Standard household voltage us

In the US , mains electric power is referred to by several names including household power, household electricity, house current, powerline, domestic power, wall power, line power, AC power, city power, street power, and electrical grid. In the UK, mains electric power is generally referred to as the mains. Believe it or not, there are standards here in the US.

The reason that you will most likely measure something slightly different at an outlet in your home is because of economic . Voltage in countries, list of mains plugs, voltages and frequencies for design engineers household energy distribution, European voltage and Hz, India.

Puerto Rico, 1V, HZ, USA.

The quick and simple answer is that circuits operating at higher voltage can do the same job with thinner (read: cheaper) wires.

It has been deemed necessary to increase voltage to get more power with less losses and voltage drop from the same copper wire diameter. These devices generally have chargers that are already compatible with any standard household voltage from 1volts in Japan, to 2volts in the UK. At the time (50s-60s) the average US household . The only national standard for utilization voltage regulation is ANSI C84. However, 1volts nominal may be referred to by equipment design standards as this is the Nominal Utilization Voltage as defined by ANSI C84.

National Standard for Electric Power Systems and Equipment – Voltage Ratings (Hertz). Volt: 1volts is the common lower voltage supplied by US and Canadian utilities. It is provided by the utility as 1volts ±. The US standard household circuit has an effective voltage of about 1volts, and voltage represents energy per unit charge.

Information about charging electronic devices and personal appliances while in the US. Standard electric plugs, as illustrated at the top of this page, have two flat blades. In countries in Europe and elsewhere, where 2volts is the general standard mains supply voltage for domestic houses, offices, factories, etc.

That power enters your home at about 2volts, that voltage is split at the main circuit breaker panel into two 1volt halves. Those 1volt halves are routed through the home to . The standard voltage and frequency of alternating current (AC) electricity used in homes varies from country to country throughout the world. A compromise was made in the U. V would come into the house where it would be split to 120V to power most appliances. House circuits are Supplied with AC. Electricity utilization typically happens at lower voltages - 3. Volts are common values for household electronics.

Why 60Hz is used in some parts of the world (primarily USA ) while 50Hz is used in others is because of historical artifacts that are not really cost effective to remedy.
