Bridgeport Fittings SGBS-388CL – Frequently Asked Questions

1) Can I install the Bridgeport SGBS-388CL grounding bushing without pulling the conductors out of the conduit?
That's the whole point of the split body. The SGBS-388CL is a two-piece insulated split grounding bushing, so it goes onto a conduit run that already has wire in it without disturbing the existing conductors. That makes it the fitting to reach for on retrofit, service, and maintenance work where a solid one-piece bushing would mean re-pulling the run.
2) Does the SGBS-388CL have a lug for the bonding conductor, or do I need a separate lay-in lug?
The lug is built in. The SGBS-388CL carries an integral aluminum grounding lug as the termination point for the bonding jumper, so no separate lay-in lug is needed. Body is steel, lug is aluminum.
3) Will a grounding bushing protect the conductor insulation where the wire leaves the conduit?
Yes on this one. The Mighty-Rite SGBS-388CL has an insulated throat, so the conductors bear on an insulating surface rather than a metal edge as they pass through the fitting. That's what keeps a 3 inch pull from scoring the jacket on a large conductor.
4) What do I order to bond an existing 3 inch rigid conduit entering a panelboard?
For an existing run, specify Bridgeport Fittings part SGBS-388CL, the 3 inch Mighty-Rite insulated split grounding bushing, then supply your own bonding jumper sized to the circuit for the aluminum lug. Typical uses are panelboard and equipment grounding, service entrance grounding, and general rigid or IMC bonding in commercial and industrial work.
5) Is the Bridgeport SGBS-388CL a solid bushing or a split bushing, and when would I choose the solid one instead?
It's the split version. Use the split bushing when the conduit is already installed and wired. If you are roughing in new work and the conduit end is open with no conductors pulled, a one-piece insulated grounding bushing threads on just as well and is the simpler choice. The split body exists to save you a re-pull, not to improve new construction.
6) Is a steel-body bushing with an aluminum lug alright for a commercial install, or should I look for all-steel?
The combination is how Bridgeport builds this one: steel body for the mechanical duty of a 3 inch conduit termination, aluminum lug as the conductor termination. It is intended for everyday commercial and industrial electrical work. If your job spec calls out a specific lug material for the bonding conductor, match the spec, since the lug here is aluminum.
