Industrial Control Panels for use in Hazardous Locations Panel Shop Program

The hazardous locations panel shop program is similar to the UL 508A panel shop program. It allows manufacturers who custom-build and/or mass-produce hazardous locations ICP's to apply the UL Listed Mark at their factories. The program makes it convenient to receive a UL Listing, while allowing the manufacturer to maintain flexibility in panel design.

What coverage is included?

United States and Canadian coverage for:

  • Class I, Division 1 (Explosion-Proof)
  • Class I, Division 1 (Purged/Pressurized Type X)
  • Class I, Division 2 (Purged/Pressurized Type Z)
  • Class I, Division 2 (Nonincendive)

The hazardous locations panel shop requirements are detailed in the UL Report issued at the completion of the project. The basic requirements include that the control panel shall comply with UL 508A and all components relied upon for hazardous locations protection are UL Listed, Recognized, or Classified for the applicable hazardous location.

Although our panel shop program only includes the types of panels shown above, other area classifications (like Class II) and other protection methods can be evaluated on a case-by-case basis.

What is the process for becoming a hazardous locations panel shop?

  • Obtain a UL508A Listing. If you don't currently have this Listing, go to "Become a UL Listed Panel Shop" for more information.
  • If you have a UL508A Listing now, request a HazLoc quote by going to http://my.home1.ul.com/portal/page/portal/PSR/HazLoc and follow the directions posted there (Choose NNNY as product category)
  • Once the quote has been accepted and the preliminary deposit (if required) has been received, a project will be opened and passed to the appropriate UL Engineer.
  • The Engineer will make contact to schedule a training visit at your facility.
  • After the training visit, a UL Report will be issued with all the requirements to build a UL Listed Hazardous Locations Panel.
  • A local UL field representative will conduct an Initial Production Inspection (IPI) on your first panel.
  • After the IPI, the manufacturer can apply the UL Listed Mark.
