Crouse-Hinds GLL10 – Frequently Asked Questions

1) Will the Crouse-Hinds GLL10 grounding bushing fit 4 inch rigid conduit?
Yes. The GLL10 is a 4 inch trade size insulated grounding bushing made for rigid and IMC conduit terminations. It threads onto the conduit end, so the conduit has to be threaded rigid or IMC, not EMT.
2) What does an insulated grounding bushing actually do at a panel entry?
Two jobs at once. The insulated throat keeps the conductor insulation from being chewed up where the wires leave the conduit, and the lug on the body gives you a place to land a bonding jumper so the equipment grounding path stays continuous through the raceway. On the GLL10 that is a 4 inch rigid or IMC termination into a panelboard or enclosure.
3) Is the GLL10 bushing metal or plastic bodied?
Malleable iron body with an insulated throat. The metal body is what carries the bond; the insulating liner is only at the conductor opening. A fully nonmetallic bushing would not give you a grounding path.
4) Do I still need a bonding jumper with the Crouse-Hinds GLL10, or is the bushing enough?
The bushing is the connection point, not the whole path. It gives you a secure lug to terminate the equipment grounding conductor or bonding jumper to the enclosure or ground bar. The jumper wire and any lugs on the panel end are separate items you supply.
5) What is the exact part number to order for the 4 inch Crouse-Hinds insulated grounding bushing?
Crouse-Hinds GLL10. One trade size only, 4 inch, so there is no size or finish option to specify on the order.
6) Will malleable iron hold up in a damp industrial plant room?
The GLL10 body is malleable iron chosen for strength and corrosion resistance in demanding installation environments, which is why it is commonly specified for industrial raceway work. For heavy wash-down or chemical exposure, confirm the plating against your spec for that area.
