I believe you'd have to use a standard set of three way switches and a contactor. Tie the 120 volt coil to the three way switches and the 220 volt contactor to the load.Unless your talking about a 277 volt load, then you can use 277 volt switches.
Use a relayYou're probably better off trying to wire a separate 3-way switch circuit (at 110 or even 24 vAC) to control a heavy-duty relay that operates the 220-volt device.I cannot think of a scenario where you would. 240v in the US has 2 hot wires and, if there is a switch, both wires must be switched. What you need is called a disconnect, which is larger than a switch and in its own enclosure. These do not come in a 3-way configuration. A disconnect is not intended to be operated under load, which is with the equipment turned on.
I don't know if you are trying to ask if you can run a 240V panel off a GFCI or run a 120 V sub panel off of a GFCI. Can you clarify please,,,Thanks
No, the appliance is wired for a heavier circuit (240v). You wouldn't even be able to plug it in because the 240 plug and the 110 receptacle don't match. They're designed that way so they're fool proof.
It may not blow, but it will turn twice as fast and burn out very quickly. It is meant for 110 only. Check the sump pump. Some of them can be wired either 120v or 240v. If yours is like that, just wire the motor for 240v and plug it in.
a 30 pf capacitor is connected into a 240v, 60 hz circuit. what is the current flow into the circuit
Neutral is at the jumper that changes it from 120v to 240v. Two stator windings are used in series to make 240v; at that junction is (when wired in Series)your neutral/common/ground. Ground this terminal and use it for your neutral/common. When wired in parallel you have 110v and the jumper is removed and there is no common/neutral and ground is from the frame of the generator.
It would not be practical because the heater would likely require disassembly. If the heating elements are designed to operate on 120V and are wired in parallel, they could be instead wired in series to provide the necessary resistance. On the other hand, in the US, one could run a 240 line from the circuit panel to the heater and use a 240V breaker. The last option might be to install a step up transformer. In order to do this, determine the maximum current the heater will need then insure the breaker to be used is twice that capacity, and if it is, install the step up transformer and use the heater. The reason for twice the current is that when voltage doubles (120V to 240V) the current halves (40A to 20A).
No you can only have one dryer on a 240v circuit and nothing else can be attached to it either considering your using a 240v electric dryer

Yes it will operate it fine.

You DO NOT NEED A TRANSFORMER!!! You Have 220 Volts Commint Into Your Breaker Box. Install A 50 Amp 2 Pole Breaker And Run A Circuit With 6 Guage Romex Wire To The Stove. You May Need To Go Under The House Or Whatever To Reach The Stove But Do It This Way. You won't have the capacity
you are getting 120/240v to your house from your power company. this is considered single phase power even though two phases are used to get the 240v. any single phase to neutral (ground) will give you 120v. This is all wired in your load center in your house (fuse box) the wiring in your house is all wired in parallel, meaning that each circuit has the same voltage to it (either 120 or 240 depending on how it was wired) the resistance of the device plugged into the outlet will determine how much current is drawn by the device

Simple answer is yes. But you need to first determine if your breaker can handle it, not just because you have an empty slot. You have to total up amps being used and check rating for your box. If it can handle it then it is a sinch to install
Short answer: probably not. Longer answer: It depends on the size of wire feeding the stove, the stove amperage, and what you intend to connect to the new 15A circuit. If you just want to wire a light for the garage, sure go ahead. If you want to install a receptacle for a microwave oven, no way. Make sure you put a fuse to protect the circuit you are connecting.
