The 3M 7000132288 is a multi-mold resin splice kit designed to electrically insulate odd-sized and odd-shaped splices on low-voltage power cables rated through 1 kilovolt (1kV). The kit accommodates stranded conductors ranging from 14 AWG to 2/0 AWG, making it well suited for irregular splice geometries that standard pre-molded sleeves cannot cover. Electricians and cable splicers use this kit when a conventional inline splice sleeve is not a viable option. The resin-based system conforms to the splice profile during cure, creating a durable, moisture-resistant insulating envelope around the connection.
This splice kit is used in low-voltage cable applications up to 1kV where field conditions produce non-standard splice configurations. Typical installation scenarios include junction repairs, tap splices, and multi-conductor joins in conduit, direct-burial, or enclosure environments. The broad AWG range — 14 AWG through 2/0 AWG stranded — covers a wide variety of residential and light commercial wiring repairs and infrastructure cable work. It is sold as a kit containing all components needed to complete the splice encapsulation.
Designed for use on stranded low-voltage power cables rated through 1kV, covering conductor sizes from 14 AWG to 2/0 AWG where non-standard splice shapes require a conforming resin encapsulation method.
Installation is performed by a qualified electrician in accordance with applicable NEC requirements for splice insulation and enclosure. De-energize and lock out the circuit before making or encapsulating any splice. Follow the resin mixing and cure time instructions included with the kit — incomplete cure will compromise insulation integrity. Do not apply the kit to cables exceeding the 1kV voltage rating.
