Automatic Transfer Switch Owner’s Manual 9
Fault Current Label
See
Figure 2-6
. A Fault Current Identification Label is
provided in the bag containing the unit Owner’s Manual and
transfer switch manual operating handle. The 2017 NEC
requires that the short-circuit current rating of the transfer
equipment, based on the type of overcurrent protective
device protecting the transfer equipment, be field marked on
the exterior of the transfer equipment. For NEC compliance,
verify the required short-circuit current rating of the transfer
switch before installation.The completed label provides the
local AHJ (Authority Having Jurisdiction) with the information
he or she may require during inspection.
Apply the label to the exterior of the transfer switch
enclosure. Use a pen to fill in the required information, and
then cover the label with the clear protective decal.
