Yes, if there in no ground wire that is acceptable on a home with no ground wires.
It shouldn't. The open end of a non connected neutral should have the same potential as the voltage feeding the circuit. The only time a voltage will show is when the return neutral is tested with a meter to the neutral bar or the ground return bar. It will then show what the supply voltage to the connected load is. Once this neutral is connected to the neutral bar there will be no voltage shown across the test meter between the neutral and the neutral bar or the ground bar.
Because the white wire on a 120 volt circuit is the neutral wire that is connected to the silver screw on outlets and switches. It is connected to the neutral bar in the service panel.
The neutral wire and power wire are never connected together.
In the US, the common usage of these colors is: BLACK: Hot - connected to one phase of the service AC. WHITE: Connected to the Neutral of the service AC. GREEN: Connected to the GROUND bus at the service entrance. At the service entrance, the GROUND and the NEUTRAL bus are connected together.
In most electrical devices the neutral wire is connected under the silver coloured screw.
You should never switch the neutral wire. The neutral of the appliance should be connected directly to the neutral wire leading to the service panel neutral bar.

Answer for USA, Canada and countries running a 60 Hertz supply service.Yes, the neutral is connected to a system ground in the main distribution panel.
You can not have a "neutral earth" the "neutral" and the "earth" are separate wires/connections and should not be cross connected or muddled up.
A phase leg connects to the neutral through the connected load.
As far as I understand, you don't need neutral line for connecting appliances that is 3-phase compilant. You only need the neutral line to connect a single phase appliance, which you connect along with one of the three lines.
Because the white wire on a 120 volt circuit is the neutral wire that is connected to the silver screw on outlets and switches. It is connected to the neutral bar in the service panel.
If the hot is connected to the supply and it is turned on and the switch is turned on and the neutral not connected this could be quite true. Connect the neutral to the supply neutral and shut the switch off. Now the only reading that you should get is the hot supply.
A delta-connected system is described as being a three-phase, three-wire, system, and doesn't have a neutral. But a balanced star (wye) connected load (e.g. a three-phase induction motor) doesn't actually require a neutral.
if you look on the transmission, you should see two wires connected to the neutral switch.
The neutral wire and power wire are never connected together.
In a three phase system, connected wye, neutral is the common return, and it is grounded. In a delta connection, there is no neutral.
