Electrical Power Socket Connection Diagram and Wiring Procedure


The electrical socket is a female connector that caries the power source or power supply and transfer the electrical energy when an electrical plug is connected to it. Generally, the power source is connected to the power socket or electrical. Electrical sockets are used in switchboards, outlets, extension boards, etc. Electrical may be a two-pin or three pins or five pins. Electrical sockets come in many different ratings, styles, and designs. The most usable and common ratings of electrical sockets are 5A, 6A, 16A, 32A, etc. Single-phase sockets have either two ports or three ports. There are different types of ports also available. Some power sockets have flat ports some have round ports.


Electrical Power Socket Diagram and Terminals


Here, you can see a diagram of five-pin power socket.

Five-pin power sockets are come with 6A, 16A, 32A all of the current ratings. Some five-pin sockets have the function to connect both types of 6A and 16A plugs. On the front side, you can see all the five ports. The earthing or grounding ports is very bigger in size than other ports. If any short circuit fault occurs a very large current flow in the circuit. That is why the grounding or earthing pin is made bigger in size, as it can easily bypass the high short circuit to the ground. Also, you will be noticed that when you connect a power plug into a socket, the earthing pin is first connected to the socket then phase and neutral. This is done because, if there is any fault or leakage current is available, it will easily deliver to the ground, so it can reduce the chances of accidents such as electrical shock.

If you see the back side of the socket, you can observe there are three terminals with screws to connect the power supply - Phase, Neutral, and Earthing. Also, there will be an identification for all the pins. The Phase terminal is identified by either 'P' or 'L'. The Neutral terminal is identified by 'N'. And the earthing pin is identified by the standard earthing or grounding symbol.

As per the electrical standard, the switch must be placed on the right side of the socket. If your switchboard has multiple power sockets with individual switches, then all the switches should be placed at the right side of their respective power sockets.

Connection Procedure


1. Connect the earthing or grounding conductor to the upside earthing pin of the power socket.

2. Connect the neutral wire of the power source to the neutral terminal(identified by 'N') of the power socket.

3. Connect the phase terminal of the power source to any one terminal of the switch.

4. Connect another terminal of the switch to the phase terminal(identified by 'P' or 'L') of the power socket.
