What is this receptacle called?


A wall receptacle is a location on a wall where an electrical appliance may be plugged in. The majority of receptacles have either two or three holes. The two-hole models accommodate an electrical plug with a live connection and a neutral connection; the-three hole models take plugs with a third ground connection. There are different power regulations in different countries; as a result, there are different styles of wall receptacles. This will prevent accidental exposure to the wrong electrical current, avoiding damage to the appliance and reducing the chance of fire.

Even though the appearance of wall receptacles may vary, they are all built basically the same. Most models have two or three holes, and each hole has a specific purpose. One hole is for the live wire, which carries the current from the wall to the plugged-in item. The other hole in a two-hole system is for the neutral—it carries power back to the source. On the three-prong system, the third hole is for a...

An electrical outlet is also known as a receptacle. A receptacle outlet is an electrical outlet with one or more receptacles installed. Most modern homes have receptacle outlets. The most common of these is the duplex receptacle outlet. It has two identical outlets, usually stacked one on top of the other.

Most homes have dozens of receptacles, and most of these are grouped into receptacle outlets. The most common outlet used in the United States is the 120 volt. This outlet includes three holes.

One small rectangular hole conducts electricity through the plug to the device being powered. This is known as the hot slit. The other rectangular hole is neutral. The two rectangular holes are placed parallel to each other. Below these an arch-shaped hole takes the bottom prong of the plug, which grounds the device.

The common receptacle outlet is made of two or more of these 120 volt receptacles. Receptacles are inset in the wall and wired into the electrical system...

After some experimentation, I have a solution that I think will be useful to others. I go into some detail here, so that people can take the principles and adapt them to their own circumstances. A lot of it seems obvious in retrospect, of course!

Tools I used:

Two long plastic yardsticks (wood or fiberglass would be fine, too). One small plastic binder clip (like the ones used for potato chip bags). One high-powered flashlight. (Optional for other circumstances: a piece of plywood)

First, here are some questions that capture the underlying principles that I puzzled out.

How can I have fine-grained control over rotation of the plug parallel to the wall, so that I can properly orient the ground pin and prongs clockwise/counter-clockwise relative to the receptacle?

How can I control rotation of the plug perpendicular to the wall, so that the prongs and pin are properly facing the receptacle?

While maneuvering the plug, how can I detect when the...

As was said in the first answer, the ratings you give are the highest that watts and volts that the receptacle will endure before melting from the heat. No house in the US will have that amount of electricity running to it. Why, because normal house light bulbs seldom go above 150w, 120v. What you must be concerned about is the amperage being used. In the US, houses are usually wired with a 14 or 12 Gage wire to the receptacles for lights, TVs, stereos, etc. Some "lighting only" circuits could be run with 14 Gage wire since the amperage pull would be below 15amps. The outlets in the walls of most rooms are usu sally run with 12 Gage to allow for larger amp pull for TVs, VCRs, etc placed on one circuit. This will allow for 20 amps of power. Since you are dealing with light circuits, either receptacle can be used. Addendum: If the light comes on when you reset the breaker and stays on until you turn off the light at...

Receptacle Doesn't Work

By far the most common problem with a receptacle is that it doesn?t work. Because receptacles are very inexpensive and easy to replace, it makes sense to replace them when they cease to work properly. But before you go to the trouble of buying a new one and installing it, make sure that the old one is truly defective. For a non-working duplex receptacle, first make sure the problem isn't with the appliance or lamp. Some appliances, such as hairdryers, have overload protectors that automatically shut them off if they begin to overheat. Try a second appliance or lamp in the receptacle. If the receptacle still doesn't work, you'll usually find that the circuit breaker has tripped or the fuse has blown, the receptacle has become faulty, or there is a switch that operates that receptacle and it needs to be turned on. The problem is rarely the wiring. 1) Test the receptacle with a second lamp or appliance. 2) Be sure that one half of...

Receptacles (electrical outlets) that have only two slots are called polarized receptacles. These have a smaller "hot" slot and a larger neutral slot, ensuring that the electrical currents flow along the appropriate wires in the circuit; hot along hot, neutral along neutral. All modern plugs have corresponding wide and narrow prongs, or blades so that you can plug into the receptacle only one way.

This is all part of a safety system that's been in wide use since the 1920s. Receptacles today have three slots--hot, neutral, and ground--and accept three-prong grounded plugs. When properly wired, this provides a reliable ground system that is safer than the older systems with polarized receptacles.

The Importance of Grounding

Grounding is a safety system that provides a path for electrical current to flow to a safe destination if there is a problem with a circuit. For example, if a wire comes loose from a receptacle and touches the side of a metal electrical...

the hot wire side enters the appliance and the neutral is connected to the other end of the appliance circuitry, when the polarity is reversed the appliance circuitry is electrically charged all the time, but only functional when a switch closes the neutral wire connection and the current begins flowing.

The diagram below illustrates the difference in reversed polarity with a toaster. When wired correctly, the circuit is energized only up to the open switch (left). But, with reversed polarity (right), the entire circuit within the toaster is “live” up to the backside of the switch.

So, the heating element wires in a toaster (the ones that turn red) would shock you if you stuck a knife in the toaster with reversed polarity to prod a piece of toast loose. Also, the metal shell of the light bulb socket in a lamp would cause a shock if touched when the polarity is reversed. Both of them are harmless if the wiring is correct.

An organ or structure which receives a secretion, eggs, sperm, etc.

