=== === Yes but it is redundant. The only place that you can open the neutral and hot wire at the same time in a North American system is when isolating a load in an explosion proof installation All the rest of the time the neutral remains unswitched. A two pole switch is used on 240 volt loads as code states that both legs must be disconnected from the load. If only one leg is disconnected there will still be a 120 volt potential on the load to ground. <><><> As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

Can you feed a 208v 200amp panel from 480v 20amp circuit?
Not directly, you would need to transform 480v circuit to 120v with a transformer first.
Why is the main switch connected in series together with the rest of the circuits in the house?
It is connected so that it can disconnect the entire power grid in the house with one switch. This switch is usually integrated into a circuit breaker. No matter how one looks at it, this switch must be made to withstand (and be able to switch) great currents (in excess of 16A) at relatively high voltages (120V/230V). Special care must be taken during the design phase, as the switch will most likely have to suffer severe arcing as well as heating, during normal operation.
Can you use a 240V disconnect switch for a 120V AC?
Yes and you will have a spare terminal for future use
Is there a way to install a 277V light on a 120V circuit?
no ----------------------------------------------------------------------------------- Stepdown transformer. More expensive than buying the correct light fixture. Y-THINK-Y
Is number 10 wire good for a 20 amp circuit that is 250 feet?
Assuming you are working with 120v, you need #4 AWG copper conductors.
Is it right to connect 250V - 3A switch in the mouse circuit?
A: That would be OK ONLY if the switch is to carry 3 amps maximum meaning 120v AC or approximately 40 watts
what is the resistance of circuit with 120v and 10A?
12

What is the voltage of a series circuit with four voltage drops of 30 volts?
there is 120V across the circuit.
What is high voltage circuit breaker?
High voltage the switch blade must be long enough to break the arc low voltage means a smaller switch low amperage means smaller wire and contacts 120V 1/2" switch 13,200V 18" switch vacuum switches can be made smaller since there is no air to ionize
How do I connect a single pole 220v switch to a 3 wire 220v motor using 2 hot wires plus 1 ground?
Is it a single pole switch, or a (220)240v switch? A 240v switch is a double pole switch. It has 4 screws and disconnects both hot sources simultaneously.If it's a single pole 120v/277v switch, that just means you can use it on 120v or 277v circuits. If it's not a double pole switch with 4 screws, it's not the right one. Get a 240v double pole switch for this. You can usually find these at home improvement stores.When you state that the motor is a "three wire" make sure that the phasing is correct and you are not trying to connect up a three phase motor.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energizedIF YOU ARE NOT REALLY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.

Can a 120V double pole switch be used to switch a 240V air compressor?
There are no double-pole 120 volt switchesYou may be mistaking a four-way switch for a double pole. This device won't perform to serve your application.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
In a 120V 24A circuit what amp fuse is needed to protect it?
30 amp
Could 12 gauge wire is used on a 20 amp circuit at 120V?
Yes.
Have 30 amp double pole need 15 amp 120v?
Remove the 30 amp double pole breaker and install at least one single pole 15 amp breaker. It is best if the other slot is not left open so if you have another single pole breaker of any size install it in the 2nd spot so it isn't open when you replace the cover on the panel. For your 15 amp circuit you need #14 gauge copper wire or larger with a hot, neutral, and ground. Your 30 amp circuit was probably wired with #10 gauge conductors. These will probably work on your 15 amp circuit but it may be difficult to connect #10 conductors to devices.
