Switchgear (UL 891) provides enhanced overcurrent protection and is designed for higher fault-current environments. A switchboard distributes power to multiple circuits and is typically used downstream. A Service Entrance Section (SES) is the utility-facing component that must be built to approved utility specifications and is the first point of electrical entry into a facility.

Yes. All products are UL 891 certified and UL listed assemblies, ensuring compliance with applicable electrical codes. They also meet UBC, CBC, and IBC requirements for all seismic zones and are EUSERC approved, making them suitable for utility-grade service entrance installations across the United States.
