The return conductor, also known as the neutral, is grounded to the electric panel and is at what voltage?

The neutral wire, or return conductor, is intentionally grounded at the electrical panel, which establishes it at zero volts relative to the ground. This grounding ensures safety and stability in the electrical system, preventing the neutral from carrying a potential voltage that could pose a shock hazard.

In a typical residential electrical system in the U.S., the voltage supply typically consists of 120 volts (from hot to neutral) or 240 volts (from hot to hot). However, because the neutral is bonded to ground, any potential electrical voltage on the neutral should be negligible, hence it is considered to be at zero volts. This is crucial for maintaining proper circuit functionality and ensuring that devices operate safely without risk of electrical faults.
