Square D CU250JD Circuit Breaker Mechanical Lug 1/0 Awg

Product Description

The SQUARE D CU250JD is a mechanical lug accessory designed for use with compatible Square D circuit breakers. Mechanical lugs provide a direct wire termination point, allowing conductors to be landed without a separate lug kit. This accessory accommodates 1/0 AWG conductors and is intended for use in residential and commercial electrical distribution panels. Licensed electricians install this component during panel assembly, service upgrades, or breaker replacement work where a mechanical lug termination is required in place of a bus lug configuration.

This mechanical lug accessory is suited for use in branch circuit and feeder applications where 1/0 AWG conductor terminations are needed at the circuit breaker. It is commonly installed in load centers and distribution panels during new construction or retrofit projects. Its compact form factor fits within standard panel enclosures without requiring additional clearance modification. Electricians select this lug type when a direct, secure conductor connection to the breaker is required by the installation design or local code.

Key Features

• Mechanical lug design provides direct conductor termination at the circuit breaker
• Rated for 1/0 AWG conductors, suitable for feeder and branch circuit applications
• Compact dimensions of 1 inch height, 2 inches width, and 3.2 inches length for panel-friendly fit
• OEM-style accessory designed to install cleanly with compatible Square D breakers
• Lightweight at 0.65 pounds, minimizing added load to the panel assembly

Compatibility

Designed as an OEM-style replacement mechanical lug accessory for compatible Square D circuit breakers. Verify breaker model compatibility before installation, as lug accessories are breaker-specific.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the panel and verify the absence of voltage with a properly rated meter before handling any breaker components. Torque conductor terminations to the value specified on the breaker or lug label. Do not use this accessory on breakers outside the listed compatible product family.
