What are the 3 different wires in a plug?
The plug contains three wires – the live, neutral and earth wires. In a plug, the live wire (brown) and the neutral wire (blue) are the two wires that form the complete circuit with a household appliance. The earth wire (green and yellow) does not normally form part of the circuit and is included as a safety wire.
Does it matter what wire goes where on a plug in?
It matters where the wire goes because if you connect the hot wire to the neutral terminal and the neutral wire to the hot terminal, you will reverse the polarity, a phenomenon that can lead to electrocution. Outlets have black wire (hot), white (neutral), and green wires (ground).
Why do the wires in a plug have different Colours?
Fixed wiring electricity supply requires specific wiring colour regulations (bs 7671) to identify different power lines in different countries. The USA have their own wiring colours for electrical circuits, black, red, and blue are used for 208 VAC three-phase; brown, orange and yellow are used for 480 VAC.
Which wire goes in a 3 pin plug?
For a 3-pin plug, there are typically 3 different wires which need to be connected to the back of the plug. The three wires are the earth wire, live wire, and the neutral wire. These 3 wires come in a cable with different colors, which is done to distinguish between the three wires.
Why do some plugs have no earth?
Some appliances, such as vacuum cleaners and electric drills, do not have an earth wire. This is because they have plastic casings, or they have been designed so that the live wire cannot touch the casing. As a result, the casing cannot give an electric shock, even if the wires inside become loose.
Is black wire hot or neutral?
hot
Here’s a rundown of electrical wires: The black wire is the “hot” wire, it carries the electricity from the breaker panel into the switch or light source. The white wire is the “neutral” wire, it takes any unused electricity and current and sends it back to the breaker panel.
