Unless the switch has a pilot light on it there is need for a neutral connection to the switch.
Yes <<>> In North America, a three wire 120/240 volt system uses a neutral wire. For 240 volts two "hot" wires are used with no neutral.
Answer for USA, Canada and countries running a 60 Hz supply service.To operate a 240 volt load in the home you use two adjacent breakers. This will give you a voltage of 240 volts where as one breaker to neutral will give you 120 volts.
On a 120/240 volt distribution the neutral is sized along with the supply conductors. The sizing is based on the amperage of the service distribution.
If you mean 110/240, yes, but there may be a hidden switch to switch it to 240 volt mode. Check the manual.
No, the voltage rating of the switch is too low.
Use a DPST - A two pole switch.
In residential wiring the white wire is neutral on the 120 volt circuits. On a 3way circuit the red is the traveler and the white is neutral. On a 240 volt 3 wire connection the white & black are hot. On a 240 volt 4 wire connection the black and red are hot and the white is neutral.
No. Not safe to do so. The distances between contacts may not be sufficient.
A 10 amp switch connected to a 240 volt circuit can carry up to 2400 watts (10 amps x 240 volts = 2400 watts). It's important to ensure that the switch is rated for the anticipated load to prevent overheating or failure.
A 240-volt circuit typically consists of two hot wires and a ground wire, with no neutral wire. The hot wires each carry 120 volts, while the ground wire is used for safety purposes. In a 240-volt circuit, the hot wires complete a loop by connecting to a load or device that requires the higher voltage to operate.
Question is incorrect. in a 240 Volt single phase circuit, how can you have A phase and B phase?
Power = Amperes x Voltage
