Burndy QR40-600-800-MCM-3-5-8 Reducing Cable Splice

Burndy QR40 is a QIKLINK copper reducing splice designed for copper‑to‑copper cable connections, reducing from 800 kcmil to 600 kcmil. This 3-5/8‑inch long connector carries two screws for securing conductors and is offered in unplated copper for durability in distribution systems. The QR40 family is rated for high‑current applications, with a recommended tightening torque of 500 in‑lb to ensure a solid, code‑compliant connection. The part accepts copper conductors on the respective ends within the 600 to 800 kcmil range, enabling a direct splice or reducer without additional hardware. Typical uses include service entrances, feeders, and switchgear terminations where a larger conductor must join or transition to a smaller size within the 600–800 kcmil range. The Burndy QR40 designation identifies a precision‑machined QIKLINK connector known for mechanical strength and reliable electrical performance in demanding installation environments.
