Working on a panel dealing with UL labels

Are components that are not UL listed or UL recognized ever be used in a UL listed panel?

APPENDIX B – (informative) – USE OF COMPONENTS NOT UL LISTED OR RECOGNIZED IN
INDUSTRIAL CONTROL PANELS

Supplement SA is the shopping catalog. :)

SUPPLEMENT SA – Deleted
On July 28, 2017, and March 19, 2018, a proposal to remove Supplement SA from UL 508A and relocate
the information therein to a UL LLC website achieved and maintained consensus. In accordance with this
decision by STP 508A, the information in Supplement SA may now be found by clicking the link below.
This website will be maintained by UL LLC, any changes or questions about this website should be
directed to the UL Principal Engineer for UL 508A.
