Which is the safest position for the switch to turn an appliance on and off?
the safest position for a switch is on the live wire and not on the neutral wire
Why is it always connected in the phase or line wire to the switch and not 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?
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.
How do you hard wire an appliance?
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.
Why is it unsafe if the live wire and the neutral wire are the wrong way round?
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.

What do I attach the house white neutral wire to if my Maytag electric cooktop has no neutral wire?
Just cap the white wire off and fold it up in the back of the box, out of the way.
How can I test the neutral wire in an electrical circuit?
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.
Is the wide part on a plug positive?
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.
How can I determine the location of the neutral wire in an electrical circuit?
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.

Is a common or Neutral wire needed for all 240 volt circuits Example will a 240 volt electric motor run without a Neutral wire?
Answer for USA, Canada and countries running a 60 Hz power supply service.It all depends on the type of appliance!Some 240 Volt appliances, such as some electric motors, DO need to have a Neutral wire. Some of these appliances have timers or other devices inside them which only require a 120 Volt power supply, hence they need a Neutral wire to get that.Other appliances, for example some household electric clothes dryers, DO NOT have to use a neutral wire because they only have a very simple heating element connected just to the red and black "hot" legs of the supply. (One hot leg is actually 120 Volts above Neutral when the other leg is 120 Volts below Neutral. But remember, as this is alternating current, they both alternate 60 times a second, going from zero to +120V to zero to -120V and back to zero again.)However a dryer should always have a Ground wire connected to its metal casing to protect users from possible electrocution and prevent a house fire. Such a ground wire helps ensure that the circuit breaker or fuse will cut off the power supply if a fault occurs within the appliance or its power outlet. (But that has nothing to do with "needing" a connection to a Neutral wire.)IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.If you do this work yourself, always turn off the powerat the breaker box/fuse panel BEFORE you attempt to do any work ANDalways use an electrician's test meter having metal-tipped probes(not a simple proximity voltage indicator)to insure the circuit is, in fact, de-energized.
How can I determine how to find a neutral wire in an electrical circuit?
To find a 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 close to zero. This wire is likely the neutral wire. Be sure to follow safety precautions when working with electricity.
