What do the three pins of a socket represent?
Three-pin plug and socket In a three-pin plug, the top pin is for earthing, the pin on left is for live and the pin on the right is for neutral. In a socket, the upper big hole is for earthing, the hole on the right is for the live wire connection and the hole on the left is for the neutral wire connection.
What are the parts of a 3 pin plug?
A plug consists of the case or cover, three pins, a fuse and a cable grip. The case of a plug is the plastic or rubber parts that surround it. Plastic or rubber materials are used because they are good electrical insulators. The pins inside the plug are made from brass because brass is a good conductor of electricity.
What are the three pins of a three pin plug?
The Three Pin Plug
- The LIVE wire is BROWN. This is connected to a fuse on the live pin.
- The NEUTRAL wire is BLUE. This is the route the electric current takes when it exits an appliance; it is for this reason the neutral wire has a voltage close to zero.
- The EARTH wire is GREEN & YELLOW. and connected to the earth pin.
What do the letters L and E stand for in a three pin plug?
Live, neutral and earth terminals in a plug are marked L, N and E respectively. © Eugene Brennan.
What is difference between earth and neutral?
The major difference between the two is that earthing provides you with a grounding point, that idle the current moves into the earth while the neutral provides you with a returning point for the flow of electricity, that is the electricity wire just returns back.
What are the prongs on a plug called?
The standard 3-prong receptacle is called a grounding receptacle because it allows a grounding wire to be connected from the electrical circuit to the appliance. The grounding wire is connected to the third prong of the plug.
What does each prong on a plug do?
The right slot (a narrower space) is for the hot wire, while the left slot (a bit wider) is for the neutral wire. When plugging a device into an outlet, the electrical current flows from the hot wire into the hot prong on the plug. Then, it travels from the neutral prong into the neutral wire.
Why do UK sockets have 3 pins?
The 3-pin plugs are designed so that electricity can be supplied to electrical appliances safely. Each wire has its own specified color, as shown above and each pin must be correctly connected to the three wires in the electrical cable.
What is L and N in electricity?
L is the abbreviation for “Live,” and N is for “Neutral.” Live refers to the phase or active wire that carries power in electrical wiring, while Neutral refers to the return path or inactive wire. The two wires are usually differentiated by color: black (Live) and white (Neutral).
What happens if neutral and earth touch?
In Short if neutral wire touches a earth wire, An earth wire carrying load current is a risk of electric shock because a person touching this earth may present an alternative path for the load current and thus the risk of electric shock.
