What is LV current?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
LV stands for Low Voltage current, typically referring to electrical systems operating below 1000V AC or 1500V DC. In residential and commercial contexts, LV usually means:
- Household circuits: 120V-240V
- Safety considerations: Requires less insulation than high voltage
- Common applications: Lighting, appliances, electronics, and small motors
LV systems are safer to work with but require larger wire sizes for high-power applications compared to high-voltage systems.
