Neutral Wire Has 120 Volts. 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 working as intended. If you touch it you would not get a shock unless some other part of you was touching something leaning on a defectively wired metal lamp where the line has shorted to the metal? This could be the case at a water well or a workshop.

The arduino is a great tool for anyone interested in inside the plugduino you'll find just a few basic bits that are wired together to make the magic the i/o status indicators display which outlets have power applied to them, and which inputs are generating. If units of electrical power are measured in watts and watts = volts x amps, then a current flow of zero volts of going to equal zero units (watts) of electrical power, no matter how many amps? He had taken off the wire nut for the neutral wires as part of his testing, and that's when, to his surprise, he got a shock from the neutral!
He had 120 volts on both sides of a switch (turned on) feeding a light fixture, but the light wasn't working.
Doug lowe still has the electronics experimenter's kit his dad gave him when he was 10. Each 120 and 240 require two wires to complete circuit. Neutral is normally two or more white wires covered with wire connector and add black tape when white wire carries voltage (applies to 208 and 240v circuits) with 120 and 277 volt circuits, white wire is neutral, and. A neutral wire is required to install leviton decora. These 230volt loads have one line fed by. Household wiring design has two 120 volt hot wires and a neutral which is at ground potential. Three phase four wire delta. He had 120 volts on both sides of a switch (turned on) feeding a light fixture, but the light wasn't working.
