Company Profile

We have been building switchboards and switchgear products since 1972. Originally located in Anaheim - California, we relocated our facilities during February 1985 to Brea,California, where we continued to prosper and grow for over 15 years. In June 2000 we moved to a larger plant in the City of Anaheim. Our plant now consists of two buildings (over 45,000 sq. ft.) and the company has over 100 employees. The company has undertaken an ongoing plant upgrade that places us as one of the most modern Switchgear plants on the West Coast.


It is our firm belief that an important part of the RSE-Sierra success story has been that for a relatively small company to compete in a market dominated by the giants of the industry, we must endeavor to provide a higher level of quality in service and product than that available from the majors.
