Crouse-Hinds GLL8DC – Frequently Asked Questions

1) What trade sizes does the Crouse-Hinds GLL grounding bushing come in?
The Crouse-Hinds zinc die cast insulated throat grounding bushing runs the full conduit range: 1/2 inch (GLL1DC), 3/4 inch (GLL2DC), 1 inch (GLL3DC), 1-1/4 inch (GLL4DC), 1-1/2 inch (GLL5DC), 2 inch (GLL6DC), 2-1/2 inch (GLL7DC), 3 inch (GLL8DC), 3-1/2 inch (GLL9DC) and 4 inch (GLL10DC). Order by the trade size of the conduit or the threaded hub you are landing on, not by the knockout diameter.
2) Do I still need a plastic bushing if I use a grounding bushing on the conduit?
No. The GLL series has the insulated throat built in, so one fitting does both jobs: it protects the conductor insulation where the wire leaves the raceway and it gives you a lug to land the bonding jumper. Adding a separate insulating bushing on top of it is redundant.
3) Which grounding bushing do I use on a 4 inch service conduit entering a switchgear enclosure?
For 4 inch conduit the part is GLL10DC, the largest size in the Crouse-Hinds zinc die cast insulated throat grounding bushing range. Service entrance raceways are exactly where a grounding bushing earns its place, since the concentric and eccentric knockouts common on gear enclosures need a bonding path back to the ground bus rather than relying on the locknut alone.
4) Will a grounding bushing thread onto EMT, or do I need rigid conduit?
The GLL bushing is a threaded fitting, so it lands on rigid or IMC conduit ends and on the threaded ends of set screw or compression EMT connectors. It does not thread directly onto bare EMT, since EMT has no threads on the tube itself. On an EMT run you put the connector through the knockout first, then the grounding bushing on the connector threads inside the enclosure.
5) How do I match a grounding bushing to conduit size when the box knockout is a different size?
Size the bushing to the conduit or connector thread, never to the knockout. If a 1 inch conduit lands in an oversized knockout, you still order GLL3DC for the 1 inch thread and use reducing washers to close the opening. Getting this backwards is the most common reason a grounding bushing arrives and will not thread on.
6) Is a zinc die cast grounding bushing okay outdoors or in a damp mechanical room?
Zinc die cast is the body material here, and it holds up in wet and corrosive spots where a plain steel fitting rusts at the threads. Crouse-Hinds calls out moisture and environmental protection for commercial and industrial use, which covers rooftop runs, parking structures and mechanical rooms. For heavy chemical exposure most electricians step up to a malleable iron or PVC coated fitting instead.
7) What is the difference between a grounding bushing and a bonding locknut?
A bonding locknut bites into the enclosure metal to bond a knockout and sits on the outside of the box. A grounding bushing like the GLL goes on the conduit end inside the enclosure, protects the wire at the throat, and gives you a screw lug so a bonding jumper can run to the ground bus. On service raceways and where concentric knockouts break the bonding path, the jumper and lug is the approach most inspectors expect to see.
8) Can I standardize on one grounding bushing line across a whole facility?
Yes, and that is the practical argument for the GLL series: one family covers 1/2 inch through 4 inch, all zinc die cast with the same insulated throat, so a maintenance stockroom carries one line instead of mixing brands by size. Stock the sizes your branch circuits and feeders actually use, typically 1/2 inch (GLL1DC) and 3/4 inch (GLL2DC) in volume with the larger feeder sizes in ones and twos.
