.12 does say healthcare occupancies where persons are not capable of self preservation to have the emergency sources. I dont follow

The only UPS's I've used for 700.12(E) compliance had a UL 924 listing and that one you posted didn't, and wouldn't have been able to last 90 minutes

What are they powering with that power supply?
How are they not capable of self preservation?

Well according to response letter your first question the portable power station is kept in base cabinet and always plugged in duplex outlet of wall. In event of outage doctor would plug in the portable power supply to the ups outlet. During procedure the doctor wears portable light pack head lamp that lasts 12 hours.

Second question response is that in procedure room patients performing cosmetic eye procedures. Anesthesia would be given that renders patients incapable of taking any action. Did not say anything after the procedure is done also there are no recovery rooms either.

It starts with Article 517, which tells you where & what needs emergency power, and when typical "unit equipment" is sufficient.

Emergency power must usually be per NFPA 110 (generators) or NFPA 111 (battery systems and UPS's and other methods of backup power).

And as Ron mentioned, NFPA 111 would probably require a UL 904 listing.

If emergency power is really required, I don't see any way a portable battery pack would comply. Nor would a battery powered headlamp.

A doctor is going to stop in the middle of a procedure and pull out a battery pack and move plugs for emergency power?

No way IMO.

Edit; 700 only applies where referenced by 517. NPFA 99 also has more detail on healthcare.
