Historical Note: Prior to the 2014 NEC, high voltage was defined as over 600 volts, but the threshold was raised to 1,000 volts in the 2014 and 2017 editions to reflect innovation in equipment standards
College and university campuses distribute electric energy in tranches of 10 to 250 megawatts; typically at voltages above 1000 VAC and are generally regarded as load-side services (or regulated utility customers). Two fairly stable sections of the National Electrical Code set the standard of care for these systems — Part III of Article 110 and Article 495.
We will examine them during today’s High Voltage Electric Service colloquium.

We collaborate closely with the IEEE Education & Healthcare Facilities Committee which meets online 4 times per month in European and American time zones. Ahead of the August 2024 public comment deadline we will examine transcripts of technical action on this topic:
