  • TypeElectrical Connectors
  • Handles up to 1,000 V for reliable high-voltage splices
  • EPDM rubber insulation resists heat up to 194 °F
  • Kit includes mastic strips, lug covers and grease for complete sealing
  • CSA approved and RoHS compliant for code-compliant installations

3M 5300 Wire Connector Kit for Motor Leads

The 3M 5300 kit provides heat-shrink splice components for pigtail and one-hole lug connections on motor lead cable. It includes three mastic sealing strips, three pigtail lug covers, three tubes of silicone grease and an instruction sheet. The EPDM rubber insulation is rated for 1000 V and a maximum operating temperature of 194 degrees F.

Suited for 12 AWG to 16 AWG copper wire splicing

This kit covers wire sizes from 12 AWG down to 16 AWG and carries CSA approval and RoHS compliance. It is not intended for conductors larger than 12 AWG or smaller than 16 AWG, nor for applications exceeding the 1000 V rating. Buyers needing higher voltage ratings or different wire ranges should look at alternative products.

Verify wire gauge and voltage before ordering

Confirm that the motor lead cable falls within the 12 AWG to 16 AWG range and that the circuit voltage does not exceed 1000 V. Ensure the installation environment stays within the 194 degrees F temperature limit. The kit is restricted from sale in California under Proposition 65 due to a listed chemical.

Questions about this item

What wire gauges must I already have on hand for the 3M 5300 kit to accept them?

The connectors accept 12 AWG down to 16 AWG motor-lead cable, so you need wire within that range.

Will the EPDM rubber insulation and 1000 V rating stay reliable if I leave older 16 AWG pigtail splices in the same harness?

Yes, the kit is rated for 1000 V and 194 °F maximum operating temperature across the full 12–16 AWG range, so existing 16 AWG pigtails remain within spec.

After shrinking the tubes and applying the mastic strips, what visual cue confirms each lug cover is sealed to spec?

The mastic strips should fully extrude around the lug cover edges and the EPDM tubing should show uniform recovery with no gaps or wrinkles.
