High voltage > 1,000 > 1,500: Electrical arcing: Low voltage: 50 to 1,000: 120 to 1,500: Electrical shock: Extra-low voltage < 50 < 120: Low risk International Standard IEC 60038, IEC standard voltages, defines a set of standard voltages for use in low voltage and high voltage AC and DC . Understanding Low Voltage Systems. Low voltage systems refer to electrical systems that operate at a voltage level lower than the standard line voltage provided by the utility company. Typically, these systems operate at voltages ranging from 50 to 1000 volts. While they may not pack the same punch as high voltage systems . What is low voltage wire? “Low voltage” provides the ability to supply power to a wide variety of equipment and systems while minimizing the risk of electric shock. Typically, the range is defined as not exceeding 1,000 volts for alternating current (AC) and 1,500 volts for direct current (DC).
A mains transformer or backup generator distributes power to the switchgear by conductors or electrical connectors to an input fuse box or appliance, often an Air Circuit Breaker (ACB) or a Moulded Case Circuit Breaker (MCCB). Power is routed throughout the switchgear through inbuilt copper rods that supply lower-rated fuses, again ACBs or .GE - 5.3 Cu. Ft.
