EZM31600GCBU system correction: Catalog EZM31600GCBU denotes Square D's 1600-amp main circuit-breaker section for a three-phase, four-wire EZ Meter-Pak lineup. Schneider specifies 240VAC maximum and underground service—not 480Y/277 volts.

EZM31600GCBU specifications

  • Catalog number: EZM31600GCBU

Rating coordination needs review

The main-breaker ampere rating and listed horizontal-bus value are separate catalog attributes. The engineered lineup, service calculation, and Schneider application rules must determine whether the configuration is valid.

Before project release

Verify utility acceptance, one-line design, service conductors, grounding, fault current, adjoining bus sections, and underground entry. This equipment should be specified and installed only by the serving utility and qualified electrical professionals.
