What is the voltage range for a house?
In actuality the range of the voltage coming into your house is typically between 110 and 120VAC. 105 to 125 is sometimes seen and this is probably acceptable to use; most appliances can accept this range even though for heating appliances for example, this can give a 40% difference is heating power.
What was the first power system?
The first power systems were 110 volts. Edison chose that as a good compromise voltage to make his light bulb work well (this voltage was high enough that the bulb gave off a good amount of light, but this voltage was not so high that it caused the bulb to burn out quickly).
When was the maximum deviation from standard voltage changed?
In the early 1970’s document C84.1 from the American National Standards Institute (ANSI) included a maximum deviation from standard voltage. In 1984 the NEC was changed so that the standard voltage used for load calculations was changed to 120 volts.
Is 115 a compromise?

What is split phase 240V?
In the United States, utility companies are required to provide a split-phase 240V feed to your house. This consists of two legs of 120VAC that are 180 degrees out of phase with one another. The picture below depicts one 120V leg in red and another in yellow.
What happens when you use both legs of a circuit?
When you use both legs to feed a circuit, like a range or water heater, you end up with twice the voltage (a line that oscillates from +240V to -240V). The neutral wire is not utilized in a 240V circuit as the current is fed by one leg and returned on the other leg.
How many Hz is AC?
AC power oscillates at 60 cycles per second (60 Hz) in the U.S. Other parts of the world use a 50Hz standard. The AC voltage oscillates from +120V to -120V. With the two legs feeding your house being out of phase, can you pick up 240V AC by using both legs rather than one leg and neutral.
