Introduction
This manual provides essential information for the safe and effective installation, operation, and maintenance of the Ocal HUB1-G 1-Inch PVC Coated Hub. The HUB1-G is designed for electrical conduit applications requiring corrosion resistance and a secure connection to enclosures.
Safety Information
Always adhere to the following safety guidelines to prevent injury or damage to equipment:
- Disconnect Power: Ensure all power to the electrical system is disconnected before beginning any installation or maintenance procedures.
- Qualified Personnel: Installation and maintenance should only be performed by qualified electricians in accordance with all national and local electrical codes.
- Personal Protective Equipment (PPE): Wear appropriate PPE, including safety glasses and gloves, during installation.
- Inspect Components: Before installation, inspect all components for any signs of damage. Do not install damaged parts.
Product Overview
The Ocal HUB1-G is a corrosion-resistant knockout hub featuring robust construction and a protective PVC coating. It is engineered to provide a reliable and sealed connection for 1-inch conduits.
Key Features:
- Corrosion Resistance: Constructed from zinc or copper-free aluminum with a nominal 0.04-inch (40 mil) PVC coating bonded to the exterior.
- Secure Connection: Features a hexagonal/splined body and locknut for fast and easy installation.
- Sealing Integrity: A captive sealing ring provides a complete 360-degree seal, even when the conduit is not perfectly perpendicular to the enclosure.
- Thermoplastic Insulation: Includes a 1-inch thermoplastic insulated throat.

Setup and Installation
Follow these steps for proper installation of the Ocal HUB1-G hub:
- Prepare Enclosure: Ensure the enclosure has a properly sized knockout or threaded opening for a 1-inch conduit.
- Thread Hub: Thread the Ocal HUB1-G hub into the prepared opening of the enclosure.
- Secure Locknut: Hand-tighten the hexagonal/splined locknut onto the hub from the inside of the enclosure.
- Final Tightening: Use an appropriate wrench to firmly tighten the locknut, ensuring a secure connection. The captive sealing ring should compress to create a complete 360-degree seal against the enclosure surface.
- Connect Conduit: Thread the 1-inch conduit into the hub. Ensure the conduit is fully engaged and tightened to prevent movement and maintain the seal.

Operating
Once correctly installed, the Ocal HUB1-G functions as a permanent, sealed, and corrosion-resistant connection point for electrical conduits to an enclosure. It requires no active operation.
Maintenance
The Ocal HUB1-G is designed for minimal maintenance. However, periodic inspection is recommended:
- Visual Inspection: Annually inspect the hub and its connection points for any signs of physical damage, cracking of the PVC coating, or corrosion.
- Seal Integrity: Verify that the sealing ring remains intact and that the connection to the enclosure is still tight and secure.
- Cleaning: If necessary, clean the exterior of the hub with a damp cloth. Avoid abrasive cleaners that could damage the PVC coating.

Troubleshooting
Should issues arise, consider the following:
- Loose Connection: If the conduit or hub feels loose, re-tighten the locknut and the conduit connection. Ensure the sealing ring is properly compressed.
- Signs of Corrosion: If significant corrosion is observed on the metal components despite the PVC coating, the hub may need to be replaced. Ensure the PVC coating is not compromised.
- Water Ingress: If water or moisture is found inside the enclosure at the hub connection, check the tightness of the hub and the integrity of the sealing ring. Re-installation or replacement may be necessary.
