Electrical contractor 37 years. Electrical inspector 2 years
In my opinion they better not be working on MCC buckets, 480 volts, 4160 volts or anything live with only 4 years starting from 0. Many plants hire unqualified people thinking that they can train them on the fly. With out any formal constant supervision and training they could pick up dangerous habits or wrong concepts, no matter how sincere the worker or the supervisor are. At the least they should be trained in NEC70E and LOTO. There is also a NEC code on plant maintenance. I am sure we all seen work done by a plant electrician that was very impressive but not done to code.
