In this plant we have 3 complete different services coming into it,I'm talking meters and all.The building has walls breaking it into sections,
can we run power out of service 1 into a room and then come from service 2 or 3 into same room . I don't think they should be mixedor if they can what are the guide lines for mixing.
the service is 220 3 phase and 440 3 phase .
The voltages running into same rooms from different sources or 110 up to 440 single and 3 phase
