In most office environments, a typical reading of neutral-to-ground voltage is about 1.5V. If the reading is high (above 2V to 3V), then the branch circuit might be overloaded. Another possibility is that the neutral in the panel is overloaded.

Why does my neutral wire have voltage?

The wire used in electrical distribution systems is usually made of copper. ... When the wire length from the breaker panel to the service outlet is long and the connected equipment is pulling a large amount of current, the resistance in the wire will cause a voltage drop along the NEUTRAL wire.

Is there voltage on the neutral wire?

In the electric power grid, "neutral" is ground, by definition. So the voltage of the neutral wire is always zero... By definition.
