A standard two prong outlet in the US carries 110 volts. Actual voltage in your area may vary from below 100 to 140 volts, but these extremes are unusual. Most of the rest of the Americas (North and South) uses the same standard. In Europe, the standard voltage in a "two prong outlet" is 220 to 240 volts. In the US, this voltage is reserved almost exclusively for use by stoves and ovens in the home.

Why wouldn't a 2 prong plug fit in a 3 prong outlet?

The reason might be a voltage or amperage mismatch between the two devices. Plugs and receptacles are matched sets depending on the voltage and the amperage of the devices. The configurations are done in this manor to prevent the wrong voltages being applied to wrong plug in equipment.


Can you plug a 3 prong extension into a 110 volt outlet?

Yes, a 3-prong extension cord can be plugged into a 110-volt outlet as long as the prongs match the outlet. Just make sure the extension cord is rated for the appropriate voltage and current to avoid any electrical hazards.


How many holes are there on a standard 120 volt electrical outlet?

Usually 3. Why two different size prong? Two for the prongs and a third for the ground.


Does it matter how you plug in - are the two prong different?

For most standard two-prong plugs, there is no difference in which prong goes into which outlet. The prongs are typically the same size and shape, so it does not matter which way you plug it in. However, if the plug is polarized (one prong is wider than the other), make sure to plug it in the correct way according to the outlet.


What is a 220 volt outlet?

A 220 oulet line carries two 110 vold lines and a ground wire. The outlet is shaped differently than the standard household (110) outlet, usually having at least one (plug-in) prong 90 deg to the other, sometines two of the prongs. This type is usually found in a utility room for dryers, most of which use 220 power.
