Grounding Bushing - 1-1/4 in trade size, insulated throat, lay-in lug
SKU: MC-1.25GRBUSH
1-1/4 in grounding bushing for rigid conduit or IMC, used to bond and protect conductors at threaded raceway entries. Common listings for this size use an insulated throat and a lug for copper or aluminium grounding conductors; verify wire range and approvals before ordering.
What this product is for
This grounding bushing is used on 1-1/4 in threaded rigid conduit or IMC to provide a bonding connection and an insulated throat where conductors enter an enclosure or raceway termination.
Use for
- Bonding metal raceway to the grounding system
- Protecting conductor insulation at conduit entries
- Commercial, industrial, and service equipment installations using threaded conduit
Avoid for
- Non-threaded raceway unless the fitting is specifically rated for it
- Applications where the required conductor range or certification is unknown
- Corrosive locations unless the material and finish are confirmed for the environment
Best for
Electricians and contractors who need a 1-1/4 in trade size grounding bushing for standard rigid conduit or IMC bonding work and want an insulated throat with an integral grounding lug.
Installed in
Panels, switchgear, pull boxes, wireways, meter bases, and other enclosures where threaded conduit entries require bonding. Typical trade use is at service and feeder raceways, subject to local code and inspection requirements.
Why this product exists
A grounding bushing helps maintain bonding continuity and reduces the risk of conductor insulation damage at the raceway end. As a rule of thumb, electricians commonly select the bushing by conduit trade size first, then confirm the grounding conductor range, lug type, and certification. Actual suitability depends on the installation method, conductor size, and local electrical code.
Compared with similar products
Compared with a standard insulating bushing, a grounding bushing adds a lug for bonding. Compared with grounding locknuts or bonding locknuts, this style is commonly chosen where an insulated throat and a direct grounding conductor termination are needed. Listings found for similar 1-1/4 in products vary by body material, wire range, temperature rating, and approvals, so matching the exact part is important.
