If that’s the case, it’s about 14,000 to 17,000 volts into the transformer and about 600 volts coming out of the transformer.

A transformer that was buried underground goes all the way to the commercial building. Perhaps you’re wondering how it will come inside the 4-way conduit plastic to the disconnect.

If this is the case, the disconnect has the necessary volts. And from there, it will go to the CT cabinet. Because of the higher average in the voltage, it needs to be metered.
