What You Need To Know About Electrical Socket Types


You probably know about electrical sockets and sockets with USB ports, but you might be surprised by how many you can buy and install at home. There are typically seventy-five plugs available in a typical house. There are numerous other options besides the standard 3 pin socket and 15-amp socket. Each of these common electrical sockets serves a specific purpose, and you’ll need to know what they are if you want to work in electrical construction and maintenance.

  • The Most Common Electrical Sockets

Most of the houses have multiple types of sockets. However, some of them are described here. A car charger socket can effectively replace an electrical outlet, allowing for charging various electronics while on the road. Your car’s stereo and other electronics are hardwired into the panel that controls the electrical system.

  • 2-Prong Sockets

This type of outlet is widespread in older homes but needs to be improved in modern construction. It’s a two-prong, 15-amp, 125-volt outlet that doesn’t require grounding. It’s less secure than the more advanced three-prong option because it needs a ground wire. In addition, it is rapidly becoming irrelevant because of changes in construction regulations.

  • 3-Prong Sockets

This plug socket is by far the most typical in homes today. It superseded the previous standard, the two-pronged socket, for all domestic electrical connections. It’s a 15-amp, 125-volt outlet with a grounding prong added. It meets all the requirements of current building codes and is much safer than its predecessor.

  • GFCI Sockets

Legrand ground fault circuit interrupter plugs and sockets are very secure. Kitchens, bathrooms, and other wet areas with electrical sockets often have it. The socket monitors the wire current. A GFCI outlet will trip if an electrical surge or leak protects you. The socket’s two buttons test and reset the interrupter.

  • AFCI Sockets

A GFCI outlet resembles an arc fault circuit interrupter. It prevents electrical arcing, which can damage equipment. This circuit protection is needed because arcing can start fires. Circuit breakers in newer buildings have AFCI circuits. A special plug can retrofit older homes with this technology.

  • Recessed Sockets

These sockets have a connection point back into the box rather than flush with the wall plate. Therefore, fewer cables will protrude when plugging in electronics. Thus, you can store fewer items behind your furniture. This is common in living rooms and other rooms with hidden sockets.

  • USB Sockets

These plugs are equipped with USB charging ports. Thanks to the widespread use of USB-rechargeable smartphones, tablets, and other devices, their popularity is skyrocketing. The charging cable does not occupy a charger socket, which is a significant benefit.


A variety of uses can be found for electrical sockets. Electric connections are complete with sockets, wires, and pins, allowing industries to reap the full benefits. High-quality sockets are frequently needed for power generation because they contribute to efficient power transmission. Legrand’s universal socket is a single unit that can accommodate multiple types of AC plugs worldwide, eliminating the need for multiple power outlets.
