What should voltage be between neutral and ground?

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.

Why do I have 120 volts between neutral and ground?





If you have a neutral wire removed from the neutral bus bar in your panel it is possible to see 120VAC on that wire if the circuit breaker for that circuit is turned on and there is a load connected to the circuit and load device is also turned on.

Is 127 volts too high?

In fact, the same CSA recommendation defines 127 VAC as an “extreme operating condition”, just two volts higher than the top end of the “normal” operating range.

Why am I getting voltage on a neutral wire?

The voltage you are seeing on the neutral wire is conducting through that other load from the hot. Your voltage tester is detecting voltage without drawing current so the resistance of the other load is not seen. Try disconnecting/turning off all other loads on that circuit.

Why do I have voltage on my ground wire?

If the load increases drastically, a long wire between the breaker and service outlet can create a voltage drop along the neutral wire, leading to N-G Voltage when you measure the neutral voltage in reference to the ground.

Should there be 120v on neutral?





In a normal situation with the neutral path intact, you would have 120 volts measured from across the light bulb or the receptacle. In this case, both sides of the light (hot and neutral) are the same, thus no potential difference (voltage), and the bulb does not light up.

Why do I have 80 volts on my neutral?

Check voltage across each conductors. If you read 80V between the hot and neutral, and read 120V between the hot and ground. You have a malfunctioning neutral. If you read 80V between hot and both the neutral and ground your problem is with the hot conductor.

Does the neutral bar carry voltage?

Nothing happens if you touch a neutral bus bar. This acts as a conductor within the electrical circuit and does not carry voltage in a manner that would be harmful.

Can you be shocked by a neutral?

Do not touch even the neutral wire in a live circuit!



The neutral wire does have current going through it. However, we do not get shocked when we touch something with current going through it, we get shocked when current goes through us.

Can I touch neutral wire?

But its not safe to touch neutral wire! It is possible that the path to ground on neutral is not very good. When load is connected to the plug point the neutral may not always be at zero potential. Some voltage between earth and neutral(at a high potential) can give you a shock.

Is the neutral bar and ground bar the same?

At the service panel (ONLY AT THE SERVICE PANEL – HUGELY IMPORTANT) the neutral bus bar is bonded to ground. You should see the ground lead and neutral tied to the same bus (the neutral bus bar). Based on your description, it sounds like your panels are wired correctly.

Can neutral and ground be connected together in panel?



The answer is never. Grounds and neutrals should only be connected at the last point of disconnect. This would be at main panels only.

Do subpanels need to be bonded?

Rule #3: In a subpanel, the terminal bar for the equipment ground (commonly known as a ground bus) should be bonded (electrically connected) to the enclosure. The reason for this rule is to provide a path to the service panel and the transformer in case of a ground fault to the subpanel enclosure.
