Legrand, through its Pass & Seymour product line, brought the first GFCI (Ground Fault Circuit Interrupter) receptacle to market in 1972, revolutionizing electrical safety. While Professor Charles Dalziel patented the technology in 1965, Legrand commercialized it for residential use to detect faults and prevent electrocution. They continue to expand their role as a global leader in electrical and digital building infrastructures, with 160 years of innovation behind them.
