Key Features:
- Application: Designed for flexible metallic liquidtight conduit and Type B flexible nonmetallic liquidtight conduit.
- Corrosion Protection: All metallic components are zinc-electroplated.
- Seal Integrity: Features an innovative split gland-ring to ensure a perfect seal and prevent pullouts.
- Secure Connection: Includes a sealing washer and heavy-duty locknut for positive bonding to a box or enclosure.
- Reusability: All components are designed to be reusable.
- Noninsulated: This model is noninsulated.
2. Safety Information
WARNING: Electrical installations should only be performed by licensed electricians in compliance with all national and local electrical codes. Failure to follow these instructions and codes can result in electrical shock, fire, serious injury, or death.
- Always disconnect power at the circuit breaker or fuse box before installing or servicing electrical components.
- Ensure all connections are secure and properly torqued to prevent loose connections and potential hazards.
- Verify that the connector size matches the conduit and knockout size for a proper fit and seal.
- Inspect the connector and conduit for any damage before installation. Do not use damaged components.
3. Installation Instructions
Follow these steps for proper installation of the Hubbell-Raco 3441 Liquidtight Connector:
- Prepare Conduit: Cut the flexible liquidtight conduit to the desired length. Ensure the cut is clean and free of burrs.
- Disassemble Connector: Unscrew the gland nut from the connector body. The split gland-ring and sealing washer should be removed from the connector body if not already separate.
- Insert Conduit: Slide the gland nut, then the split gland-ring, and finally the sealing washer over the end of the conduit in that order.
- Secure Conduit to Connector Body: Insert the conduit end into the connector body. Ensure the conduit is fully seated against the internal stop. Slide the sealing washer and split gland-ring into position against the connector body.
- Tighten Gland Nut: Hand-tighten the gland nut onto the connector body, then use a wrench to tighten it securely. This compresses the split gland-ring and sealing washer, creating a liquidtight seal around the conduit. Do not overtighten.
- Insert Connector into Enclosure: Insert the threaded end of the connector into the appropriate knockout hole of the electrical box or enclosure.
- Secure with Locknut: Place the heavy-duty locknut over the threaded end of the connector inside the enclosure. Hand-tighten the locknut, then use a wrench to tighten it firmly against the enclosure wall. Ensure the locknut teeth bite into the enclosure surface for proper bonding and ground continuity.
- Verify Connection: Double-check all connections for tightness and ensure the liquidtight seal is properly formed.
4. Operation
Once properly installed, the Hubbell-Raco 3441 Liquidtight Connector functions passively by maintaining a secure, liquidtight connection between the conduit and the electrical enclosure. Its primary role is to protect wiring from moisture, dust, and other environmental contaminants, while also ensuring electrical continuity and bonding.
5. Maintenance
The Hubbell-Raco 3441 Liquidtight Connector requires minimal maintenance. Regular inspection is recommended to ensure continued performance and safety:
- Periodic Visual Inspection: Annually, or more frequently in harsh environments, visually inspect the connector for any signs of physical damage, corrosion, or wear.
- Check for Tightness: Ensure the gland nut and locknut remain securely tightened. Loose connections can compromise the liquidtight seal and electrical bonding.
- Cleanliness: Keep the connector free from excessive dirt, debris, or chemical buildup that could degrade its material over time.
- Environmental Factors: If the connector is exposed to extreme temperatures, vibrations, or corrosive substances, increase the frequency of inspections.
6. Troubleshooting
Should issues arise with your Hubbell-Raco 3441 Liquidtight Connector, consider the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Water or moisture ingress | Gland nut not tightened sufficiently; damaged sealing washer or gland-ring; incorrect conduit size. | Ensure gland nut is securely tightened. Inspect and replace sealing washer or gland-ring if damaged. Verify conduit matches connector size. |
| Conduit pullout | Gland nut not tightened sufficiently; split gland-ring not properly seated. | Re-tighten gland nut securely. Ensure split gland-ring is correctly positioned and engaged with the conduit. |
| Poor electrical bonding/grounding | Locknut not tightened securely; locknut teeth not biting into enclosure; corrosion on contact surfaces. | Ensure locknut is firmly tightened with its teeth making good contact. Clean any corrosion from contact surfaces. |
| Connector corrosion | Exposure to harsh chemicals or extreme environments beyond product rating. | Regularly inspect and clean. If severe, replacement may be necessary. Consider alternative materials if environment is highly corrosive. |
