Description

Hubbell CFB10G55E Recessed Concrete Floorbox

Overview

The Hubbell CFB10G55E is a recessed concrete floorbox designed to house 8 or 10-gang electrical configurations, providing a clean and protected termination point for power and data cabling within a concrete slab. With a 5.5-inch depth of pour, this floorbox is engineered for new concrete installations where robust cable management and access are critical for commercial or industrial environments. It ensures that connections remain protected from foot traffic, debris, and potential damage, maintaining system integrity.

Compatibility

This floorbox is designed for use with standard 8-gang and 10-gang electrical boxes and associated conduit fittings. It accommodates a rectangular cover plate, allowing integration with various floor box cover systems. Specific compatibility is with Hubbell's range of floor box covers and internal mounting hardware designed for this gang configuration and pour depth.

Installation Notes

Installation requires setting the floorbox into the concrete formwork prior to pouring. Ensure the top flange is flush with the finished concrete surface to allow for proper cover installation. The 5.5-inch pour depth dictates the minimum slab thickness required. Verify local electrical codes for proper grounding and wiring practices within the floorbox.
