Why Is White Wire Connected to Ground?

Neutral: The white wire is called the neutral wire

neutral wire
Definitions. Ground or earth in a mains (AC power) electrical wiring system is a conductor that provides a low-impedance path to the earth to prevent hazardous voltages from appearing on equipment (high voltage spikes). ... Neutral is a circuit conductor that normally completes the circuit back to the source.

. It provides the return path for the current provided by the hot wire. The neutral wire is connected to an earth ground. Ground: The bare wire is called the ground wire.

Why is the neutral wire connected to ground?

Commonly the neutral is grounded (earthed) through a bond between the neutral bar and the earth bar. ... The connection between neutral and earth allows any phase-to-earth fault to develop enough current flow to "trip" the circuit overcurrent protection device.

What happens if you connect neutral to ground?

The neutral is always referenced to ground at one, and ONLY one, point. If you touch the neutral to ground anywhere else, you will create the aforementioned ground loop because the grounding system and the nuetral conductor are now wired in parallel, so they now carry equal magnitudes of current.
