maybe I was misinformed,but in a similar plant we had to different services coming in and they ran power all over the plant .The company wanted to add a large sub panel so we called in a large contrating company {electrical } and they told us we could not mix the services up and he was paid a gob of money to run new circuits and keep them in same room.When he was finished room 1,2,3
was from service #1 and room 4,5 were on service # 2. This where I am confused as what you guys are saying is maybe the old company I worked for may have been taken if there is nothing wrong with mixing
