Re: Article 110.16 Flash Protection marking
Even though the code only applies to new installations, it would be very responsible and diligent of you to go ahead and add the stickers or labels to existing equipment when servicing or making adjustments.
I understand that nobody pays any attention to this anyway, but don't let a lawyer find out you worked on the equipment and didn't bother to add the warnings after someone gets hurt down tohe road.
I was able to purchase very nice 4x6 stickers for about 79 cents a piece. I kept several dozen with me and stuck them on everything I touched. If anything, it made me feel better.

Re: Article 110.16 Flash Protection marking
I don't have any code text of any manner in front me right now, but for what it's worth I've had two electrical safety instructors from two different national training orgs tell me that we are NOT grandfathered from putting the arc flash warnings on ALL such equipment, new installation or not. I -think- some of that comes from 70E, not NEC.

Re: Article 110.16 Flash Protection marking
the wording of this requirement seems odd to me. the wording says the reason for the warning is to alert qualified persons to the risk.
would not a qualified person already know there is a risk? if he/she is qualified, than why would you need to warn them?

Bob,
That's why I think it's dumb too.
I have not reviewed the ROP or ROC's for that item, but I would suspect that it was a compromise between no label and a NFPA 70E label (lots of calculated detail).

Re: Article 110.16 Flash Protection marking
The original accepted proposal called for the cal/cm rating to be on the label, but that was changed to a generic label at the comment stage. When specific information was required, it made sense for this to be a field supplied and installed label, now with only a generic warning required, it would make more sense to have this a manufacturer supplied and installed label.

Arcing Flash Blast . . . The Other Electrical Hazard . . . by Ralph Lee . . .
Keep it simple . . .
NO ONE GETS HURT ! ! !
Owners of the equipment; At a minimum add a generic ARC FLASH HAZARD Label
Supervisors of "QUALIFIED" service personnel (direct employees or contract); Must advise their worker of the hazard level, flash boundary and PPE required to perform the work
QUALIFIED; A person familiar with the CONSTRUCTION, OPERATION and HAZARDS of the equipment involved.
Panelboards, MCC's, Switchgear; ABB, ITE, G&W, S&C, Siemens, Cutler Hammer, Square D, Allen Bradley, etc are constructed and operate differently depending upon their required system application.
At this point in time, manufacturers CANNOT add detailed hazard labels to their standard equipment, they do not know the available fault current at the installation location, or the trip curve characteristics of upstream protective devices.
In general; IEEE 1584 states that at service voltages of 240V or less, feed by a transformer rated 125 kVA or less, it is difficult to sustain an arc flash event . . . But it has occurred! From my hazard analysis experience these lower voltage high kVA fed devices will continue arcing for 15 minutes or more if ignited . . . This will most likely start the structure on fire!
Again, the number 1 priority is NO ONE GETS HURT!

Have the labels printed with your company name and phone number on them that way you get the service call for when something goes wrong owner doesn't have to go to phone book to find someone it is right there on the panel cover cheap advertising to say the least

Re: Article 110.16 Flash Protection marking
marinesgt0411 has a good solution.
If the Labeling Company has a contact number, Service Companies can use this as part of their work permit process. Equipment owners have identified and labeled the hazard, the Service Company can now specify PPE requirements to perform the work.
Labeling Companies need relevant system data, integrity and honesty.
Service companies need trust, integrity, honesty and "QUALIFIED" personnel to perform the work.
If lawyers are required, something in the protection path broke down . . .
