Splice Kit for 250 kcmil Conductors

This IDEAL 46-403 kit provides heat-shrink splices rated for cables up to 250 kcmil. It suits electricians joining motor leads, pool wiring or power cables in residential and light-commercial work. The cross-linked polyolefin tubing carries an adhesive liner that seals against moisture when heated.

Replaces Taped or Mechanical Splices

The kit upgrades from vinyl tape or bare mechanical connectors by adding a waterproof, insulated seal that meets the 221 °F maximum operating temperature. The jump is worth it when the installation must survive direct burial, wet locations or vibration that would degrade a taped joint over time.

Limited to 0.7 in Maximum Cable OD

The supplied tubing only fits conductors with an outside diameter up to .7 in, so larger feeders or multi-conductor bundles cannot use this kit. It also requires a heat source capable of fully shrinking the polyolefin; open-flame torches risk uneven recovery and are not recommended by the manufacturer.

Questions about this item

What maximum cable outer diameter will the 0.7 in heat-shrink tubing cover?

The kit’s cross-linked polyolefin tubing is rated for cables up to 0.7 in outside diameter.

Which step is most often missed when shrinking the adhesive-lined tubing onto the splice?

Apply heat evenly until the adhesive liner melts and flows, sealing the connection completely.

How often should the 221 °F-rated splice be inspected after installation?

Inspect the splice periodically for signs of overheating or insulation damage, especially in high-load motor or pool circuits.
