SAI Advantage
SAI is an industry leader in the switchgear design, build, and retrofit sector because of one simple advantage: our ability to control every aspect of our in-house manufacturing process. Other companies in this industry can only provide “configurable switchgear,” having only standard designs with limited flexibility. SAI boasts custom designs, sizes, and colors with additional options for breaker type, specialized controls and fast track lead-times.
Thanks to a 100% vertically integrated platform, SAI is able to be accountable to be On Time, On Budget and On Spec for all projects. SAI specializes in custom solutions; beginning with raw materials and ending with quality finished products. We are One Team, One Mission, Customer Success with our 100% vertically integrated platform along with our experienced in-house electrical, mechanical & controls engineers.

Our History
We trace our roots back to 1907 in Chicago, where the Switchboard Apparatus Co. was manufacturing electrical apparatus for this growing Midwestern city on the shores of Lake Michigan.
Until 1992, it was owned and operated by three generations of the founding Berthold family. The ownership was then changed to Switchboard Apparatus Inc - built upon the rich tradition of the company’s past.
In 2006, Switchboard Apparatus Inc invested in expanded production capability by building a 50,000 sq. ft. state-of-the-art electrical equipment manufacturing facility in Elmhurst, IL.
The company acquired certain business interests and resources of the Emerson Network Power ASCO Custom Engineered Services unit to create an integrated custom engineering and manufacturing solutions group in 2010.
By combining Switchboard Apparatus and ASCO Engineering Services, it created a strong foundation for a new organization called SAI Advanced Power Solutions.
By 2019, SAI Advanced Power Solutions opened up a new world-class operations center, housed in an 100,000 sq. ft. state-of-the-art facility in Franklin Park, IL.
