Ilsco AS250 Aluminum Compression Sleeve 250 Mcm

Product Description

The ILSCO AS250 is an aluminum compression sleeve designed for butt-splice connections on large-gauge conductors. It accepts 250 MCM wire with a conductor diameter of 0.575 inches and is dual rated for use with both aluminum and copper conductors. This type of compression sleeve is a standard component in heavy electrical distribution work, used to create a permanent, low-resistance splice in the field. Installation requires a compatible hydraulic or mechanical compression tool sized for the connector. Licensed electricians performing wire splicing on feeders and service entrances are the primary users of this part.

The AS250 is suited for residential and commercial electrical applications where 250 MCM conductors are spliced in panel feeders, service entrance runs, or distribution wiring. Its dual-rated construction means the same sleeve can be used whether the job calls for aluminum or copper conductors, reducing the need to stock separate parts for each material type. It is also referenced in the field as AS-250 and by the UPC 783669000504.

Key Features

• Dual rated for aluminum and copper conductors - one part covers both material types
• Accepts 250 MCM wire with a conductor diameter of 0.575 inches
• Compression-style installation creates a permanent, gas-tight butt splice
• Aluminum construction keeps weight low on large-gauge installations
• Also referenced as AS-250 and UPC 783669000504 for cross-referencing and procurement

Compatibility

Designed as an OEM-style compression butt splice for 250 MCM aluminum or copper conductors in heavy electrical distribution and service entrance applications.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements for conductor splicing and termination. De-energize and lock out the circuit before beginning any splice work. Use a hydraulic or ratchet compression tool rated for the connector size and die set; do not use open-barrel crimping tools not specified for compression sleeves. Inspect the completed crimp for full die closure and verify conductor seating before insulating the splice.
