I work in an industrial facility that was built in the 70's and really didn't follow the NEC for the most part since then. It wasn't under OSHA regulation until the last 5 years. So I have been there for around 4 years and being a licensed electrician I feel an obligation to upgrade to current code. I realize it isn't realistic to start fixing all the problems at once but feel that if I go to work on something and it doesn't meet code that I should upgrade it. For instance if I go to change a bad motor and find it has undersized wiring, no overload protection and on a circuit with other motors or loads then I think it needs to be upgraded. Is it my responsibility to upgrade? Since we are OSHA are we required to upgrade? I really have a hard time to ignore the problems. Please give some input. Thank you.
