At Pinnacle Ozone, we are proud to be a UL-listed shop authorized to build and label control panels to the UL 508A standard. This designation reflects our commitment to safety, quality, and technical excellence in every panel we produce.
What is UL 508A?
UL 508A is the Standard for Industrial Control Panels, developed by UL Solutions (formerly Underwriters Laboratories), a globally recognized safety science company. This standard governs the construction, wiring, and component selection of industrial control panels used to operate equipment such as pumps, compressors, conveyors, and other machinery.
By following UL 508A, manufacturers ensure that their panels are built to prevent hazards like fire, electric shock, and equipment failure. The standard covers topics such as:
- Component spacing and protection
- Short-circuit current ratings (SCCR)
- Labeling and wiring practices
- Enclosure types for specific environments
Compliance provides peace of mind for end users, system integrators, and inspectors, knowing that the panel was built to a national safety standard.
Who Enforces UL Standards?
UL 508A is published by UL Solutions, but enforcement comes through third-party UL-certified shops—facilities like Pinnacle’s, which have passed rigorous audits and maintain continuous adherence to the standard. These inspections verify that all control panels built under UL 508A follow specific construction and documentation requirements.
Unlike ISO certifications, UL 508A compliance doesn’t result in a single certificate for display. Instead, our UL listing allows us to label every qualifying control panel with an official UL mark, signaling that it has been built in a UL-inspected facility to meet safety standards.
Why UL 508A Compliance Matters
For our customers and partners, UL 508A compliance means:
- Safer operations: Panels are designed to mitigate electrical hazards and fire risks
- Streamlined inspections: UL labels speed up permitting and regulatory approvals
- International credibility: UL’s reputation as a global safety authority reinforces confidence
- Customization without compromise: Even our custom-built panels maintain full compliance
At Pinnacle, this standard empowers us to deliver control panels that aren’t just functional—they’re safe, reliable, and built to last.
A Commitment on Every Panel
Our compliance with UL 508A is a direct reflection of our team’s discipline and craftsmanship. Every panel that leaves our shop carries the UL mark, representing the expertise, safety, and quality our customers expect.
We don’t just meet the standard—we build by it.
