Eaton B-line 303012RHC Nema 3R Panel Enclosure 30x30x12

Product Description

The EATON B-LINE 303012RHC is a NEMA 3R rated heavy-duty steel panel enclosure designed for surface-mount electrical installations. Measuring 30 inches high by 30 inches wide by 12 inches deep, it provides a weatherproof housing for electrical controls, distribution equipment, and related components. The NEMA 3R rating means the enclosure is built to resist falling rain, sleet, and external ice formation, making it suitable for outdoor and semi-protected indoor locations. Licensed electricians and electrical contractors install this type of enclosure in industrial, commercial, and utility applications where a durable, corrosion-resistant housing is required.

This enclosure is used in residential, commercial, and light industrial settings where outdoor or weatherproof electrical panel housing is required. Typical applications include metering sections, disconnect housings, control panel builds, and distribution equipment installations. The surface-mount design allows direct wall or structure attachment without recessed cutouts, simplifying installation on concrete, steel framing, or wood structures.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements and local codes. De-energize all circuits before opening or mounting the enclosure. Ensure mounting surface is plumb and capable of supporting the enclosure weight and all internal equipment loads. Seal all conduit entries with appropriate weatherproof fittings to maintain the NEMA 3R rating after installation.
