Major companies include US-based Hubbell, Leviton Manufacturing, and GE, as well as ABB (Switzerland), Legrand and Schneider (both based in France), and SMK Corporation (Japan).
Demand is driven by both residential and nonresidential construction spending. The profitability of individual companies depends on manufacturing efficiency and effective distribution. Large companies have advantages in economies of scale in purchasing, production, and distribution. Small companies can compete by offering niche products.
