Hello guys and gals.
Im going to keep this long story short. Got a piece of equipment (480V 200A) that has several motors with VFDS. About once per day, a breaker trips and causes one of the drives to go into a fault. The breaker trips because a piece of glass gets turned wrong in the glass crusher causing an overload. This is a recycling center. Someone has to open the panel door and reset the breaker and clear the fault on the drive.
The question brought to me by a new manager was why do they have to call an electrician to have this reset. There is no electrician on sight sometimes, so they have to call an electrician in another division. This can take an hour or so for them to arrive. The whole line shuts down when this happens.
I told him, IN MY OPINION, that as long as the person was an authorized person he could reset the equipment. I defined an authorized person to him as to someone who is properly trained in the equipment and aware of the dangers that may be present. I also told him that the proper ppe should also be worn.
He was under the impression he had to have a licensed electrician to do it because this is the way they always did it in the pass.
Was I wrong by telling him this? I am not up to par on the OSHA laws or NFPA70E like I should be. Could you reference the place in these codes that prove me right or wrong?
Thanks for the replies.
