Thomas & Betts 108 – Frequently Asked Questions

1) What conduit size does the Thomas & Betts 108 bonding locknut fit?
The 108 bonding locknut assembly is sized for 1 inch conduit and fittings, so it threads onto standard 1 inch trade size hubs and chase nipples. For any other trade size you need a different part number in the family, not this one.
2) What is the difference between a bonding locknut and a regular conduit locknut?
A standard locknut only clamps the fitting to the enclosure mechanically. A bonding locknut like the Thomas & Betts 108 is built for grounding continuity, so it maintains an electrical bond between the conduit or fitting and the box or panel while it holds the connection tight. Use the bonding type where you have to carry ground through the raceway connection; a plain locknut is fine where bonding is handled another way.
3) Can I use a bonding locknut to ground conduit at a panel instead of a grounding bushing with a lug?
The Thomas & Betts 108 is an assembly type bonding locknut, so it makes the bond through the threaded connection at the enclosure wall rather than through a screw lug. If your installation calls for a bonding jumper wire to be landed at the fitting, you want a grounding locknut with a lug instead, such as the Bridgeport Fittings 163-G Mighty-Bond zinc grounding locknut with aluminum lug or the Mighty-Bond insulated grounding locknut with aluminum lug.
4) What is the closest alternative to the Thomas & Betts 108 bonding locknut if I need a lug built into the fitting?
The Thomas & Betts 108 is a 1 inch bonding locknut assembly for grounding and bonding conduit connections at enclosures. If you want a grounding locknut that comes with a lug already attached for landing a bonding conductor, the Bridgeport Fittings 163-G Mighty-Bond zinc grounding locknut includes an aluminum lug, so the ground wire terminates directly on the fitting instead of at a separate lug or bonding bushing.
5) What is the Thomas & Betts part number for a 1 inch bonding locknut assembly?
Order it as Thomas & Betts 108. That is the single model offered for the 1 inch bonding locknut assembly, so there are no finish or material options to specify with it.
6) Which grounding locknut should I use where the connection needs to be insulated?
The Thomas & Betts 108 bonding locknut assembly is a bare metal bonding device that relies on metal-to-metal contact with the enclosure for continuity. Where the conductor entry needs an insulated throat, the Bridgeport Fittings Mighty-Bond insulated grounding locknut with aluminum lug is the alternative - it pairs the grounding lug with an insulated design, which is the usual choice when conductors would otherwise bear on a bare metal edge.
7) What is the difference between the Bridgeport 162-GI and 163-G Mighty-Bond grounding locknuts if the Thomas & Betts 108 is not the fit?
Both are Bridgeport Mighty-Bond grounding locknuts with an aluminum lug. The 162-GI is the insulated version, while the 163-G is the zinc grounding locknut with the lug and no insulating element. Choose the insulated one where conductors pass over the fitting throat; the zinc 163-G is the straightforward bonding substitute for a Thomas & Betts 108 application where you also want an integral lug.
8) Can a standard conduit locknut be used in place of the Thomas & Betts 108?
No. A plain conduit locknut only holds the fitting mechanically; the Thomas & Betts 108 is a bonding locknut assembly built to establish grounding continuity at the enclosure as part of a grounding system. If you need a bonding-rated device, stay with a bonding or grounding locknut such as the 108 or a Bridgeport Mighty-Bond grounding locknut with aluminum lug.
9) Where is a 1 inch bonding locknut typically used on a commercial job?
Typical uses for the 1 inch bonding locknut are panel and switchgear grounding, bonding conduit runs into enclosures, equipment grounding connections, and service entrance work. It shows up on commercial, industrial and residential installations wherever a 1 inch raceway connection has to stay electrically continuous.
