Rexel SA, the world’s largest electrical distributors, has 1,686 branches in 24 countries.

GE Supply, headquartered in Shelton, Conn., is a leading distributor of electrical products produced by GE and more than 200 other manufacturers. With approximately 2,500 employees in more than 150 locations around the world, GE Supply’s core electrical distribution activities operate mainly in the United States. It ranked No. 4 on Electrical Wholesaling’s most recent Top 200. With $2.2 billion in pro forma 2005 annual revenues for the transferred business to Rexel, the combined distributors could capture the No. 1 spot.
