Have you examined the Electrical Settings dialog > General tab?
The parameter Electrical Data Style offers the following:
Connector Description Voltage / Number of Poles - Load
Connector Description Voltage / Phase - Load
Voltage / Number of Poles - Load

The parameter Circuit Description offers the following:
480V-3P/30A
480-3/30
3P30A
3P/30A

Do any of these match what you have in mind?
