Wall outlets, also known as electrical sockets or power points, are devices installed in walls that provide access to electrical power. They allow users to plug in various appliances and devices, such as lamps, chargers, and kitchen equipment, to draw electricity from the electrical grid. Typically, wall outlets come in different types and configurations, depending on the region and electrical standards. Most outlets have two or three holes for prongs, which connect to the plug of an appliance. Safety features, such as grounding and circuit breakers, help prevent electrical hazards and ensure safe usage.
