SEPCO 20BI4L Malleable Iron Insulated Grounding Bushing for Conduit Grounding

SEPCO 20BI4L Malleable Iron Insulated Grounding Bushing for Conduit Grounding

The SEPCO 20BI4L insulated grounding bushing delivers dependable equipment grounding at conduit terminations, built in durable malleable iron for demanding commercial and industrial installations. This SEPCO bushing combines a rugged malleable iron body with an insulated liner that shields conductor insulation from the raw metal edge of the conduit while maintaining a continuous, low-resistance bonding path to ground. It is available in trade sizes ranging from 1/2" through 4" to match a wide range of conduit runs, giving contractors a straightforward, reliable way to terminate raceways at panelboards, enclosures, and equipment housings where code-compliant grounding continuity is required.

Key Features

• Trade Size Range: Available in trade sizes from 1/2" through 4" to suit a wide range of conduit terminations.
• Durable Construction: Malleable iron body resists impact, cracking, and corrosion, holding up to the demands of commercial and industrial raceway installations.
• Insulated Design: An integral insulated liner separates conductor insulation from the metal edge of the conduit, reducing abrasion risk as wires pass through the bushing.
• Grounding Bushing Function: Terminates conduit runs while bonding the raceway to the equipment grounding system, supporting a continuous path to ground.
• Malleable Iron Body: The malleable iron construction provides the mechanical strength needed for secure conduit termination at panels and enclosures.
• Consistent Family Design: Every trade size in the 20BI4L lineup shares the same malleable iron, insulated-liner construction for uniform performance across a job.
