Square D 9999LB0 Starter Lug Extender Kit

Product Description

The SQUARE D 9999LB0 is a starter lug extender kit designed to extend the lug connection points on motor starters and overload relays. This accessory provides the additional reach needed when field wiring does not land cleanly on the standard lug position, reducing stress on conductors and termination points. It is a direct-fit starter accessory intended for use by licensed electricians and industrial maintenance technicians working on motor control equipment. The kit ships as a single unit and is compatible with the Motor Logic overload relay product family.

This lug extender kit is used in motor control center (MCC) applications and panel-mounted starter configurations where conductor routing or conduit entry angles create clearance challenges at the lug. It is a common accessory replacement in both new installations and field service work on existing motor starter assemblies. The compact form factor, measuring 3.3 inches in length, 2.8 inches in width, and 2.2 inches in height, allows it to fit within tight enclosure footprints typical of industrial motor control equipment.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the National Electrical Code (NEC). De-energize the motor control circuit and verify zero voltage at the starter before beginning any work on lug connections. Ensure conductor sizing and torque requirements follow the motor starter manufacturer specifications and applicable local codes. Do not apply power until all lug connections are fully seated and the enclosure is secured.
