3M 7000132746 Underground Feeder Splice Kit 600V

Product Description

The 3M 7000132746 is a splice kit designed to create a reliable, moisture-proof electrical connection in underground feeder cable installations. Rated for 600 volts, this kit is built for type UF-B underground feeder cable and is suitable for copper wire only. The kit includes a 1.8-inch connector and an 8.0-inch heat shrink tube that work together to seal and protect the splice from moisture intrusion. Licensed electricians and electrical contractors install this kit in residential and light commercial applications where underground wiring must be joined and protected against environmental exposure.

This splice kit is used in underground feeder cable runs where a weatherproof, code-compliant connection is required. It accommodates cable sizes ranging from 14/3 without ground wire up to 8/3 with ground wire, covering a broad range of common residential circuit sizes. Typical installation scenarios include outdoor lighting circuits, subpanel feeds, and other below-grade wiring applications where UF-B cable is the specified conductor type.

Key Features

• Moisture-proof splice protection rated for 600-volt UF-B underground feeder cable
• Copper wire only — compatible with 14/3 without ground up to 8/3 with ground
• 1.8-inch connector provides secure mechanical and electrical termination
• 8.0-inch heat shrink tube seals the splice against moisture and soil contact
• Sold as a complete kit with all components required for a single splice

Compatibility

Designed for use with type UF-B underground feeder cable rated for 600 volts, copper wire only, in sizes from 14/3 without ground wire up to 8/3 with ground wire.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements for underground wiring and splice protection. De-energize the circuit and verify it is locked out before making any connections. The heat shrink tube must be fully seated and shrunk evenly around the splice to achieve the moisture-proof seal. Do not use with aluminum conductors or with cable types other than UF-B.
