GB Gardner Bender 25-AWC WireGard™ Color Coded Screw-On Wire Connectors User Manual

Introduction

This manual provides essential instructions for the safe and effective use of GB Gardner Bender 25-AWC WireGard™ Color Coded Screw-On Wire Connectors. These connectors are designed for secure electrical connections in various applications. Please read this manual thoroughly before installation and retain it for future reference.

Important Safety Instructions

• Always disconnect power at the circuit breaker or fuse box before working with electrical wiring. Failure to do so can result in serious injury or death.
• Ensure all electrical work complies with local electrical codes and regulations. If you are unsure, consult a qualified electrician.
• Use these connectors only for copper-to-copper connections. Do not use with aluminum wiring.
• Verify that the wire gauge and number of wires are within the specified range for the connector being used.
• Inspect connectors for any damage before use. Do not use damaged connectors.
• Wear appropriate personal protective equipment, such as safety glasses and insulated gloves, when performing electrical work.

Setup: Installation Preparation

Before beginning any electrical work, ensure you have the necessary tools and have taken all safety precautions.

Tools Required:

• Wire strippers
• Lineman's pliers (optional, for twisting wires)
• Voltage tester
• Safety glasses and insulated gloves

Wire Preparation:

1. Turn off power: Locate the circuit breaker or fuse controlling the circuit you will be working on and turn it off. Verify power is off using a voltage tester.
2. Strip wires: Using wire strippers, carefully strip approximately 1/2 to 5/8 inch of insulation from the ends of the wires to be connected. Ensure the copper conductor is clean and free of nicks.
3. Check wire gauge: Confirm that the wires you are connecting are within the appropriate gauge range for the selected WireGard™ connector. Refer to the connector's packaging or specifications for details.

Operating: Connection Procedure

Follow these steps to make a secure and safe electrical connection using WireGard™ connectors:

1. Align wires: Hold the stripped ends of the wires to be connected together, ensuring they are parallel and the bare copper ends are even.
2. Twist wires (optional but recommended): For a more robust connection, gently twist the bare wire ends together clockwise with pliers before applying the connector.
3. Apply connector: Place the appropriate size WireGard™ connector over the twisted (or aligned) bare wire ends.
4. Screw on: Twist the connector clockwise onto the wires. Continue twisting until the connector is tight and the wires are securely held. The insulation of the wires should be fully enclosed within the connector's skirt, with no bare copper visible.
5. Test connection: Gently tug on each wire individually to ensure it is firmly seated within the connector and cannot be pulled out.
6. Insulate (if necessary): If the connection is in an area exposed to moisture or physical stress, consider wrapping the connector with electrical tape for added protection, though the high-dielectric shell provides significant insulation.

Important: These connectors are designed for copper-to-copper connections only. Using them with aluminum wires can lead to unsafe connections and potential hazards.

Maintenance

WireGard™ connectors are designed for long-term, maintenance-free operation once properly installed. Regular maintenance is generally not required for the connectors themselves.

• Periodic Inspection: For critical applications, periodically inspect electrical connections for any signs of loosening, corrosion, or overheating (discoloration of the connector or wire insulation).
• Storage: Store unused connectors in a dry, cool place away from direct sunlight and chemicals to preserve their material integrity.

Troubleshooting

If you encounter issues with your electrical connections, consider the following:

• Loose Connection: If a wire pulls out or feels loose, disconnect power, remove the connector, re-strip the wire ends if necessary, and re-apply the connector, ensuring it is twisted on firmly until tight.
• No Power: If a circuit is not receiving power after installation, first verify that the circuit breaker is on. Then, check all connections for proper seating and ensure no bare wires are exposed. Re-check wire stripping and connector application.
• Overheating: If a connector or surrounding wires show signs of overheating (e.g., melting, discoloration, burning smell), immediately disconnect power. This indicates an improper connection, overloaded circuit, or incorrect wire gauge. Do not re-energize until the cause is identified and corrected by a qualified professional.
