High, medium, and low voltage are the terms we hear the most when talking about voltage classifications. From an international standpoint, these classifications and ranges change depending on where you live. In the United States, the National Electrical Code (NEC) and the National Electrical Manufacturer's Association (NEMA) have guidelines and standards that cover all voltage classifications. The American National Standards Institute (ANSI) oversees the creation, promulgation, and use of thousands of guidelines and standards that affect businesses. Each industry complies with applicable regulations.

Both the ANSI and the NEC code are publications that are purchased. The Electrical Engineering Portal (EEP) produces a breakdown of ANSI standards C84.1-1989. This document divides voltages into five classifications. These classifications can be combined into the categories below:
High (HV), Extra-High (EHV) & Ultra-High Voltages (UHV) - 115,000 to 1,100,000 VAC
Medium Voltage (MV) - 2,400 to 69,000 VAC
Low Voltage (LV) - 240 to 600 VAC
Generac issued a white paper titled Medium Voltage On-Site Generation Overview. The white paper compares NEC to ANSI Standards. It sites the following NEC voltage standards:
High distribution - 1000 to 4160 volts
Medium distribution - 50 to 1000 volts
Low distribution - 0 to 49 volts
The above lists illustrate the classification of voltage level changes depending on the governing authority. Generac states that generators less than and equal to 600 volts are medium-voltage and generators greater than 600 volts are considered high voltage. Generators producing 4160 volts are common in many industries for large motors that require high voltage. The backup generator supplies voltage to an individual grid.

Commonly stocked generator voltages are 4160 VAC, 480 VAC, 12,470 VAC, and 13,800 VAC, when power fails to an industrial facility, the backup generator supplies power to distribution and control panels for continued operations. The higher voltages from the generator are stepped down with transformers. The below content supplies information on each category of information.
