UL-508A certification for industrial control panels is a requirement in most jurisdictions and a standard many OEMs voluntarily choose to follow. There is a common misconception that a UL-508A certified panel shop can certify any panel they build. However, panels must also be designed to UL-508A standards to be certified.
It’s no surprise that certified draft control products save significant time and money while reducing the risk of shock, fire, equipment damage and even explosion. But what does it really mean when you buy a control panel labelled “UL listed?”
There are two dark secrets which most panel buyers don’t know about, but need to:
- A UL sticker on the outside may mean that only the enclosure is listed, not the entire assembly.
- ‘Certified panel shop’ does NOT mean ‘certified panel!’
Kinda sneaky, right? How does this happen? And what can you do to ensure safe electrical operation of your control panels?
UL508A Panel vs. UL Listed Control
The two are different. Very different.
A UL508A Panel Listing allows a panel shop to build controls that comply with UL508A safety design guidelines. In this scenario there is:
- No installation manual,
- No verification of functionality, and
- No required testing of PLC software for safety; only for functionality
The panel shop applies a UL508A sticker to the product and frequently, that’s enough to pass off the system as ‘certified.’ It’s a common and dangerous mistake to assume that all components on the inside are also UL listed.
In contrast, a UL Listed Control means the manufacturer builds an additional controller that meets safety design guidelines AND functionality as described in the UL standards to which it is listed. Installation manuals and testing/verification of any software and functionality are MANDATORY, and all parts are certified.
A technicality of UL508A
Install epson printer driver windows 10. In a UL508A panel, parts must be listed or recognized for the panel’s intended use, and the panel must comply with certain requirements, including:
- Wire-bending radius inside the control panel
- Appropriate interrupting capacity ratings
- Use of UL-listed or UL-recognized components
- Adherence to the latest national electric codes (finger-safe terminals, contact points)
- Best wiring practices to ensure safety and functionality
- Proper separation of devices and terminals
- Dimensions and separation between penetrations to the control panel as well as proper sizing
Most panels are NOT certified
‘Certified shop’ does NOT mean ‘certified panel.’ It’s important to understand that UL-certified panel shops are NOT required to make only UL-certified panels. This isn’t always communicated to the panel buyer, and discount panels have worked this to their advantage quite nicely.
Non-certified panels do have a place in the market, clearly. In fact, most shops sell about 80 percent of their inventory as non-certified. That’s O.K., as long as the buyer knows to ask the shop whether or not the panel is certified.
Manuel Haro, CEO and director of sales for Accurate Controls ABB describes this as a “don’t ask, don’t tell” mentality.
Buyers can expect to pay approximately 10 percent more for a UL508A certified panel over a panel of similar construction. So naturally, most people opt for the lower-cost option. However, as the one ultimately responsible for safety, you need to understand that the UL508A label is just that… a label. It’s well worth diving deeper to see what you’re really buying.
You really need to verify that each panel component is what UL calls “Listed” or “Recognized” for the specific application. That’s the only way to make sure the system as a whole is will operate in a safe and effective manner.
Baked-in safety for all components
Certification to UL508A does not mean you can build to or meet any other standard. For example, nowhere is it implied that a UL508A panel can be considered or certified to UL 378 standard for draft equipment!
Therefore, ALL mechanical draft equipment and controllers, including Motor Control Centers, Switchboards, Panel Boards and Draft Controllers, require separate and unique UL certifications.
The EBC 31 Modulating Pressure Controller is a good example of a fully certified mechanical draft controller that was designed to comply with the strict safety guidelines of UL508A as well as UL 378, baked in right from the start. As you can see in the following listing report for the EBC 31, these controllers are in sync with UL’s latest listing standards for draft/motor controllers:
If you’re not sure whether your entire panel assembly is certified, or just a part of it, ask us. The revised UL standards are confusing, but you are not alone. Our engineers can help you understand the new control standards for draft equipment and how they may impact the success of your overall project. Not ready to talk yet?

Tips for buying control panels
Now that you know the dark secrets about UL508A and UL Listed Control Panels, here are a few important considerations when choosing your control panel vendor. Do NOT buy a control panel for your project unless it is:
- Made from UL-listed components recognized for their specific application,
- Built according to UL standards, and
- Verified through onsite inspections for adherence to the standard
Other considerations worth investigating include the vendor’s track record for having delivery issues, long lead times, and/or slow response times. Also, investigate whether they actually make products, or are they using outside vendors and fabricators?

Making the effort to confirm that what’s inside your panel has the same UL rating as what’s outside will keep you out of trouble; save time, money and risk; and improve the overall quality of your projects.

UL 508A certification is an industrial control panel directive, which is sought by electrical inspectors. The UL 508A Listing Mark on an industrial control panel provides evidence of third party certification to the municipal inspection authority and to the purchaser of the panel. A UL 508A Listing Mark shows that the panel complies with an acceptable safety standard.
![Ul 508a exam Ul 508a exam](/uploads/1/3/7/3/137392751/548048220.jpg)
The official definition of an industrial control panel, according to UL, is 'an assembly incorporating two or more pieces of industrial control equipment or related control circuit devices, provided with interconnecting wiring and terminals for connections in the field. To allow the installer to properly install the panel in accordance to National Electrical Code (NEC) and other codes, electrical ratings and instructions are to be clearly explained on the panel.'
Installation of a control panel can be completed in two ways: in an enclosure as 'enclosed type' equipment, or arranged onto a mounting panel as 'open type' equipment. For 'open type' equipment, the assembly is installed in an enclosure provided by others, or at the installation site. Any of the outdoor enclosures or cabinets manufactured by Purcell Systems that carry the UL 508A Listing Mark would be classified as “enclosed type”, and complies with the applicable requirements for outdoor panels noted in the UL 508A standard.

UL 508A Certified Enclosures
Benefits of selecting an enclosure or cabinet that carry the UL 508A certification include:
- UL 508A certification provides the inspection authority and your customer evidence that the control panel complies with nationally recognized safety standards. These standards ensure public safety, and provide assurances that the electrical control panel is compliant with national and local electrical codes.
- Manufacturers that carry the UL 508A certification are subject to periodic unannounced inspections of their facilities by UL personnel. Through periodic audits of the manufacturers, UL can insure the manufacturer continues to meet the UL requirements for 508A certification.
- For a control panel to carry the UL 508A Listing Mark, the panel must contain only UL recognized and listed components. The UL Mark on a component means that UL has evaluated and tested samples of this component and has concluded that they meet the UL requirements. This protects the quality and integrity of the enclosure and provides guarantee of safe performance.
