:? Its my first time working with medium voltage.... 7200 Volts
I have an existing building with customer owned primary. It is an un-grounded system... Looking at 250 section X I am trying to figure out if I need to pull a grounding conductor with a new feeder I am installing. The run is piped 100% of the way with EMT from the switch to the new drycore 1500KVA transformer. Everything existing in the building has just the 3 cables pulled for each circuit, but this was also done back in the 60's.
Looking for some guidance.
