I'm guessing you want to know what a 240v switch is? If you look at a 120v single pole switch, you will see two brass screws on one side. This type of switch is designed to interrupt current flow in one conductor. A 240v switch is really a double pole switch. It has 4 screws and is capable (and required) of interrupting current flow in two conductors simultaneously. This is an NEC requirement. It allows a local means of disconnect instead of having to go back to the breaker, and a multiwire disconnect is required to disconnect all ungrounded (hot) conductors at the same time. That way one 120v leg cannot be shut off while the other is on. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB
SAFELY AND COMPETENTLY
REFER THIS WORK TO QUALIFIED PROFESSIONALS. If you do this work yourself, always turn off the power at the breaker box/fuse panel BEFORE you attempt to do any work AND always use a meter or voltage indicator
to insure the circuit is, in fact, de-energized.
What else can I help you with?
How many watts can a 10amp 240 volt switch carry?
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.
Can you install a 277 volt receptacle in place of a 240 volt receptacle?
No. To prevent this sort of thing from happening, the 277 volt device and receptacle is physically larger that a 240 volt receptacle and will not fit in a regular receptacle junction box. For a 277 volt system the proper size junction boxes have to be purchased.
Does a 120 volt light use less than a 240 volt light?
Not necessarily. The voltage of a light does not directly determine its energy consumption. The power rating of the light (measured in watts) will determine how much electricity it consumes. A 120-volt light may consume more or less energy than a 240-volt light depending on its power rating.
Can you install a receptacle that is rated for 240 volts to a 277 volt line?
No, the receptacle's rating is 240 volt and that is the maximum voltage allow to be applied to that device. To prevent this condition from happening 277 volt receptacles and switches have a larger box that they fit into. The retaining screws are set apart further that a 240 volt device which makes it impossible to install a 240 volt device in a 277 volt junction box.
How do you remove 240 volt light sensor and return to switch operation?
Remove the light sensor and place a switch between the red and black wires. The black wire is one leg of the "hot" pair and the load is connected to the red wire. This will now switch the black hot through the red wire that goes to the load.
How do you install a switch for a 240 volt motor?
Use a DPST - A two pole switch.
Where do you attach the neutral in a 240 volt switch?
Unless the switch has a pilot light on it there is need for a neutral connection to the switch.
Your medical machine says 110240 can you use it in a 240 volt system in cuba?
If you mean 110/240, yes, but there may be a hidden switch to switch it to 240 volt mode. Check the manual.
Can you use a 12 volt dimmer switch for a 240 volt ceiling rose?
No, the voltage rating of the switch is too low.
Can a 220V light fixture be used in the US?
Yes, you can easily use it. Just install it as you would any other 120 volt light fixture and change the bulb from a 240 volt bulb to a 120 volt bulb. It will work just fine.
Can you use a We Mo light switch on 240v?
The conscience is no. There is a work about by using an intermediary relay coil rated at 120 volts to switch the 240 volt feeder line.
Can a 240 volt switch be used on a 480 volt system?
No. Not safe to do so. The distances between contacts may not be sufficient.
Do you have to have a 220 v outlet even though you have a gas stove in michigan?
No, but if you ever switch to an electric stove you will have problems getting a 240 volt circuit to that location. I would go ahead and install a 240 volt outlet at that location if this is new construction. Costs very little and you will be all set for the future.
How many watts can a 10amp 240 volt switch carry?
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.
How can 240 vOLTS power a 277 vOLT light?
Slightly dimmly
Can you install a 277 volt receptacle in place of a 240 volt receptacle?
No. To prevent this sort of thing from happening, the 277 volt device and receptacle is physically larger that a 240 volt receptacle and will not fit in a regular receptacle junction box. For a 277 volt system the proper size junction boxes have to be purchased.
On a humid day the PLASTIC part of the light switch in your bathroom lights up a power tester It's 240 volts Is this dangerous?
the plastic part of the light switch should never show voltage especially if it's a 120 volt circuit. 240 volts is two 120 volt circuits the circuit might be connected to another circuit in the bathroom separating them will fix the voltage but you should also inspect and replace the switch.
