Depends. Typically red is hot and black, however on an automotive stereo its typically yellow to +12, red to ignition/accesory +12, and black to negative
In US household electrical service there are two "hot" 110 volt wires and one ground. Only one hot wire is connected to a normal outlet or light fixture. To wire a 220 volt alternating current outlet, both hot wires are connected to the outlet. This is used for appliances that need more power than is provided by 110 volts like electric ranges, clothes dryers, air conditioners.
The ground is always hot on summer because at this season of the year the distance between the sun and earth is so close that the sun-rays reach the surface and warm it up continuously.
They make cool burrows in the ground when it gets too hot!
If the two wires are on a parallel feed you would read the current through the parallel feeders. If the two wires are "hot " to the load and return back from the load the meter will read zero. The two magnetic fields that surround the wires when a current flows through them will cancel each other. As a result of this there will be no magnetic induction induced into the sensing coil of the clamp on meter.
When metals (like the copper in the telephone wires) gets exposed to heat, they expand (thermal expansion) and when the get cooled they shrink. This directly implies that cables are longer in summer when it is hot. So telephone wires are longer in the summer.
The different colors of wires used in electrical installations have specific meanings. Red wires are typically used for hot wires, white wires for neutral wires, green wires for ground wires, and black wires for hot wires as well.
The standard outlet wiring colors used in electrical installations are black for hot wires, white for neutral wires, and green or bare copper for ground wires.
Common colors used in old house wiring are black, white, and red for hot wires, and green or bare copper for ground wires.
hot wires are black, white wires are ground
I'm not sure if this is the same but the ground wire going to the stereo is not really ground! Try running the hot wires for your new stereo right to the fuse box or straight to the bat and see if that cures it. I had a problem that was very similar but it wasn't a Tacoma.
In electrical circuits, white wires are typically used as neutral wires, green wires are used as ground wires, and black wires are commonly used as hot wires.
ground is the black...
Hot and ground( red=hot green=ground)
In home wiring, hot wires are typically colored black or red, while ground wires are usually green or bare copper. In computer wiring, ground wires are typically black, while hot wires are often colored according to industry standards, such as red or yellow.
No, it is not safe to use a hot wire that is either black or white in color. These colors are typically used for neutral or ground wires, not for hot wires. It is important to follow proper electrical wiring codes and guidelines to ensure safety.
Common wire colors found in old house wiring include black, white, and red. Black wires are typically used for hot wires, white wires for neutral wires, and red wires for secondary hot wires or switch legs.
To fix reversed hot and ground wires in an electrical circuit, you should first turn off the power to the circuit. Then, switch the wires so that the hot wire is connected to the hot terminal and the ground wire is connected to the ground terminal. Finally, turn the power back on and test the circuit to ensure it is working correctly.
