Main Neutral is Breaker Panel Question

So, you are saying that voltage between the two green dots in the attached picture should be 120v, with the breaker off? Correct?

Not likely. As we said before, the current on your neutral is probably not from your service. It's from a neighbor's service, and it's coming in through your plumbing and leaving through your utility neutral connection. Check the current on the plumbing bonding conductor or your incoming water main. It's probably the same as the current on the neutral with the main breaker off.

Would this extra currect cause my meter to "turn" (it is one of the new digital meters and hard to tell if it is actually "turning")

The 2 green dots should show zero voltage.
Did you measure current from the top of the main breaker with the power off?
Did you check voltage from ground and neutral from the bottom of the breaker with the main off?
Have you checked your meter to see if it has any movement with the main off?

If he used a wiggy he might be showing voltage because of a light bulb installed and turned on.

With the breaker on. With the breaker off it should show 120 volts.

Fisher, you need the power company and or an electrician. This is nothing you are going to fix yourself. And it needs to be fixed. Start with the power company, they are free.

The voltage between the green dots is not a relevant measurement. With the main breaker on, it will be zero. With the main breaker off, it will probably be around 120 but might not be. It doesn't matter. The current through your neutral will not affect your power bill, since it doesn't pass through the meter. The problem is not in your house and there's nothing you can do to fix it. Only the power company can do it. You need to contact them and have them fix your neighbor's service neutral.

The voltage across a switch or circuit breaker or fuse is certainly relevant when trouble shooting. Seeing voltage tells us the device is open. Not seeing voltage tells us the device is closed. Reading zero volts across a breaker which is supposedly turned off indicates a problem. Or tells us the power is off.

Of course it's relevant to troubleshooting some problems, just not this one. He already knows the power is off.
