An electrical outlet or receptacle is a socket that connects an electrical device to an electricity supply. In buildings, electrical outlets are usually installed in the wall, although they can also be installed in the floor. Different countries often have different outlet types and voltages.
What is the difference between a plug and a receptacle?
The difference between a plug and receptacle is that plugs have prolonged connecting pins which fit into a mating socket called a receptacle. A receptacle connector is sometimes called a jack. A receptacle will have mounting features such as a flange with holes.
Following voltage harmonisation, electricity supplies within the European Union are now nominally 230 V ±10% at 50 Hz. Historically 110 V, 115 V and 117 V have been used at different times and places in North America. Mains power is sometimes spoken of as 110 V; however, 120 V is the nominal voltage.
A DC connector (or DC plug, for one common type of connector) is an electrical connector for supplying direct current (DC) power. Compared to domestic AC power plugs and sockets, DC connectors have many more standard types that are not interchangeable.
A socket is something into which something is plugged or fitted (also called a receptacle). A light socket is called a light socket because a light bulb is inserted into it. A power outlet is called an outlet because power comes out of it.
And if you plug a single-voltage (120 volts for the US and Canada) appliance into a 220-240 volt outlet, even with a plug adapter, you'll "fry" it, because 220-240 volts is just too much for the appliance to handle. You could even start a fire.
220 volt outlets are the most powerful plugs that you'll find in most residential homes around the United States. These plugs are meant for ovens, dryers and other high-powered appliances that you simply can't power with a standard 110V outlet.
The common voltage in a U.S. home is rated at 120 volts. Except for a specialty outlet, such as for a stove, larger BTU air conditioners or some electrical clothes dryers, virtually every other wall outlet will be a polarized two-prong outlet with a third-prong grounding plug.
Another name for a receptacle is an electrical outlet. Electrical outlets or receptacles are often called plugs or plug-ins, but a plug is the proper term for the male cord end (that plugs into an outlet or a receptacle). Receptacle Outlet. An outlet where one or more receptacles are installed.
120/240-Volt Electrical Receptacles. 120/240-Volt Outlets. Providing both 120 and 240 volts, these receptacles have four plug-in slots—two that are hot, one that is neutral, and one that is grounding.
(Straight = Hot, L-shape = Neutral, Round = Ground) Appliances with 110 volt that pull more than 15 amps require a 30 amp outlet with 10 gauge wire and a Nema 5-30 plug. If 110-120 volt appliance is under 15 amps a regular 3-prong cord is used.
An electrical outlet or receptacle is a socket that connects an electrical device to an electricity supply. In buildings, electrical outlets are usually installed in the wall, although they can also be installed in the floor.
Not every electrical wire (and outlet) can handle higher voltage, such as 240 volts. But as it turns out, both the 120 volt and 240 volt alternatives can be beneficial, depending on your needs (and appliances). When 120 Volt Outlets Are Enough. Most everyday appliances only need enough electricity for a 120 volt outlet
Standard electrical outlets contain two 120 volt wires and one neutral wire that deliver power to items in your home using one phase of your electrical service. The 240 volt receptacles work differently. They use both 120 volt wires, a neutral wire, and in newer homes, a ground wire, to power a single receptacle.
220 volts 20 amps. This is a 220v 20 amp outlet as shown in the how to 220-volt outlet video likely to be used this for larger power tools in your garage or shop or perhaps a wall air conditioner.
Plug, socket & voltage by country
|Country / state / territory||Single-phase voltage (volts)||Frequency (hertz)|
|American Samoa||120 V||60 Hz|
|Andorra||230 V||50 Hz|
|Angola||220 V||50 Hz|
|Anguilla||110 V||60 Hz|
While standard duplex outlets feature two outlets under a cover plate held on by one screw, 2 duplex outlets feature four outlets under the same cover plate, held on by two screws. This configuration allows for up to four oversized plugs in close proximity.
The Type B electrical plug has two flat parallel pins and a round grounding (or earth) pin. The earth pin is longer than the other two so that the device is grounded before the power is connected. As with the type A plugs, the American and Japanese versions vary slightly.
Used in: Europe, with the exception of the UK, Ireland, Cyprus and Malta (see complete list of countries on the right) The Type C electrical plug (or Europlug) is a two-wire plug that has two round pins. It fits into any socket that accepts 4.0 – 4.8 mm round contacts on 19 mm centres.
Orbit Industries' Fixed Bar Hangers are used to securely install electrical and ceiling boxes boxes that are offset from studs or joists.
A GFCI is specifically designed to protect people against electric shock from an electrical system, and it monitors the imbalance of current between the ungrounded (hot) and grounded (neutral) conductor of a given circuit.
