General Electric makes and sells refrigerators that use 220 volt electricity. They are manufactured for use overseas, but are sold in the US as well.
No the voltage is too low and besides the plugs are of a different configuration.
110
No, the compressor& fan will run too fast and will more than likely be damaged. It may not be damaged but I would not take a chance.
nothing
Yes
Yes, no problem.
Do not do this.
No.
It is certainly unsafe.
No. Attempting to run an appliance on insufficient voltage can cause damage to the appliance and can be dangerous. Call an electrician and get him to install a 220v plug
Yes because it is of a higher rating. But make sure your equipment can take the rating too.
Is the 220V plug 220V only or 110/220V? (The former will have 3 prongs and the former will have 4) If your case is the latter just use the ground, neutral, and one of the hots. This will give you 120V single phase. If the case is the former you can't get 110V off that plug.
Only if it is rated for 110V-220V. If it is rated for 110V only and you plug it into a 220V outlet, your device will be destroyed.
