Im just curious, do others interpet this to mean all EXISTING panels, or just new construction?? Ive been told that its just for new panels (panels under the 2008 nec) and not the old ones. How are other areas enforcing this??

The NEC never applies retroactively.
shall be field marked to warn qualified persons of
potential electric arc flash hazards.
A Qualified Electrician will know the danger without the markings
But the 70E does, thats where the labeling requirement goes "Retroactive"
But that is not what the man asked is it?![]()
I don't think that you will find many, if any units of government that have adopted 70E as a code, so this will not be enforced by the inspector or AHJ.No, but I am guessing the OP isnt aware of the 70E labeling requirement.

There is no obligation to the installing contractor to provide the 70e marking unless called for in the construction documents. It is really the responsibilty of the owner. The only "enforcement will be by OSHA, insurance companies and who ever enforces the contract documents.
Brother,
If you are working in a plant, there is no question that OSHA requires the lables and that will apply to both new and existing equipment. My comment was just saying that outside of a contract document there is no requirement for an electrical contractor to provide the 70E required labels.
The NEC does require an arc flash warning, but only a generic warning. The rules in 70E require a specific warning with information about the incident energy and PPE that is required at that specific piece of equipment.NEC 110.16 REQUIRES the marking or labeleing of potential arc flash hazard on the electrical equipment. The reference to NFPA 70E is only a FPN to assist in determining the severity of hazard and the planning in the selection of the PPE to be used. Whether or not your jurisdiction adopts NFPA 70E, the warning is still a requirement per NEC.
