Plugs | Electrical Sockets
Plugs, electrical plugs, and electrical sockets provide electric equipment connection to the alternating current (AC) power supply in buildings and at other various sites and devices with power access. The plug is the mobile connecter that is a part of the electrically operated device, and the socket is on the equipment or building structure and connected to the electrical circuit. In the 1880s, plugs and sockets for portable appliances became widespread and replaced the connections to light sockets with wall-mounted outlets. Standard systems of plugs and sockets differ across the world, and as a result, electrical plugs and sockets are varied in voltage, current rating, shape, size, and connector type.
Installing a replacement electrical socket is simple. Install a replacement electrical socket by turning off the main power. Prepare the cables, strip the wires, and attach the Pigtail wires. Then connect the ground wire, and attach the neutral and hot wires to the receptacle. After attach the receptacle to the box and add cover plate over the electrical socket.
The line of an outlet is for the incoming power supply. The wires coming from an electrical panel should be connected to the line of the outlet. The load of an outlet is for power that is going out of the outlet. If you are installing other outlets, the other electrical wires should be connected to the load side of the outlet.
When you can’t tell if an electrical socket has power first try to plug in something else to see if the outlet works. If the electrical socket does not power anything it most likely has no power and its voltage should be tested with a multimeter. If no other electrical sockets are working it is most likely a problem with the circuit.
