I clawed ,earned my way out of "maintenance" into a licensed master electrician and have went back to maintenace as a primery job ,still own and operate Buzz Electric. Here gos , not tring to piss anyone off but i won't hire an "Electrician" for maintenance, they don't useally have the general machine controls knowledge, troubleshooting skills and even basic problem solveing skills that i believe a maintenace man should have. I am not knocking the trade at all,cuz i also won't hire you if you don't have an electrical back ground.And besides a good electrician will also understand hydrualics easly, you can't have to much education,they also can't take it from you.
