Is 120 volt a regular outlet?
A standard 120V outlet contains a 120 volt wire and a neutral wire, and preferably a grounding wire. A 240V outlet has two 120 volt wires and a neutral wire. Older homes often have three prong 240 volt outlets, but modern outlets have a ground wire and four prongs.
What was the voltage of the 110 volt system?
The 110 volts system meant that about 100 volts would actually be delivered to the point of use. By the 1930’s the voltage had increased to 115 volts. (I don’t really understand why — I just know that it happened.) In 1968 the National Electrical Code (NEC) finally changed the values for motor rat.
What is 120/240?
Voltage of 120/240 comes from a standard single phase system, with two hot legs coming from the transformer, each being 120 volts to neutral, where the AC sine waves are 180 degrees out of phase.
What is the voltage of a Wye 3 phase system?
In commercial situations where you have three phase power, the voltage is typically 120/208 Wye system. There are still situations where you can have a 3 phase Delta service and you would have 2 phases to ground at normal 120 and ...
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.
When was the maximum deviation from standard voltage changed?

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.

How does voltage affect AC?
The higher the voltage, the harder the electricity pushes on a circuit and the more electricity flows through it. AC is also measured in frequency–how fast it changes direction.
How fast does AC change direction?
AC is also measured in frequency–how fast it changes direction. Most AC power is at 60 hertz, which means that it changes from negative to positive to negative again 60 times a second. Types. Most of the United States uses electricity at anywhere from 110 to 120 volts AC.
Can an electronic device run off AC?
Most electronic devices can not actually run off of AC current. Instead, they need steady, low-voltage DC power. That is why nearly every consumer device that plugs in has a DC power supply. The power is first run through a second step-down transformer to lower it from 120 volts to some value usually between 5 and 20.
Standard Household Voltage
