Square D QOC30U QO Load Center Panel Cover Assembly

Replacement panel cover assembly for Square D QO load centers, designed specifically for 30-space configurations and finished in gray for indoor use. The QOC30U family includes surface-mount versions (QOC30US) as well as flush-mount variants (such as QOC30UF and QOC30UFWG); these covers are intended to cap 30-space QO load centers and protect the interior while providing a clean, finished appearance. The flush-mount variant QOC30UFWG is listed at a footprint of 31.06 inches high by 15.44 inches wide with a depth of 0.7 inches, aligning with the standard QO panel cover dimensions for that installation style, while the surface-mount QOC30US serves indoor, surface-mounted installations. These covers are UL Listed and CSA rated for use with Square D QO circuit-breaker load centers and are compatible with QO-type breakers. In terms of electrical configuration, QOC covers are designed for QO load centers with convertible mains in the range of 100–225 A, making them suitable for a variety of residential and light commercial installations that employ 30-space QO panels. This cover assembly is typically used to replace a missing or damaged panel cover, restoring safety and enclosure integrity inside an indoor environment without changing the existing breaker lineup.
