Square D B125 1-1/4 Inch Raintight Hub Qo Hom

Product Description

The Square D B125 is a 1-1/4 inch raintight hub designed for use with QO and HOM raintight load center products. This fitting creates a weatherproof conduit entry point on compatible raintight enclosures and load centers, maintaining the integrity of the enclosure against moisture intrusion. It is installed by licensed electricians during service panel installations or upgrades where outdoor or damp-location ratings are required. The B125 ships polybagged and is sold in a package quantity of 10 units, making it practical for contractors stocking common hardware for panel work.

The B125 is suited for residential and light commercial electrical installations where QO or HOM series raintight load centers are used in outdoor, garage, or other damp or wet-rated locations. Typical applications include exterior service panels, generator transfer switch enclosures, and other installations where conduit entries must maintain a raintight seal to meet NEC requirements for wet or damp locations.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the load center and verify the absence of voltage before beginning any work on the enclosure. Ensure the hub is properly seated and tightened to maintain the raintight rating of the enclosure. Do not overtighten or modify the hub fitting, as this may compromise the weatherproof seal.
