I got my Master Electrical License when I was in my twenties. Source of pride because they weren't required in 117 of 120 counties in KY back than. Kept them up and continued education for thirty years. I made a living calibrating and maintaining GE current , voltage, watt and synchronizing relays in power plants for last twenty years. Now most of these relays have been replaced with programmable microprocessors and engineers with laptops do most of the programming. Nobody I work with even worries about keeping their license up anymore or knows what the logic they just downloaded even really does in effect to relay logic anymore.Power plants are ran on a need to repair only in case of shutdown status because of the winds of change constantly changing directions these days.
