# What does line voltage mean?

**Definition**of

**line voltage**. : the

**voltage**of a power transmission circuit or distribution circuit up to the point of transformation or utilization.

Correspondingly, what is line voltage?

**Line voltage** is the standard **voltage**—120 volts—that's found in outlets and junction boxes in the United States and Canada. Low-**voltage** lighting typically uses 12 or 24 volts and requires a transformer to lower the **line voltage** from 120 volts to avoid immediately burning out the low-**voltage** bulb.

Secondly, what is line voltage and line current? **Line voltage** is the **voltage** measured between any two **lines** in a three-phase circuit. Phase **voltage** is the **voltage** measured across a single component in a three-phase source or load. **Line current** is the **current** through any one **line** between a three-phase source and load.

Secondly, what is line voltage vs low voltage?

It is standard in lighting, while “low voltage (12v or **24v**) lighting” is used less commonly. Line voltage lighting systems typically use **120v** or 277v to supply power to lighting fixtures. Line voltage lighting systems do not require transformers to power lighting fixtures in many different applications.

How do you calculate line voltage?

The **line** to **line voltage** is the **voltage** or potential between two wires. For two **voltage** values that share a common wire, you can compare them as v_{ac} = v_{ab} - v_{cb} or, adding the two **voltages** as v_{ac} = v_{ab} + v_{bc}. The notation for these differences in **voltage** can let you **calculate** phase to earth **voltage**.
