®NEMA rating matched to the environment
Outdoor, wash-down and corrosive environments each call for a different NEMA rating, and enclosures here get specified against the actual site condition rather than a default indoor-rated box.

Enclosures & NEMA Boxes
Custom electrical enclosures built to the NEMA rating a site's environment demands, sized to the equipment going inside.
Enclosures & NEMA Boxes
Custom electrical enclosures built to the NEMA rating a site's environment demands, sized to the equipment going inside.
Enclosures rated and sized for your equipment
Sized to the actual equipment
Combiner, disconnect and monitoring hardware get measured and fitted before fabrication, avoiding the field modifications a generic catalog enclosure often needs.
Certified for inspection
Enclosures carry the UL listing and labeling an inspector checks, so a custom fit doesn't come at the cost of code compliance.
No field modifications, correct NEMA rating
Stop field-modifying a catalog enclosure
Custom sizing fits the actual equipment from the start, avoiding cutting and drilling in the field.
Match NEMA rating to the real environment
Enclosure rating gets specified against actual site conditions, not assumed from a standard spec sheet.
Your questions, answered.
What NEMA rating does an outdoor solar enclosure typically need?
Outdoor solar enclosures commonly use NEMA 3R at a minimum for rain and weather protection, with NEMA 4 or 4X specified where washdown, dust, or corrosion is a concern. The right rating depends on the site's actual environment, including coastal salt air or heavy dust. Matching the rating to real conditions is better than defaulting to a catalog box.
Can an enclosure be custom-sized for non-standard equipment?
Yes, enclosures can be built to the dimensions the equipment inside actually requires rather than forcing gear into a stock box. Custom sizing avoids the field modifications that a catalog enclosure often needs. It also keeps clearances and knockouts appropriate for what is being installed.
Do custom enclosures carry the same certifications as catalog products?
Custom-fabricated enclosures can be built and certified to the same standards inspectors expect, so a custom size does not mean skipping certification. Confirm the applicable listings for the enclosure and its NEMA rating before ordering. That keeps the enclosure ready for inspection instead of raising a red flag.
