An MCC (Motor Control Center) and switchgear are related but distinct types of electrical assemblies. MCCs are specifically designed to control and distribute power to multiple motors from a centralized enclosure, while switchgear — such as DEI Power's UL 891-certified switchboards, service entrance switchgear, meter mains, and service entrance sections (SES) — is designed for broader power distribution, protection, and isolation across commercial, industrial, utility, and data center applications. Both serve large-scale power distribution needs, but switchgear typically handles the higher-level distribution from 400A to 4000A before power reaches motor control equipment.
