What Colour is wires for plugs?

What are the three wires in a UK plug?
The UK mains supply is connected to appliances in the home by using 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.
What are the colours of 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 do the different colors of electrical wire mean?
You’ll find yellow wires used in fixtures like lighting and ceiling fans. Blue Wires – always assume they are live if you have power. Blue wires are also fed through a conduit, usually bringing power to three or four-way switches. Green Wires – green wires are grounding wires.
Why do UK plugs have 3 pins?
Prong Design: Like standard U.S. grounded plugs, the U.K. wall plug has three prongs. The U.K. plug is designed so that the grounding prong is slightly longer than the prongs responsible for transferring current.
What are standard wire colors for 480 volts?
277/480 Volt AC Wire Colors. These higher-voltage systems are common for industrial motors and equipment. Phase 1 – Brown. Phase 2 – Orange. Phase 3 – Yellow. Neutral – Gray. Ground – Green, Green with Yellow Stripe , or Bare Wire .
What do the colored wires in outlet indicate?

What is the color code for wire?
Color Codes. Typically, the zero volt or ground wire is black, the +12-volt or +5-volt wire is red and the sensor wire — also known as the tachometric, signal or revolution wire — is yellow. In some cases, both the +12- or +5-volt wire and the signal wires are yellow. The signal wire may also be white, especially in fans made for Dell computers.
