Generally, black wires are live and white are grounded. However, it's a good idea to test this theory with a multimeter, not your fingers. In a Home/Residential environment, say a 120V outlet, there are three wires. Black is "Live" or "Hot". On an electrical outlet, it's the shorter pin on the right. White is "Neutral" it's the wider pin on the left. Green is always ALWAYS ground and it's the round-ish pin below the two flat pins.
Now, on a 240V outlet, such as an electric dryer, both wires are black, and both are live. This is because the alternating current on each wire is 120V relative to Neutral, but 240V relative to each other. (The voltage is 180 degrees out of phase). Both 120V and 240V are considered "Single Phase" power.
What else can I help you with?
White wire a black wire a red wire and a bare wire?
The white wire is typically neutral, the black wire is usually hot or live, the red wire may be a secondary live wire or used for a separate function, and the bare wire is typically the ground wire for safety purposes in an electrical circuit.
What is the red wire and what wire does it go with when there are three wires black red and white?
Red, white, and black are standard for a three-way switch (you have two switches that control the same fixture). You should also have a ground wire (copper, unsheathed). The black and red are negative, while the white is positive. It works pretty simply. When the switch is up, the black and white are linked, creating a circuit. When it is down, the red and white are linked. If both switches agree (both are red/white or both are black/white), then the circuit is completed and power flows.
12 volt pump with red and black wire which is live?
The red wire is typically the live wire for a 12 volt system, while the black wire is the ground wire. Always consult the pump's manual or manufacturer specifications to confirm the correct wiring for your specific pump.
What is significance of red black and green wire in three pin plug?
The significance of the red, black, and green wires in a three-pin plug typically corresponds to their functionality. The red wire is usually the live wire, the black wire is the neutral wire, and the green wire is the earth wire. These colors help to identify and properly connect the wires for safe and correct electrical wiring.
What is the color of live wire neutral wire and ground wire in Bangladesh.?
In Bangladesh, the live wire is typically red, brown, or black; the neutral wire is typically blue or black; and the ground wire is typically green or green with a yellow stripe. It is important to consult with a local electrician or electric code regulations for accurate information.

Where does the red wire go, to the white or black wire?
The red wire typically goes to the black wire.
Which wire does the red wire connect to, black or white?
The red wire typically connects to the black wire.

Is there a difference between black wire and red wire?
Yes, the red wire is a positive wire (+) and the black wire is a negative wire (-) :D
What is the proper sequence for connecting the black, white, and red wires in an electrical circuit?
The proper sequence for connecting the black, white, and red wires in an electrical circuit is to connect the black wire to the live or hot terminal, the white wire to the neutral terminal, and the red wire to the switched or load terminal.
12 volt pump with red and black wire which is live?
The red wire is typically the live wire for a 12 volt system, while the black wire is the ground wire. Always consult the pump's manual or manufacturer specifications to confirm the correct wiring for your specific pump.
What is significance of red black and green wire in three pin plug?
The significance of the red, black, and green wires in a three-pin plug typically corresponds to their functionality. The red wire is usually the live wire, the black wire is the neutral wire, and the green wire is the earth wire. These colors help to identify and properly connect the wires for safe and correct electrical wiring.
Is the white wire in the thermotat a neutral?
the thermostat has a black(line) wire to it, and a red wire going to it. the red wire then connects to the neutral wire. the black and red are like a leg switch.
Does the red wire go on the plus sign on a battery or the minus?
The red wire is Positive, (+) and the Black wire is Negative. (-)
What is the color of live wire neutral wire and ground wire in Bangladesh.?
In Bangladesh, the live wire is typically red, brown, or black; the neutral wire is typically blue or black; and the ground wire is typically green or green with a yellow stripe. It is important to consult with a local electrician or electric code regulations for accurate information.
How do you connect timer white and black house wire with red black and white wires?
To connect a timer to a white and black house wire with red, black, and white wires, typically the black wire from the timer connects to the black house wire, the white wire from the timer connects to the white house wire, and the red wire from the timer connects to the red wire from the house. It's important to follow the manufacturer's instructions and turn off the power before installation.
