1. Product Overview
The Morris 94164 Copper SB 2-Hole Compression Lug is a high-quality electrical connector designed for secure and reliable termination of copper conductors. This lug features a seamless barrel for optimal crimping and two bolt holes for robust mechanical and electrical connection to bus bars, panels, or other electrical components. It is suitable for heavy-duty applications requiring durable and efficient power transmission.

2. Safety Information
Always adhere to local electrical codes and safety regulations when working with electrical components. Failure to do so may result in serious injury or property damage.
- Ensure all power sources are disconnected and locked out before beginning any installation or maintenance work.
- Use appropriate personal protective equipment (PPE), including insulated gloves, safety glasses, and non-conductive footwear.
- Only qualified personnel should perform electrical installations.
- Verify the lug's compatibility with the conductor size and material before installation.
3. Installation (Setup)
Proper installation is crucial for the long-term performance and safety of the electrical connection. Use a high-quality crimping tool specifically designed for copper compression lugs.
Required Tools:
- Hydraulic or Mechanical Crimping Tool with appropriate dies for 3/0 AWG copper.
- Wire Strippers/Cutters.
- Wire Brush or Abrasive Pad.
- Torque Wrench (for bolt connections).
Installation Steps:
- Prepare the Conductor: Strip the insulation from the copper conductor to the length specified by the lug's barrel depth. Ensure the stripped end is clean and free of nicks or burrs.
- Clean the Conductor: Use a wire brush or abrasive pad to remove any oxidation from the stripped copper conductor.
- Insert Conductor: Insert the cleaned conductor fully into the lug barrel until it bottoms out.
- Crimp the Lug: Using the correct die size for 3/0 AWG, perform the required number of crimps according to the crimping tool manufacturer's instructions. Ensure each crimp is complete and secure.
- Inspect Crimp: Visually inspect the crimped connection for proper deformation and secure attachment.
- Secure to Surface: Align the two bolt holes of the lug with the corresponding holes on the bus bar or connection point. Insert appropriate bolts and washers.
- Torque Bolts: Tighten the bolts to the manufacturer's recommended torque specifications using a torque wrench to ensure a secure and low-resistance electrical connection.
4. Function and Operation
Once properly installed, the Morris 94164 Compression Lug provides a permanent, low-resistance electrical connection between a 3/0 AWG copper conductor and an electrical component. Its robust design ensures efficient current flow and mechanical stability under various operating conditions. The lug is designed to maintain its integrity and conductivity over its service life, provided it is installed correctly and not subjected to conditions beyond its specified ratings.
5. Maintenance
Regular inspection of electrical connections is recommended to ensure continued safety and performance.
- Visual Inspection: Periodically inspect the lug and connection for signs of corrosion, discoloration (indicating overheating), or physical damage.
- Tightness Check: If accessible and safe to do so (with power disconnected), check the tightness of the bolted connection. Do not overtighten.
- Cleaning: If minor surface oxidation is present, gently clean the lug with a non-abrasive cloth. For severe corrosion, the connection may need to be disassembled (with power off) and re-established.
- Thermal Imaging: For critical applications, consider periodic thermal imaging to detect hot spots that may indicate a high-resistance connection.
6. Troubleshooting
Common issues related to compression lugs are typically due to improper installation or environmental factors.
| Problem | Possible Cause | Solution |
|---|---|---|
| Overheating at connection point | Loose bolt connection, improper crimp, undersized lug for current. | Ensure bolts are torqued correctly. Re-crimp or replace lug if crimp is faulty. Verify lug sizing. |
| Corrosion on lug surface | Exposure to moisture or corrosive agents. | Clean the surface. Consider environmental protection (e.g., heat shrink tubing) for future. |
| Conductor pulls out of lug | Insufficient crimps, incorrect die size, improper crimping tool. | Replace lug and re-crimp using correct tools and procedures. |
