Are the installation instructions
part of the UL Listing?
Are all Listed products required
to have installation instructions?
Are installation instructions
reviewed by UL?
are considered to be a
part of the UL Listing.
The UL Standards for Safety used
to investigate products contain
specific requirements regarding
the content and appearance of the
instructions. Installation instructions
are not required to be
marked with the UL Mark, but
they are required to be provided
with the product bearing the UL
Mark. Some products are not required
to have installation instructions
when the National
Electrical Code contains all the
necessary installation requirements,
such as outlet boxes.
UL staff reviews the instructions,
both during the initial evaluation of
the product, as well as during the
continual Follow-Up Service at the
factories. The clarity of the instructions
is also reviewed.
