Square D A9XPCM04 Circuit Breaker Connector 100A

Product Description

The SQUARE D A9XPCM04 is a circuit breaker connector designed to terminate 2 AWG conductors at 100-amp-rated breakers. It serves as an accessory fitting that secures the conductor connection point between the breaker terminal and the distribution assembly. Rated for 100 amps and sized for 2 AWG wire, this connector provides a code-appropriate termination method in panel and load-center wiring applications. Licensed electricians and panel installers use this connector when building out or servicing busbar-based distribution equipment. The compact form factor — measuring 4 inches wide, 3.6 inches in length, and 1 inch in height — keeps installation tidy inside enclosures where space is limited.

This connector is intended for use with comb busbar systems, which are common in residential and light commercial electrical distribution panels. It is well-suited to applications where multiple circuit breakers share a common busbar assembly and a reliable, low-resistance conductor termination is required. Electricians working on load centers, sub-panels, and multi-breaker distribution boards will encounter this style of connector in standard panel assembly and retrofit scenarios.

Compatibility

Designed for use with SQUARE D comb busbar systems. Specific compatible breaker or panel model numbers were not provided in available product data; verify fitment against the busbar assembly in use before installation.

Installation Notes

Installation should be performed by a qualified electrician in accordance with applicable NEC requirements. De-energize the panel and verify the absence of voltage at all terminals before handling any busbar or breaker connections. Use the correct torque specification listed on the breaker or busbar terminal label, as over- or under-torquing conductor terminations can cause connection failures or heat damage. Confirm conductor gauge and connector rating match the overcurrent protection device before final assembly.
