Stainless Steel PanelUL-logo.pngOur panel fabrication shop at Nationwide Control Solutions is UL 508A & 698A certified. We design, assemble and install UL certified panels and can bring existing control panels up to UL safety standards.

What is UL 508A?

A UL 508A certification is the Standard for Safety of Industrial Control Panels in ordinary locations in accordance with the National Electrical Code, NFPA 70.  The standard provides guidelines to panel fabricators on various issues including proper component selection, wiring methods, and calculation of short circuit ratings. The UL listing mark on an industrial control panel provides evidence of third party certification and is typically something that electrical inspectors look for. The UL 508A mark shows that the panel complies with an acceptable safety standard.

What is UL 698A?

Panels relating to hazardous locations require use of UL Listed barriers to make the circuit extensions intrinsically safe. A UL 698A certification is the Standard for Safety of Industrial Control Panels Relating to Hazardous Locations. This standard covers panels intended for installation in ordinary locations with intrinsically safe circuit extensions into Class I, II, and III, Division 1 and 2; and Class I, Zone 0, 1 and 2 hazardous (classified) locations installed in accordance with Article 500, 504, and 505 of the National Electrical Code, NFPA 70.

Why UL?

UL has developed more than 800 safety standards. The UL mark is one of the most recognized, accepted and trusted symbols in the world. It ensures that an independent laboratory has tested samples of products to safety requirements and conducts periodic checks of manufacturers' facilities. The UL mark provides assurance that steps have been taken in the interest of safety.

In addition to Underwriters Laboratory certifications, all of our burner management and combustion control systems are designed around the requirements of NFPA-85/86/87 as well as our client's insurance carrier requirements.
