What are the 3 wires in a 3-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 does third pin in three pin plug indicates?
The earth pin or the 3rd- pin on a plug is generally bigger and thicker than the rest pins, probably the live and neutral pins allowing the earth pin to be the first to connect and the last to disconnect.
What are the three points of a plug?
Why do we use three prong plugs? A three prong plug is designed so that electricity can be safely supplied to electrical appliances. The third prong grounds the electricity to protect anyone who uses the metal-encased appliance from electric shock.
How do you wire a 3-pin socket?
If you want to connect a new 3-pin dual socket, just connect the “Earth” as Green with Yellow stripe color wire into the “E” screw terminal (which indicates Earthing & Grounding). Now connect the “Neutral” as Blue color wire into the “N” screw terminal slot (which indicates Neutral).
How does a 3 prong plug work?
When a 3-prong plug is plugged into the receptacle, the grounding wire is connected to the prong and provides a continuous grounding path from the appliance back to the breaker box. This grounding path serves as a primary safety means if there is a short circuit or other damage to the electrical circuit or appliance.
What does 3 lines mean in electrical?
Line with three wires. Line with three wires. Wire. The asterisk indicates the number of wires. Neutral wire.
How does a 3-wire circuit work?
A typical 3-wire circuit is actually two separate parallel circuits with a common conductor. If the grounded (neutral) conductor is opened, the circuit changes from two 120V parallel circuits to one 240V series circuit.
What is the third pin on a power cord for?
The third pin is the ground pin. It is supposed to be connected to the metal chassis of the device at one end and to earth ground at the other (plug-in) end. It is there for safety.
Why is it important to wire a 3-pin plug correctly?
It is important to know how to wire a 3-pin plug correctly. 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 the maximum current a 3-pin plug can tolerate?
Most 3-pin electrical socket outlets can tolerate maximum current upto13 amperes (A). It is imperative to ensure that electrical equipments can operate under these situations before putting their plugs into the electrical outlets. Almost all new electric appliances these days, come with a complete fitted 13 Amp 3-pin plug.
What does the third pin do on a neutral wire?
When you say “what does the third pin do”, I have to assume you mean ground. Neutral — Return path for electrons to the power plant generator (Neutral does not mean it is any safer than the Hot wire, it is the same wire just the return path.)
