Guide to Low Voltage Distribution Systems | Maddox

A low voltage system is the final stage of the electric grid. It is the infrastructure that moves electric power inside buildings and dwellings. These systems rely on transformers to step utility voltages down to usable levels. The most common voltages found in such systems in the United States include 120, 240, 208, and 480 volts.

Difference Between High, Medium & Low Voltage Classifications

Factories that require medium or high voltage supply from the electric utility can have a dedicated sub-station. These substations step down voltages levels and distribute to buildings throughout the property. However, not all factories require high or medium voltages. Some require low voltages of 240, 480, or 600 VAC from utilities.
