Kinda-sorta.
It won't break, but it won't get particularly warm either.
If the supply voltage is Vs and the equipment voltage is Va, then the equipment will work if Va = Vs (equation). But if Vs / Va = 220 / 120 (equation) the equipment will fail.
No. It would have to be wired for 220 volts and would have to be rated for 220 volts and would have a different configuration so that a typical 120 v plug wouldn't fit the outlet.
Because it is a 220 volt outlet instead of a 120 volt outlet. Now, if this is a standard 120 volt outlet that is reading 209 volts then someone has made a mistake in the wiring. You need to call an electrician to straighten this out.
What is your question? A standard outlet is 110V. A 220 outlet is shaped different so that you know it is 220. You would never run 220 through a 110 outlet.
Alternating current. 120 volt in North America, 220 volt in the rest of the world.
Seeing that the question comes from North America the most common duplex receptacle has 110 - 120 volts potential to ground. The second most common potential difference is 220 - 240 volts. These voltages are obtained from a 120/240 volt system common to home connections from the local utility companies.
No, in North America the plug configuration will not allow that to happen. The blade configuration for 120 volts are in parallel where as the 220 volt configuration are in tandem.
No. Car stereos run on 12v DC power. A wall outlet, depending on where in the world you are, gives out either 110-120 or 220-240v AC power.
LCM of 120 300 and 220 is 6600.
220
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.
Although both options exist, it would seem that the vast majority of electric chair lifts require a standard outlet. The outlet, however, must be grounded (three prongs).
