Hi,
I have recently purchased an old workshop that used to run three-phase, and have come across an old contactor with some sort of adjustable dash-pot, this pot contains oil with a small scale signed "TRIP AMPS" .
The contactor was part of wiring for a motor control (this controlled a roller shutter)
Now my question:
I have recently re-wound the motor so that it will work correctly with single phase, and would like to retain the old switch gear that controls it.
What would be the best way to test and measure the current "trip" setting on the contactor, as it does not show a real reading, just a rough estimate.
Also, what would be the best way to safely test the contactor, as i have never worked on oil-filled ones before ?
Thanks
Alan
