To The Defense of Maintenance Electricians who are not Licensed. And I am not speaking of all of them, only the ones who take their Job seriously. A good M.E. knows his plant like the back of his hand. He knows what the electrical system is in his particular plant. He takes pride in keping the system well maintained to insure minimal disruptions to production. A good M.E. will also employ the help of appropriate engineers etc when needed. I have more then once seen Licensed Electrical Contractors come into a plant, goof off and do substandard work and charge outrageouly to the dismay of the M.E. Here again I am NOT knocking all Licensed Electrical Contractors, I know most of them are reputable in their trade and charge fairly. I'm just saying a Good M.E knows the system in his plant a whole lot better then an outside contractor.
