Bridgeport Fittings Insulated Grounding Bushing with Lug, Malleable Iron

The Bridgeport Fittings Insulated Grounding Bushing with Lug is built in malleable iron to deliver a secure, code-compliant ground path at conduit terminations. This family of grounding bushings is available in sizes ranging from 1-1/2" through 4", giving contractors a consistent, dependable fitting across smaller branch circuits up to larger feeder and service conduit terminations. Designed for installations where rigid or intermediate metal conduit enters a box, panel, or enclosure, this bushing pairs an insulated throat with an integral grounding lug so electricians can protect conductor insulation and complete a reliable bonding connection in a single fitting. The malleable iron body stands up to the mechanical demands of conduit runs, making it a practical choice for electricians who need a dependable grounding solution on commercial and industrial jobs, regardless of which size in the range is selected.

Key Features

  • Trade Size Range: Available from 1-1/2" through 4", covering both smaller branch conduit runs and larger industrial and commercial feeder and service installations.
  • Durable Construction: Malleable iron body resists impact, corrosion, and mechanical stress for long-term reliability on the job site across every size in the range.
  • Insulated Throat: An insulated liner shields conductor insulation from abrasion and damage as wires pass through the conduit termination point.
  • Integral Grounding Lug: A built-in lug provides a dedicated attachment point for a bonding or grounding conductor, simplifying installation and helping ensure a solid ground connection.
  • Secure Conduit Termination: Malleable iron threads engage the conduit end firmly, helping keep the bushing and grounding connection in place under vibration and mechanical stress.
  • Combined Insulation and Grounding: Integrating insulation with a grounding lug in one fitting reduces the number of separate components needed at each conduit termination.

Bridgeport Fittings BPF385 – Frequently Asked Questions

1) What trade sizes does the Bridgeport Fittings insulated grounding bushing with lug come in?
Two trade sizes are offered on this malleable iron grounding bushing with lug: 1-1/2 inch (part 385) and 4 inch (part 390). Order by the trade size of the conduit you are terminating, not the conductor size.
2) Will this grounding bushing thread onto rigid metal conduit and IMC?
Yes. The bushing is made for rigid and intermediate metal conduit (IMC) terminations where the conduit enters a box, panel, or enclosure. The malleable iron body threads onto the conduit end and holds under vibration.
3) Do I still need a separate insulating bushing if I use this one?
No. This fitting combines an insulated throat with the grounding lug, so one part protects conductor insulation at the conduit end and gives you the bonding attachment point. That is what the Insulated with Lug configuration means.
4) Where does the bonding conductor attach on this bushing?
An integral lug on the body is the attachment point for the bonding or grounding conductor. You land the wire directly on the bushing lug, so no separate grounding clamp or lug is needed at that termination.
5) Is a plain insulated bushing enough, or do I need the version with a lug?
If the conduit only needs conductor protection at the throat, a plain insulated bushing does the job. Use this Insulated with Lug version when you also have to run a bonding jumper from that conduit termination, such as at service entrance, feeder, and panelboard terminations where the raceway has to be bonded to the enclosure.
6) Can I standardize on one grounding bushing across branch circuits and large feeders in a building?
Within this line, yes. The same insulated-with-lug malleable iron fitting spans 1-1/2 inch through 4 inch trade sizes, so smaller branch conduit and larger feeder or service terminations use the same fitting type and the same install method throughout the facility.
7) Is a malleable iron grounding bushing better than plastic or die cast for an industrial job?
Malleable iron is the choice where the termination takes impact and mechanical stress, which is why this bushing is aimed at commercial and industrial work. Insulated plastic bushings protect conductors but give you no metal body for the lug connection or the abuse of a large feeder run.
