FOR 90 YEARS... Ericson Manufacturing Company has been an industry leader that provides products for the safe use and management of temporary power and temporary lighting. From our first rubber hand lamp in 1918 (and our patent on the dead-front-back-wired electric plug and connector in 1936) to our portable GFCI (ground fault circuit interrupters), Ericson has built our reputation on the highest quality, state-of-the-art electrical safety products in the industry. MEETING THE DEMANDS OF THE INDUSTRY... Ericson does not try to force standard products into special applications. Instead, we can engineer and manufacture custom solutions for each client. We can meet the demands of virtually all temporary power applications, from general maintenance and confined space entry to hazardous location lighting, temporary power distribution and more. Ericson's Continuous Quality Improvements directly benefit our customers. Our products undergo rigorous testing to ensure that they meet stringent quality standards. But our goal is to go one step further: to constantly improve so that we may not just meet, but consistently exceed your quality expectations.
