UL 508A is the standard for Industrial Control Panels — the governing certification for control panel enclosures that integrate components such as breakers, relays, indicators, and controllers into a listed panel assembly. A UL 508A certified panel shop is licensed to engineer, assemble, and list custom control panels to this standard. For commercial and industrial projects requiring a listed panel assembly — as required by most local building codes and electrical inspections — a UL 508A panel shop is a prerequisite for the work. Heatizon is a UL 508A certified panel shop, one of very few radiant heating manufacturers with this certification.
