IEM is the largest independent full-line manufacturer of electrical distribution and power quality equipment in the U.S.  The Company has developed one of the most sophisticated electrical product manufacturing systems in the world and has cultivated partnerships with leading component suppliers resulting in optimal solutions to customer problems.

Tradition. Technology. Innovation.

For over half a century, IEM has delivered innovative electrical distribution products to meet the escalating needs of growth industries.  Based in the heart of Silicon Valley, IEM has been solving power distribution challenges for Hewlett-Packard, Apple, and dozens of high tech pioneers since they were start-ups.  These companies realized that IEM products were equal to any the multi-nationals could offer and that a faster, more flexible manufacturing system could provide them with the electrical equipment they needed in time to meet their demanding expansion requirements.
Beginning in a barn on a family ranch in Fremont, CA, IEM grew right along with Silicon Valley, moving to a 12,000 square foot facility in 1957, expanding to 70,000 square feet in 1980 then moving to a new state-of-the-art 105,000 square foot facility in 2003.
