Arc Flash Label Requirement Clarification

[R_Roc]

Is there a boundary that Arc Flash Labeling is exempt, like anything under 240V. In NFPA 70E 2012 it stated anything under 240 V was exempt from labeling, but this was removed in the 2015 edition. Is there another document/standard that can shed any light?

The only boundary where items don't have to be labeled are areas that fall outside of the labeling requirements listed in NFPA 70E-2015, Art. 130.5(D). One area that comes to mind is motor connection boxes (peckerheads). Otherwise a label is required on "Electrical equipment such as switchboards, panelboards, industrial control panels, meter socket enclosures, and motor control centers that in other than dwelling units and that are likely to require examination, adjustment, servicing, or maintenance while energized shall be field marked with a label containing all the following information:...."

What we provide for our clients, in addition to the custom labels from the arc flash study, are a generic type of label for use on equipment that is exempt from analysis per IEEE 1584-2002. These labels look very similar to our custom labels and accomplish several objectives:
1. Provide information on shock hazard and any PPE required.
2. By having even the exempt equipment labeled it removes the question of is this equipment exempt or was it missed when the study was performed?

We will apply these generic labels as much as possible when performing the data collection as we encounter the exempt equipment. It does take long to make the determination and apply the label. Many times there is a small transformer next to a 480V panel and then the 120/240 single phase or 208Y/120V 3 phase panel is next to that transformer.

So what equipment is actually exempt or can you reference the section of IEEE 1584?

Also what actual information are you providing on your generic labels since the NFPA 70E requires them to have specific PPE/boundary data which requires the study be completed?

Are you saying that you put generic labels on all 120/240 single phase and 208Y/120V 3 phase panels?
