Electrically operated power circuit breakers vs. manual
Electrically operated power circuit breakers vs. manual
(OP)
We are installing new 480 Volt switchgear. There are large motors and motor control center feeders fed from it. There is a choice between electrically operated and manually operated power circuit breakers. Is there any advantage of getting the manual circuit breakers? The engineering firm is recommending them for the motor control center feeder breakers.

Only but for the grace of god there wss no one injured or killed. It would have been so easy that day to have lost someone. So as you can imagine Im all for getting out of the way of the switching and having it remotely done.
Remember the fault energy availiable is pretty high right at the transformer incomer.....
