FAQ:

Q: What is the voltage range in low voltage?

A: – 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

Q: What are low voltage products?

A: Low Voltage Products: Per ANSI standards, low voltage equipment is for use with nominal system voltages less than 1,000 volts. Medium voltage equipment is for nominal voltages greater than 1,000 volts and less than 100,000 volts. High voltage equipment is applied to nominal system voltages greater than 100,000 volts.

Q: What is the typical voltage for power lines?

A: In the United States, most power line voltage is standardized between 110 and 120 volts, though the actual power going into a home or building may fluctuate slightly. Most power companies try to ensure that their power systems provide no less than 114 volts of power and no more than 126 volts.

Q: What is low line voltage?

A: Low voltage lighting systems use a transformer to reduce normal line voltage (120 or 277 volts, usually) to 12 or 24 volts.
