3M 7000149329 Aluminum Connector 250 Kcmil 35 Kv Red

Product Description

The 3M 7000149329 is a 250 kcmil aluminum connector rated for use up to 35 kV in medium-voltage splicing and termination applications. Sold individually, this connector measures 2.94 inches in length with a 0.594-inch inner diameter and a 0.906-inch outer diameter. The connector barrel includes a factory-applied contact aid compatible with polyethylene and EPR insulations, ensuring reliable conductivity at the interface. Licensed electricians and utility splicing crews install this connector when joining or terminating copper or aluminum conductors in medium-voltage cable assemblies.

This connector is suited for residential service entrance, commercial distribution, and utility-grade medium-voltage cable work where aluminum or copper conductors up to 250 kcmil are used. The red color-coded end cap provides quick visual identification of conductor size during installation, reducing the risk of mismatched connector selection on the job. It is appropriate for indoor and outdoor cable splicing systems rated up to 35 kV.

• Compact profile: 2.94 inches long, 0.906-inch OD, 0.594-inch ID

Compatibility

Designed for use with copper or aluminum conductors at 250 kcmil in cable systems rated up to 35 kV. Compatible with polyethylene and EPR insulation types. This part corresponds to 3M Scotchlok Aluminum Connector model 20009 and is also referenced under catalog number 54007-13319.

Installation Notes

Installation of medium-voltage connectors must be performed by a qualified electrician following applicable NEC and local utility codes. De-energize, lock out, and verify the absence of voltage on all conductors before beginning any splice or termination work. Follow the connector manufacturer's installation instructions for proper conductor preparation, insertion depth, and die selection when using a compression tool. Do not mix connector sizes or use damaged connectors.
