Square D AL100FA Circuit Breaker Mechanical Lug Kit

Product Description

The SQUARE D AL100FA is a mechanical lug kit designed as an accessory for compatible Square D circuit breakers. It provides a reliable termination point for field wiring, allowing electricians to land conductors directly to the breaker without requiring a separate lug assembly. The kit accommodates wire sizes from 14 AWG through 1/0 AWG, making it suitable for a range of branch circuit and feeder applications. At 0.1 pounds, it is a compact add-on component that installs directly onto the breaker in the panelboard or loadcenter during rough-in or service work.

This lug kit is used in residential and light commercial electrical installations where a circuit breaker requires a mechanical lug termination rather than a standard pressure-plate wire connection. It is typically installed inside a loadcenter or distribution panel by a licensed electrician during new construction, panel upgrades, or service modifications. The 14-1/0 AWG wire range covers most single-phase branch and feeder conductor sizes used in these applications.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the panel before installing or servicing any breaker accessory. Torque all lug fasteners to the value specified on the breaker or lug kit labeling. Verify conductor insulation is stripped to the correct length per the lug manufacturer instructions before landing the wire.