‘This dance would last no more than 10 to 15 seconds, and from what I have read the male at this point inserts his sperm packet into the receptacle below the female's mouth, using his specially modified tentacle.’ ‘Females mate with multiple males and store the collection of sperm in the seminal receptacle and the paired spermathecae for later use in fertilizing eggs.’ ‘During copulation, he deposits sperm into her sperm receptacle and places a plug in it, perhaps to retain his sperm or prevent other males from mating with her.’ ‘If all goes well, the male lobster soon embraces his mate firmly, assumes a posture suggestive of the missionary position, and deposits his sperm inside an egg receptacle near her...

General features

The broad range of variation in the morphology and structure of nonreproductive (vegetative) organs within the angiosperms has been outlined above. There is a similarly broad range in the morphology and structure of the reproductive organs of the plant.

Many vegetative buds sooner or later become flower buds. Flower buds are modified leaves borne on a short axis with very short internodes and no axillary buds. The floral axis has determinate growth, in that at some point it ceases to grow.

Flowers, the reproductive tissues of the plant, contain the male and/or female organs. They may terminate short lateral branches or the main axis or both. Flowers may be borne singly (as in the daffodil and Magnolia) or in clusters called inflorescences (e.g., bromeliads, snapdragons, and sunflowers). Fruits are derived from the floral parts of the angiospermous plant.

A complete flower is composed of four organs attached to the floral stalk by a...

Before I talk about the self-test GFCI receptacle, it’s important to know what a GFCI is. If you don’t know what a GFCI is, then you haven’t read our GFCI blog! Shame on you! It’s okay, we forgive quickly here at KB Electric LLC. So here is the short definition: GFCI stands for Ground-fault Circuit Interrupter. Basically, it is a device (like an outlet, also known as a receptacle) that can detect when an electricity current is flowing through an unintended path, like water or through a person. When this detection occurs, the power to the GFCI outlet will shut off, preventing electrical shock from occurring. Please visit our GFCI blog for more detailed information as to why it’s important for your home to be grounded and equipped with GFCI receptacles.

What Is A Self-Test GFCI Receptacle?

A self-test GFCI receptacle is a receptacle that regularly tests the ground fault circuit interrupter function by itself, and then cuts off the power to that receptacle when the...

When does a ground fault occur?

A ground fault occurs whenever electricity escapes the confines of the wiring in a light fixture, appliance, or power tool and takes an alternative unintended path to the ground. When that alternative path is through water or a human, the results can be fatal.

Did you Know That...

About 200 people in the United States die from ground faults each year. This number accounts for two-thirds of all electrocutions that occur in homes every year.

How to eliminate ground fault accidents?

In order to eliminate the possibility of these ground fault accidents, Charles Dalziel, an electrical engineering professor at the University of California, invented the ground-fault circuit interrupter (GFCI) in 1961.

A Ground Fault Circuit Interrupter, better known as a GFCI or GFI, works by measuring the electrical current leaving the hot side of a power source and comparing it to the current of the returning...

Flower heads have a large urn-shaped receptacle with whitish, tomentose phyllaries tapering toward the tip.

The line pin is on the left when looking at a receptacle with the earth pin offset down.

The receptacle consists of a spongy network of arms interlaced to make meshes of unequal size.

A receptacle used in pressure frying is known as a pressure fryer.

Seminal receptacle is small, pouch-like, positioned near ventral edge of albumen gland slightly anterior to bursa copulatrix.

Phyllaries are either free or more or less fused; the receptacle presents typically flat, but naked.

The flowers are distinctive in that tepals arise from a disk-shaped receptacle rather than the usual tube.

Two 120 volt devices may be plugged into a duplex receptacle that connects one neutral wire to both outlets.

A threaded cap atop the stem on the lower half provides access to the receptacle for the remains.

Connectors are used on electrical wiring harnesses and are essentially enclosures (i.e., shells) which house contacts with wires. The electrical connection into the system at the contact termination is either a soldered or crimped connection (which is removable from the connector using a special tool). The shell and insert may be moisture resistant or a hermetic seal. The inserts in each connector must be oriented for correct mating, and the shell or insert usually contains a keying feature to prevent mis-mating that could damage the connector or result in an electrical problem.

Connector plugs and receptacles most commonly used for military aircraft were developed in the 1930s. They set the standard for the modern Military Standard (MIL-STD) and Military Specification (MIL-SPEC) connectors. One of the biggest challenges in assembling electrical harnesses is providing the correct connector plugs and receptacles for each reference designator of an electrical...

Is it a receptacle or is it an electrical outlet? These terms are really interchangeable, but are often confused by the DIYer. This article reviews the basics of the electrical receptacle or outlet, the common types found in the home, and how to make the correct purchase when replacing an electrical outlet.

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). The best definition of an outlet or receptacle is “an opening or series of openings connected to a wired power source meant to power electrical equipment and components”.

I had a reader comment on this post with some added information that I think you will find very uselful in helping to understand the definition of an outlet. The N.E.C. says: A point on the wiring system at which current is taken to supply utilization equipment. This will...

If an outlet (commonly called a receptacle) no longer holds a plug snugly, it should be replaced. The procedure for replacing a duplex (two-outlet) wall receptacle is similar to that of replacing a switch. The only difference is that, depending on where the receptacle is located in the wiring scheme of your house, it may have more wires attached to it than you find attached to a light switch.

Look closely at the terminal screws of the new duplex receptacle. On each side of the receptacle is a pair of terminal screws. The upper screw is connected to the upper outlet, and the lower screw services the lower outlet. A thin, metal break-off tab connects these screws. This tab enables you to attach a single wire to either screw and feed electricity to both outlets of the receptacle. If the tab is broken off, you can connect the upper and lower outlets to separate wires and control them independently.

If the receptacle is wired to...
