3M 5302 Wire Connector Kit

The 3M 5302 kit provides insulated splices for 1/0 AWG motor lead cables up to 1,000 V. It uses EPDM rubber heat-shrink bodies and copper lugs to seal pigtail and one-hole lug connections in industrial and automotive electrical work. Electricians and maintenance technicians who need a CSA-approved, RoHS-compliant splice for large-gauge cable will find the required components in this package.

Before ordering wire connector kit

Verify that your cable falls within the 4 AWG to 1/0 AWG range and that the system voltage does not exceed 1,000 V. Confirm the lug style matches a pigtail or one-hole configuration and that the operating temperature stays at or below 194 °F. The kit includes locking pins, mastic strips, lug covers, silicone grease and an instruction sheet, so no additional sealing hardware is required for the listed applications.

Thermals noise and power draw

The EPDM rubber insulation is rated for continuous operation up to 194 °F, maintaining seal integrity under normal load temperatures. As a passive splice kit it generates no audible noise and draws no power of its own. The copper contacts and mastic seals preserve conductivity without adding thermal resistance to the circuit.

Questions about this item

What comes in the 3M 5302 kit and what must I supply?

The kit includes an instruction sheet, three locking pins, three mastic sealing strips, three pigtail lug covers and three tubes of silicone grease; you must supply the motor-lead cable and lugs sized for 4 AWG to 1/0 AWG.

How do I choose the right version of the 5302 kit for my cable size?

This single kit covers the full range from 4 AWG minimum up to 1/0 AWG maximum, so select it whenever your motor leads fall inside that window.

What does the 1000 V rating mean when the splice is installed in a motor circuit?

It certifies the EPDM rubber insulation for continuous operation at up to 1000 volts and 194 degrees Fahrenheit in pigtail or 1-hole lug connections.
