Thankful For PI EMS
Got to work this morning to find the coach with no power. Looks like we dropped one or two legs of our incoming 3-phase power. Sitting in the coach now with the genset and AC running, waiting for the electrician to arrive. Our neighbors in the adjoining suites are rocking and rolling, so likely it's our transformer.
The EMS display in the coach registered 93VAC. So glad I got it installed and that it did its job.
