Thomas & Betts OCAL STG1-G PVC-Coated Zinc Ground Hub Fitting

The Thomas & Betts OCAL STG1-G is a PVC-coated zinc ground hub built to provide dependable electrical grounding continuity at the point where conduit terminates into an enclosure. As part of the Thomas & Betts OCAL PVC-coated fitting system, the STG1-G pairs a rugged zinc body with an applied PVC coating for enhanced corrosion resistance, making it well suited for grounding connections in conduit systems that see harsh or corrosive service conditions. The STG1-G designation identifies this specific ground hub within the OCAL catalog, giving installers a clear reference point when specifying PVC-coated grounding fittings for a project. The OCAL line is built around this same coated-fitting approach, and the STG1-G ground hub carries that construction through to the grounding point of the raceway.

Key Features

  • OCAL Series Construction: The STG1-G is manufactured as part of the Thomas & Betts OCAL PVC-coated fitting family, a product line built around corrosion-resistant coated components for demanding electrical environments.
  • Zinc Body: The hub is constructed from zinc, providing the strength needed for a secure, long-lasting conduit-to-enclosure grounding connection.
  • PVC Coating: A PVC coating (CTD) is applied over the zinc base, adding a protective barrier against corrosion beyond what an uncoated fitting can offer.
  • Ground Hub Function: As a ground hub, the STG1-G bonds the conduit run to the enclosure it enters, supporting continuous grounding path integrity through the raceway system.
  • OCAL STG1-G Model: Identified within the Thomas & Betts OCAL grounding hub lineup by the STG1-G model designation for clear specification and ordering.
  • Coated Fitting System Compatibility: Designed to work within the broader OCAL PVC-coated conduit and fitting system for consistent corrosion protection across an installation.

Typical Applications

  • Conduit Grounding and Bonding Connections
  • Corrosive and Wet-Location Conduit Installations
  • Industrial and Outdoor Electrical Systems
  • Enclosure and Panel Grounding Terminations
  • PVC-Coated Conduit System Installations
  • Renovation and New Construction Electrical Projects

Why Thomas & Betts?

Thomas & Betts brings extensive electrical fitting expertise to the OCAL PVC-coated product line, pairing a durable zinc body with a protective PVC coating to help installations hold up in corrosive and demanding environments. The STG1-G ground hub is built to deliver dependable grounding continuity at conduit-to-enclosure connections, supporting reliable, code-conscious performance for professional electrical work. This construction reflects the broader OCAL approach of combining a strong metal body with a protective PVC coating so grounding fittings can stand up to the same conditions as the rest of a coated conduit system. For installers standardizing on a single coated-fitting platform, the STG1-G lets grounding hardware match the corrosion resistance of the surrounding OCAL conduit run, from body to bushing to hub, so the entire raceway assembly presents the same protective barrier against moisture, chemicals, and outdoor exposure. Specifying the STG1-G by its OCAL model designation also simplifies procurement and ensures the correct PVC-coated zinc grounding fitting is installed at each conduit-to-enclosure entry point on the job.

Ocal STG1-G – Frequently Asked Questions

1) What trade sizes does the Ocal STG ground hub come in, and which part number is which?
Three trade sizes: 1/2 inch is STG1-G, 3/4 inch is STG2-G, and 1 inch is STG3-G. Order by the part number matching your conduit trade size, since the hub threads onto the conduit end and bonds it to the box or enclosure.
2) Will the Ocal STG ground hub match the rest of my PVC-coated conduit run?
Yes. The hub is a zinc body with an applied PVC coating, dark gray, built as part of the Ocal PVC-coated fitting system, so the grounding termination carries the same coated barrier as the coated conduit and fittings around it. That is the point of specifying it instead of a bare zinc hub on a coated system.
3) What does a ground hub do that a plain locknut and bushing connection does not?
A ground hub positively bonds the conduit to the box or enclosure, so the raceway and the enclosure stay on one continuous grounding path. The Ocal STG hub does that at the conduit entry point rather than relying on a locknut-to-sheet-metal connection, and it accepts a grounding conductor at the hub lug. Use it where you need a deliberate bonding termination at the panel or enclosure wall.
4) Can I use a PVC-coated ground hub in a wet or corrosive outdoor location?
That is the service this fitting is built for. The PVC coating over the zinc body is there to resist moisture, chemicals, and outdoor exposure at the conduit-to-enclosure entry, which is where an uncoated hub usually corrodes first. Typical use is industrial, outdoor, and wet-location conduit work where the rest of the raceway is already coated.
5) I need to ground a conduit entry larger than 1 inch. Does the Ocal STG hub go bigger?
No. The STG-G ground hub range tops out at 1 inch trade size (STG3-G). For anything above 1 inch you need a different coated hub size from the Ocal line, not this one.
6) Is the Ocal STG1-G the same thing as a regular ground hub with the model number STG1?
The -G suffix is how the coated grounding hub is identified in the Ocal catalog. Specify STG1-G, STG2-G, or STG3-G by that full designation when you want the PVC-coated zinc version, so the correct coated fitting lands at each conduit-to-enclosure entry instead of a bare-metal substitute.
