You are right. The issue is that you have paragraph (1) followed by an exception that itself has three conditions. The numbering should have resumed with (2) and not (4). Care to submit a suggestion for an errata? I don't know how to do that, but I am sure the NFPA web site has the process.

Manual transfer switch that connects power from a branch other than critical?

Dang, sleem highlighted it and all, still blew right past me.:slaphead:
I missed it too.
So if we read it literally, it seems to say we don't have to back up the heating if there is elevator service (since elevator service is numbered as an exception).
Obviously not the intent.
Dang MS word and their auto numbering.... I can never get what I want out of it either.....
Aside from numbering, I see also number.5 has nothing to do with equipment branch as in 517.44(B).

Looking at 517.35 as a guide, the exceptions should have been (a), (b), (c) instead of (1),(2),(3). That's probably why the numbering is off.
Some very odd changes to this section for nursing homes and limited care facilities. For one thing, referring to figures 517.42 (a) and (b), the "Critical Branch" is gone, and is now apparently called the "Equipment Branch".
So number 5 seems to refer to something that no longer exists in the new code??
However, 517.44(A) refers to the equipment branch, and 517.44(B) refers to the critical equipment branch. What the heck does that mean?

My guess is that in 517.44(B), the word critical got left in by mistake, and instead of "critical equipment branch", it should just say "equipment branch" which would match 517.44(A).
Also, I think #5:
"Additional Illumination, receptacles, and equipment shall be permitted to be connected only to the critical branch."
did not get revised along with the revision from calling the "critical branch" the "equipment branch".
I think it should say:
"Additional Illumination, receptacles, and equipment shall be permitted to be connected only to the equipment branch."

locally here since the incident with the nursing home HVAC during the storm this last summer in Florida.
The PA. Department of Health is requiring that all nursing home HVAC systems be included on the critical branch for these types of health care facilities.
I would think this is an attempt to move the code in that direction
I was also told that health care facilities are moving away from defining there life safety branch and critical branches as emergency.
