Arc Flash Label

[Electriman]

Hi Friends,

Based on NFPA 70E 130.5 arcflash lables need to be updated every five years. But on the lable information requirement, there is no place for the date that Arcflash study is done. How is an electrician supposed to know that this information is up-to date?

I might be wrong and I need to mention the date but I dont see anywhere in the code to mandate mentioning the date? Am I missing something?

Thanks,

I did a google search of arc flash labels and many, but not all, had the date and name of company that did the analysis.

I saw some of them have it there. But what I am saying is it required?

What 70E says

What 70E says

This is what 2015 70E says must appear on equipment labels:

Electrical equipment such as
switchboards, panelboards, industrial control panels, meter
socket enclosures, and motor control centers that are 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:
(1) Nominal system voltage
(2) Arc flash boundary
(3) At least one of the following:
a. Available incident energy and the corresponding
working distance, or the arc flash PPE category in
Table 130.7(C)(15)(A)(b) or Table 130.7(C)(15)(B)
for the equipment, but not both
b. Minimum arc rating of clothing
c. Site-specific level of PPE

No date on label required but most if not all of the labeling software that I'm aware of has the option of applying a date.

Which says basically that if review is needed every 5 years that review must be driven by documentation kept on site somewhere and not on information on the label.
Otherwise you would have to replace the label every five years even if the descriptive information did not change.

does the label need to have all this information or can you use minimum arc label requirement that reads Refer to NFPA 70e. Just Asking. we do alot of multi family and minimal commercial not enough to make or need labels.

If you are following NFPA 70E-2015, then you need to have on the label the minimum information shown. That being said NFPA 70E-2015 also states "The owner of the electrical equipment shall be responsible for the documentation, installation, and maintenance of the field-marked label."

1 10.16 Arc-Flash Hazard Warning
Electrical equipment, such as switchboards, switchgear, panelboards,
industrial control panels, meter socket enclosures,
and motor control centers, that are in other than dwelling units,
and are likely to require examination, adjustment, servicing, or
maintenance while energized, shall be field or factory marked
to warn qualified persons of potential electric arc flash hazards.
The marking shall meet the requirements in 110.21(B) and
shall be located so as to be clearly visible to qualified persons
before examination, adjustment, servicing, or maintenance of
the equipment.

In short you do not need a label in housing.

Also 110.21(B) Marking

( B) Field-Applied Hazard Markings. Where caution, warning,
or danger signs or labels are required by this Code, the labels
shall meet the following requirements:
The Code requires that equipment be marked with the identification
of the manufacturer by name or appropriate trademark, the
equipment ratings, and hazard warnings. The markings must be
located where they will be visible or easily accessible during or
after installation. The marking must not be handwritten and must
have adequate durability to survive the environment. Only information
that is variable or subject to change is permitted to be
handwritten. See Exhibit 110.10.

So a label printed on paper on your inkjet or laser printer is not acceptable.
