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.
120 volts
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.
Yes - usually house voltage varies from 110 to 120 volts.
Only if the cable going to your well pump is a three wire. The third wire could carry the neutral and you will have 120 volts from either 240 leg to the neutral.
Yes. Circuits in a home are 120 volts but people tend to call them 110 volt circuits. The 120 volts you read on the appliance is the maximum voltage the appliance can handle. The actual voltage you will read at any outlet will range from 110 to 120 volts.
The average voltage a house outlet will give actually depends on how far of a distance the house is from a transformer on the pole. If the house is fairly close to the transformer, it will probably give around 120 volts. However, if the house is a bit far from the transformer, it will probably give around 107 volts.

120 volts.
The voltage of 120 volts is more common that the lower voltage of 12 volts.
Answer for USA, Canada and countries running a 60 Hz supply service.To operate a 240 volt load in the home you use two adjacent breakers. This will give you a voltage of 240 volts where as one breaker to neutral will give you 120 volts.
12 Volts DC
One has an element designed to work on 120 volts, the other has an element designed to work on 240 volts.
120 volts 60 hz
120 volts
Typically residential voltage may range from 110 to 120 volts so there should be no problem.
No. A water heater requires a 240 volt connection and cannot be re-wired to run on 120 volts. There isn't enough amperage in 120 volts to power the heating rods that are inside.
