No current flows in the circuit when the circuit is open, as in when the appliance is switched off. The voltage is on the "hot" side of the switch when it is in the open position but the neutral is not energized until the switch is closed.
the safest position for a switch is on the live wire and not on the neutral wire
because its much safer to switch the hot wire then the neutral wire because if you are working on a light fixture for example and the switch is off if you ground yourself out to the neutral you become the load or return. a neutral shock can me more dangerous at times
If an appliance is plugged in but the switch is OFF, the electrician should always consider the appliance as A. hazardous. C. safe. B. ungrounded. D. de-energized.
To hardwire an appliance, first ensure the power is turned off at the circuit breaker. Remove the appliance's cover plate to access the wiring compartment, then connect the appliance's wires to the corresponding electrical supply wires—typically black to black (hot), white to white (neutral), and green or bare to ground. Secure the connections with wire nuts or terminal screws, and then carefully tuck the wires back into the compartment. Finally, replace the cover plate and restore power at the breaker.
From a purely electrical perspective, most items will run just fine if the hot wire and neutral are reversed. I like to say the electrons don't care. But any protection built into a piece of equipment is wired into the hot wire and you subvert this protection if you reverse the wiring. In a light fixture, the NEC requires the neutral wire (usually white) be connected to the screw shell of the socket. This prevents the screw shell from being energized and it is the most accessible part when changing bulbs. If properly wired, the hot part of a socket is the "button" in the very bottom of the socket. There are some items that require proper wiring and the only way to ensure this is done is to do it right every time. Another way to explain it is, using a vacuum cleaner as an example, if the wiring is correct, the hot wire goes to the switch and only when the switch is on is the vacuum cleaner energized. If the wiring is reversed, all the wiring in the vacuum cleaner is energized even when the switch is off.

Just cap the white wire off and fold it up in the back of the box, out of the way.

To test the neutral wire in an electrical circuit, you can use a multimeter set to measure voltage. First, turn off the power to the circuit. Then, place one probe of the multimeter on the neutral wire and the other probe on the ground wire. If the multimeter reads a voltage close to zero, the neutral wire is functioning correctly. If there is a significant voltage reading, there may be an issue with the neutral wire.
What you are refering to is a polarized plug. The wide connector forces the proper orientation in the outlet. This is so that the hot and neutral connectors in the plug, match the hot and neutral (cold) prongs on the plug. This forces a switch to operate on the "live" or hot wire. If a switch interrupted the flow of electricity in the neutral wire, the appliance would still shut off but the plug itself will remain "hot" whcih is a shock hazard. No, the wide blade on a plug is the neutral connection.
To determine the location of the neutral wire in an electrical circuit, you can use a voltage tester or a multimeter to identify the wire that carries little to no voltage compared to the hot wire. The neutral wire is typically connected to the ground or earth in the electrical panel. Be sure to turn off the power before attempting to locate the neutral wire for safety.

To find the neutral wire in an electrical circuit, you can use a voltage tester or a multimeter. Turn off the power to the circuit, then test each wire to see which one has a voltage reading close to zero. This wire is the neutral wire. Remember to always follow safety precautions when working with electricity.

To wire an AFCI breaker, first turn off the power to the circuit. Then, connect the hot wire to the breaker's terminal, the neutral wire to the neutral bar, and the ground wire to the ground bar. Finally, snap the breaker into place in the electrical panel.
