What Is a Wall Socket?

A wall socket is an electrical outlet that receives plugs to allow electricity to flow into appliances.wall socket A wall socket may be a single socket on a power strip, or multiple sockets on a plug-in power board. Electrical sockets usually have two or three pins, and are rated for a certain amount of current and voltage.

Sockets are sometimes used in combination with extension cords, which allow the use of an appliance in locations where a socket is not easily accessible. These extensions may be used for laptops, televisions, or other electrical devices. A wall socket may also be the receiving end of a surge protector.

The designs of plugs and sockets have been developed to reduce the risk of electric shocks from contact with energized parts. For example, sockets are often recessed, and plugs are designed to fit closely within the recess to reduce the risk of the user accidentally touching the pins inside the socket. In addition, the plugs' contact pins are sheathed with insulation over part of their length to prevent contact with bare metal.

There are fifteen standard types of mains electrical sockets, designated by letter designation, that are recognized by the International Electrotechnical Commission (IEC). They differ in their dimensions, number of contacts, and voltage and current ratings. A socket that accepts two parallel pin slots is a duplex outlet, or double wall socket; a three-pin plug has a third grounding pin to prevent polarity reversal.

In addition to socket types, there are a number of different plug shapes that have been developed to prevent accidental contact with live wires inside the socket or power cord. For instance, many plugs feature a "flap" that covers the contacts when the plug is not in use to prevent unwanted contact.

The type K electrical plug features two round pins with 4.8 mm diameter and 19 mm center-to-center distance, and a U-shaped earthing pin. The design of the socket prevents polarity reversal, and it is rated at 16 A. Type K sockets are usually used in Switzerland and Liechtenstein.

A new outside socket can make it easier to plug in external devices, and it will eliminate the need for extension leads. However, it is important to select a socket with the correct IP rating for your home. You should also choose a socket that has RCD protection, which will ensure that any external devices that are plugged into the socket are protected against electrical faults and shocks.

When installing a new outside socket, you should always consult an electrician to ensure that the installation is completed to the highest standards. It is also important to purchase the socket from a trusted retailer, such as B&Q, Wickes or Screwfix, so that you can be sure it has been safety tested. Do not buy cheaper unbranded alternatives online, as they may not be as safe and could cause a fire hazard in your home.
