Right inside the main panel where the Neutral and Ground Busses are bonded together, the voltage between the two (effectively across a short circuit) is near ZERO. HOWEVER as you get further from the panel and Neutrals and Grounds and Hots are all in paralell theres like a capacitor (capacitor effect) with possible voltage between two ends of a capacitor.

Similar, the voltage from Neutral to mother earth is near zero at the panel since the grounding electrode conductor (No 4 bare copper wire) is connected to the Neutral which leads to a grounding electrode (like a driven rod into earth). HOWEVER as you get downstream with Neutrals in paralell with hot conductors mutual inductance (transformer effect) plus the capacitance referred to above can all yield a Neutral voltage higher then mother earth.

Also old fashioned analog meters and newer digital meters yield different results subject to their input impedance and how they work, I love my old Simpson 260 analog in these applications. An "ideal" voltmeter has INFINITE resistance so it doesnt draw current and affect the true voltage between the test points.

Sure the 3 way switch (two single pole double throw switches) is wirede correct???

There is an old style 3way switch setup that can cause that effect?

I've got it in my house, 1930s setup.

When I had a new breaker box put in, my stairs lights were glowing at night, told the electrician the next day, and he said oh, the old style. He flipped the neutral and hot wires, and took care of it. He said those old type, makes a difference which side gets hot, but didnt elaborate.

For over 50 years I know of ONLY ONE way to wire them using two SINGLE POLE DOUBLE THROW SWITCHES. Each THROW wires to the other switches THROW (runners),,,One POLE wires to the branch circuits hot voltage SOURCE, The other POLE wires to the LOAD. Maybe there was an OLD way before I first learned how to wire them or different then single pole double throw switch use????

Fun chat, wish I knew an old versus a new way???

There is an old way. It was used to run a yard light on the pole between the house and barn. It used one less wire and powered from both the house and the barn.

Not a very safe because if one was going to work on the light and turned off the power at one end he didn't realize it was still hot from the other end.

I think is was called Chicago Loop.

Not legal today. I can't quite remember how to wire one that way, and don't want to.

Ain't no such thing as two way. Single, three way and four way.
