3M 7000149349 Aluminum Connector 35 Kv 3/0 Awg

Product Description

The 3M 7000149349 is an aluminum connector rated for use up to 35 kV, designed for splicing copper or aluminum conductors in medium-voltage electrical applications. This connector fits 3/0 AWG conductors and measures 2.620 inches in length with a 0.484-inch inner diameter and a 0.760-inch outer diameter. A contact aid is pre-loaded in the connector barrel and is compatible with poly and EPR insulations, reducing preparation steps on the job. The ruby color-coded end cap allows for fast visual identification during installation and inspection.

This aluminum connector is suited for medium-voltage cable splicing in residential, commercial, and industrial electrical systems. It is intended for use where copper or aluminum conductors must be reliably joined at voltages up to 35 kV. The pre-applied contact aid in the barrel is formulated for compatibility with poly and EPR insulation systems, making it appropriate for a range of underground and above-grade cable splice applications handled by licensed electricians and utility technicians.

Installation Notes

Installation should be performed by a licensed electrician qualified for medium-voltage work. De-energize and verify the absence of voltage on all conductors before beginning the splice. Follow applicable NEC requirements and local codes for medium-voltage connector installations. Do not exceed the connector voltage rating or use with conductor sizes outside the specified AWG range.
