Tomorrow night, 5/12/19; I have got a job at a southern water pumping station to investigate a seized isolator. The isolator is a 400amp 3 phase Harvey Hubbell from about 1960’s. it is stuck in the closed position. We are able to remove the Handle and take the door off to game access. Has anyone ever worked on such isolators or even seen them. I don’t have any pics to show you. I was just interested if people know anything about if they were easy to take apart and fix.
We have 2 hours to try and fix it or remove it and fix it back at our work. 2hours is all they can turn the power off to the station for, The isolator is fed by 95mm singles, so not huge by any means, but it dose come straight from a bus bar chamber. Hence why we also have a BTU guy and a Southern water opps guy to shut the station down.
