Topaz Lighting 32 Bronze Grounding Hub

Topaz Lighting's Bronze Grounding Hub connects rigid conduit to water pipes using ground pipe clamps, delivering reliable ground path continuity for code-compliant electrical grounding systems. Precision-manufactured entirely from bronze for outstanding corrosion resistance, this UL Listed hub is available in 1/2", 3/4", and 1" trade sizes to fit a wide range of rigid conduit installations, from small branch circuits to larger service runs. Electrical contractors and installers specify these grounding hubs whenever a dependable, corrosion-resistant bonding path between rigid conduit and a water pipe grounding electrode is required, and the bronze body stands up to damp basements, mechanical rooms, and other demanding job-site conditions where lesser materials would corrode.

Topaz Lighting 31" – Frequently Asked Questions

1) What does a Topaz bronze grounding hub actually do on a conduit run?
It bonds rigid conduit to a water pipe grounding electrode. The hub threads onto the conduit and the connection to the water pipe is made with a ground pipe clamp, maintaining ground path continuity for the raceway. It is not a fitting for terminating conductors or for joining two lengths of conduit.
2) Will a Topaz bronze grounding hub work on IMC, or only rigid?
Both. The hub is rated for Rigid/IMC conduit, so it threads onto standard rigid metal conduit or intermediate metal conduit of the same trade size. It is not intended for EMT, which is not threaded.
3) Does the grounding hub come with the pipe clamp, or do I order that separately?
The hub is the conduit-side fitting only. The ground pipe clamp that grabs the water pipe is a separate item, sized to the water pipe rather than to the conduit, and so is the bonding conductor between them. Plan on all three pieces to finish the connection.
4) What trade sizes do Topaz bronze grounding hubs come in?
Three: 1/2 inch, 3/4 inch and 1 inch. The catalog numbers run 31 for 1/2 inch, 32 for 3/4 inch and 33 for 1 inch, so the number tracks the size. Order by trade size of the conduit it threads onto.
5) Is a bronze grounding hub worth it over a steel fitting in a damp mechanical room?
That is exactly the case for it. The body is bronze throughout, not plated steel, so a wet basement, mechanical room or other moisture-prone location will not eat the bonding path. Corrosion at a ground connection is what takes continuity out over time, and bronze is the reason this version gets specified for those spots.
