Electrical Power Supply Industry Definitions
In the electrical power supply industry, 'low voltage' most commonly refers to mains voltage or power transmission lines. "Low voltage" in this context still presents a risk of electric shock, but only a minor risk of electric arcs through the air.
The International Electrotechnical Commission (IEC) defines supply system low voltage as voltage in the range 50–1000 V AC or 120–1500 V DC.
- British Standard BS 7671:2008 defines supply system low voltage as:
- 50–1000 V AC or 120–1500 V ripple-free DC between conductors;
- 50–600 V AC or 120–900 V ripple-free DC between conductors and Earth.
