LV Switchgear

Easter-Owens is a full-service fabrication and integration facility with the ability to design and construct custom UL 891 switchboards – whether for single-application products or developing standard OEM configurations for rapid deployment. Our LV switchgear units are built utilizing power and control components from a variety of industry-leading manufacturers.

Easter-Owens switchboards are all designed by our professional engineers. We then bend, punch, pierce and form both copper and steel in-house. The switchboards progress through fabrication and powder coating before being wired and tested. The entire process takes place at our facility in Arvada, Colorado.
