What does line voltage mean?
Simply so, 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.
In respect to this, 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.
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 vac = vab - vcb or, adding the two voltages as vac = vab + vbc. The notation for these differences in voltage can let you calculate phase to earth voltage.
