The HUBBELL PB3IEBCA is an interior base cover designed for use with 2-channel and 3-channel raceway wiring systems. It provides a finished, protective covering over the base of surface-mounted raceway runs, keeping conductors concealed and secure. This component is part of a modular raceway system commonly installed in commercial and light industrial environments where exposed surface wiring must be organized and protected. Electricians working on structured wiring layouts, office retrofits, or partition wall builds will find this cover fits directly into the Hubbell raceway system lineup.
This base cover is suited for interior applications where raceway channels run along walls or baseboards. It is designed to work with 2-channel and 3-channel configurations, making it appropriate for installations that separate power and low-voltage or data conductors within the same raceway assembly. Typical use cases include office buildouts, classroom wiring, and other commercial interior environments where a clean, code-compliant surface wiring solution is required.
Designed as an OEM-style interior base cover replacement for Hubbell 2-channel and 3-channel surface raceway systems used in commercial interior wiring installations.
Installation is performed by a licensed electrician following applicable NEC requirements for surface metal or non-metallic raceway systems. De-energize all circuits in the affected raceway run before removing or installing covers. Ensure the base section is fully secured to the mounting surface before attaching the cover to maintain proper conductor protection and system integrity.
