What does a blue wire mean?
Blue wire generally refers to a type of wire or cable that is added to a hardware product at a factory in order to resolve design problems. Blue wires are also known as bodge wires in British English.
Which wire is the live wire and neutral?
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.
What are blue wires used for?
Blue wires are used as travelers, usually on three- or four-way switches (controlling a light from multiple locations) or as switch legs for things such as fans or lights. Yellow wires are almost always used as switch legs for outlets, fans, or lights.
What happens if you put live wire in neutral?
In house wiring this would be called a direct short (circuit) and would blow the fuse or circuit breaker. If the live wire enters directly into the neutral wire is a short circuit condition.In case of wire burns or normal wire, then circuit breakage and all things become normal except this conductor or wire.
How can you tell the difference between a live and neutral wire?
LIVE WIRE The live wire is connected directly to the generators of the electricity supply company.It carries current at high voltages (about 220−230V). NEUTRAL WIRE The neutral wire returns the electricity to the generator after it has passed through the appliance. The neutral wire completes the circuit.
What color is neutral wire?
white
What do the Different Color Wires Mean? 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.
Does blue wire go to white?
Blue wire is for the lamp if one is included with the fan. White wire is neutral. Green wire is for the ground. Red wire is sometimes included and acts as a conductor to carry power to the light kit.
Can a neutral wire shock?
So even the current returns through neutral (only from a connected load that completes the current flow circuit) you touching the neutral with a 0V cant get you a shock. But its not safe to touch neutral wire! It is possible that the path to ground on neutral is not very good.
What are the colors of a neutral wire?
The neutral is white, the hot (live or active) single phase wires are black , and red in the case of a second active. Three-phase lines are red, black, and blue.
Can a red wire be linked to a black wire?
You can link two red wires together, or you can link a red wire to a black wire. Since red wires conduct current, they are considered hot. Blue and yellow wires are most commonly found in commercial buildings and are used as the live wires pulled through a conduit.
What’s the difference between hot and black wiring?
Black Wires: Hot. Black coating is always used for hot wires. The term “hot” is used for wires that carry a live electrical current. These wires may feed a switch or an outlet and are often used as switch legs.
When to use blue and yellow electrical wires?
Thus, both hot and neutral wires have the potential to shock and injure you. Blue and yellow wires are sometimes used as hot wires inside an electrical conduit. Rarely are blue and yellow wires found in NM cable. Blue wires are commonly used for travelers in a three-way and four-way switch applications .
