Overview of industrial control panels
Industrial control panels (ICPs) are defined by the National Electrical Code (NEC) Section 409.2 as an assembly of two or more power circuit components, control circuit components, or any combination of power and control circuit components. These components are typically switches, terminal blocks, contactors, motor drives, transformers, overcurrent protective devices and the like.
Similar to other industrial equipment, ICPs can be evaluated as open type or enclosed. Open-type equipment is ultimately installed in an enclosure before being put into service. Enclosed ICPs can be rated for indoor use or any type rating, such as 3R, 4, or 12. In addition, these can be certified for use in classified areas, e.g., hazardous locations.
As a global leader in certifying ICPs, we maintain close relationships with authorities having jurisdiction (AHJs). This partnership allows control panel manufacturers to label either mass-produced or custom-built ICPs without needing our examination of each design. Often called the Panel Shop Program, it offers unique flexibility for panel manufacturers. The program covers certification for U.S. and Canadian markets. Also unique to this program is the required training for panel shops that want to be a part of the program.
Industrial Control Panel Shop Program
Our Industrial Control Panel Shop Program (ICP Program) allows control panel manufacturers who custom-build or mass-produce ICPs to apply the UL Marks for the U.S. and Canada at their factories. Our ICP program makes it convenient to receive a UL certification while allowing maximum flexibility in panel design. When regulators, specifiers and end-product certifiers see the familiar UL Mark, they can be confident that the panel has met the certification requirements. View pricing or request a quote.
ICP Program benefits include:
- Increase your competitive advantage — Offer your customers UL certified general use, industrial machinery, elevator control, service equipment, air conditioning and refrigeration equipment, fountain control, irrigation equipment, crane and flame control, and marine use panels and bid on jobs that specify UL certified ICPs.
- Cover all requirements — Our ICP Program covers proper component usage, enclosure environmental ratings, wiring and motor protection, safety markings, and conformance to the National Electrical Code (NEC) and Canadian Electrical Code (CEC).
- Greater efficiency — help to minimize red-tagged panels at the job site, along with the resulting delays and extra cost.
- Widespread acceptance — Benefit from the widespread acceptance of the UL Mark by regulatory authorities in every jurisdiction in the U.S. and Canada.
- Increased component sourcing — UL and CSA International have a formal component acceptance agreement that permits acceptance of specific components for use in end products, including ICPs. This agreement gives our customers even more flexibility when sourcing components because covered CSA certified components can now be used in UL certified panels in addition to UL certified components already permitted under the scope of the ICP program.
- Training and consulting — We share our expertise through technical training, workshops and advisory services focused on the needs of ICP builders. Attend one of our custom panel builder workshops and hear from the technical experts who can help you “build safety in” while meeting the requirements set for you by regulators and your customers.
The UL 508A Industrial Control Panel Shop Program is a part of UL’s General Coverage programs, which offer control panel manufacturers flexibility to apply UL Certification Marks to a wide range of industrial control panel designs. The control panel manufacturer’s level of knowledge and quality control measures are important elements of these programs. Control panel manufacturers initially entering the Industrial Control Panel Shop Program are required to complete mandatory training on the UL 508A industrial control panels Standard and then maintain qualified staff knowledgeable of the requirements of the Standard. Each manufacturing location must maintain at least one UL 508A qualified manufacturer technical representative (MTR) on staff who can effectively interpret and accurately apply the requirements of the UL 508A industrial control panels Standard. Details for qualifying an MTR can be found in the UL subscriber bulletin and on the examination description page.
We provide certification of industrial control panels to UL 508A, the Standard for Industrial Control Panels. The third edition of UL 508A becomes effective on July 1, 2020. So, understanding and applying current requirements is essential to meet your customer needs and market demands.
While training is not required for the new UL 508A third edition, we are here to support your transition to the new edition. Watch the complimentary on-demand webinar: UL 508A third edition update, hosted by John Kovacik, principal engineer. He will review the changes from UL 508A second edition to UL 508A third edition.
If you are interested in training, we do have other virtual training options available for industrial control panels UL 508A and short circuit current ratings. If you have any questions, please fill out the contact us form.
