Reliance PBN50 50 A Power Inlet Box

This Reliance Controls inlet box provides a 50 A connection point for portable generators. It is built for homeowners and electricians installing a manual transfer switch. The ABS enclosure carries a NEMA 3R rating for outdoor surface mounting. cULus listing confirms compliance with North American safety standards.

Suits generator hookups needing a 50 A inlet

The CS6375 connector matches cords rated for 50 A at 125/250 V AC. Buyers whose generator cord uses a different plug style or a lower amperage rating should select a compatible inlet instead. Installations requiring a metallic enclosure or a higher environmental rating will need an alternative product.

50 A CS6375 connector decides fit

The inlet accepts only a CS6375 plug rated for 50 A service at 125/250 V AC. Verify the generator cord end matches this exact configuration before purchase. A mismatched connector will prevent a safe connection to the transfer switch.

Questions about this item

What mounting style does the PBN50 inlet box use?

The PBN50 uses surface mounting on an exterior wall, with the ABS enclosure rated NEMA 3R for outdoor exposure.

Which connector is on the inlet and how is it wired?

It has a CS6375 non-NEMA connector rated for 50 A at 125/250 V AC; the installer must match the generator cord to that exact configuration.

What long-term checks does the ABS enclosure need?

Inspect the ABS housing and gasket seals periodically for UV cracking or brittleness so the NEMA 3R rating stays intact over the five-year limited warranty period.
