What is the standard outlet voltage in a house?

110 volt
The most common electrical outlet in any home is a 110 volt. Sometimes you may hear 110 volt plugs referred to as 120 volt.

What is the US voltage rating?

120 volts
In US homes, the standard voltage is rated at 120 volts, while a majority of European countries are rated at 240 volts. Interestingly enough, both US and most Europeans residential applications receive a distribution of 240 volts of power, but the way it’s configured differs.

What is a standard US outlet?

The standard voltage and amps in an outlet: Most homes in the United States are wired with 120-volt, alternating current circuits that use both 15 and 20-amps. The vast majority of outlets, however, use 15-amp receptacles. 20-amp circuits are for high-power appliances, like the fridge/freezer, or a dishwasher.

Why does America have different voltage?

So, to summarize, countries in North America adopted 110-120 volt AC to minimize the risk of injuries and fatality, but did so at the cost of forgoing power efficiency. Also, they adopted the 60 hertz frequency, which is optimal for AC transmission.

What is the standard voltage of a home electrical outlet?

The standard voltage of a home electrical outlet in the United States is 120 volts, although the actual voltage supplied may be as low as 110 volts, due to line conditions. A few appliances, like stoves and electric dryers, may use 240 volts, which require special wiring and outlets.

How much voltage can you get from a voltage rating?

Nominal voltage can vary up to plus or minus 5 percent from its stated definition. The outlets in your home are rated at the maximum voltage expected on the electrical circuit. They are designed to take up to 125 or 250 volts, depending on the nominal voltage of the circuit.

What is the voltage drop to the fartherest outlet?

Tuesday, June 19, 2018 The nominal voltage in the United States is 120 volts, but the National Electrical Code [NEC 210.19 (A)] specifies an acceptable drop of 5\% to fartherest outlet, which is 114 volts. The NEC does not specify maximum voltage, but plus 5\% is the accepted standard.

What voltage is the power delivered to my home?

The power delivered to your home is 120 or 240 volts. This is called “nominal voltage.”. That means it’s the standard voltage as measured at the transformer outside your home.
