Reliance PBN30 30 A Power Inlet

This non-metallic power inlet box provides a 30 A, 125/250 V AC connection point for a portable generator. It mounts on an exterior wall and feeds a transfer switch inside the building. The ABS enclosure carries a NEMA 3R rating for outdoor use.

Who this suits and who it does not

Homeowners installing a manual transfer switch for backup power will find the L14-30 connector matches common generator cords. Installers needing a metallic enclosure, a higher amperage rating, or a different NEMA configuration should select another model.

Deciding specification — 30 A L14-30 rating

The NEMA L14-30P inlet and 30 A current rating determine whether the box matches your generator cord and transfer switch. Verify that both the generator receptacle and the switch inlet are rated for 30 A at 125/250 V before purchasing.
