3M 5301 Wire Connector Kit 4 AWG

The 3M 5301 kit provides EPDM rubber insulated connectors for splicing motor lead cables up to 4 AWG maximum wire size. It is designed for pigtail and one-hole lug connections rated at 1,000 V. The kit suits electricians and maintenance technicians needing reliable, heat-shrinkable splices in industrial or automotive electrical work.

Check wire gauge and voltage before ordering

Verify that your conductors fall between the 12 AWG minimum and 4 AWG maximum wire sizes specified for this kit. Ensure the circuit voltage does not exceed the 1,000 V rating and that the operating environment stays within the 194 degrees F maximum temperature limit. Confirm compatibility with copper contact material and pigtail or lug connection types.

Included accessories complete the splice

The package supplies three mastic sealing strips, three pigtail lug covers and three tubes of silicone grease to seal and protect each connection. An instruction sheet guides the installation process for proper heat-shrink application. These components work together to deliver a CSA approved, RoHS compliant splice meeting the stated voltage and temperature ratings.

Questions about this item

What comes in the 3M 5301 kit and what must I supply myself?

The kit includes one instruction sheet, three mastic sealing strips, three pigtail lug covers and three tubes of silicone grease. You must provide the motor lead cable and any crimp lugs sized between 12 AWG and 4 AWG.

Should I choose this kit for a 12 AWG wire or a 4 AWG wire?

The kit covers the full range from 12 AWG minimum to 4 AWG maximum, so it works for either size as long as the conductor falls within that span.

What does the 1,000 V rating mean when the splice is installed in a motor circuit?

It certifies the EPDM rubber insulation and mastic seals for continuous operation up to 1,000 V and 194 °F, matching CSA approval for pigtail and 1-hole lug connections.
