European single-phase electrical equipment, fittings and fixtures have wires colored as follows: Brown for 230 volts Hot (also known as "Live" in Europe) Blue for Neutral Green/Yellow stripes for Ground (also known as "Earth") Black and red are "hot" in single-phase 120V/240V wiring. In 3-Phase 120/208/277, the colors black, red, and blue are used. In 3-Phase 480V, the colors brown, orange, and yellow are used. The so-called "hot" leads are the wires carrying current to the load.
These colors are used simply as an easy way to identify which wires are the power feeders, and what voltage they are probably carrying. CAUTION: Never assume what wires are hot, or what voltage you are dealing with simply by LOOKING at the colors. Always use a voltmeter to determine this. Also, if you are in fact dealing with a Brown-colored wire, rather than Black, you may be dealing with up to 480 volts, especially if there are also an orange and yellow wire present. This voltage is usually used for motors. All AC voltage is dangerous, however, 480 volts is very dangerous. When using a voltmeter while testing unknown voltage, always set it on the highest voltage setting, which is usually 600V. Also, be sure it is set on the "voltage" reading if using a multimeter. You don't want to smoke these things, as they can be fairly expensive! <><><>
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

What else can I help you with?
Light switch has 4 wire colors red and white and green and black which is the hot wire?
You have a 3 way switch. Your black wire is the hot wire. Your green wire is the ground wire. Your red and white wires go to the light and other switch. You should have gotten a wiring diagram with your switch.
How do you wire a light switch with only black and red wires?
The black wire is typically the hot wire that carries the electrical current, while the red wire is often used as a traveler wire. Connect the black wire to one terminal of the light switch and the red wire to the other terminal. Make sure to turn off the power before wiring the switch to avoid electrical shock.
Is the red wire hot or common?
If wired correctly the red wire will be hot, but any wire can be hot regardless of colour if done incorrectly.
If there are a red wire a black wire and a bare wire in a 120 volt supply wire which is the hot wire?
Where there is a red wire involved that usually indicates some type of special switching arrangement or more likely a 240 Volt circuit. In this case there will be 240 volts across the red and black and they will both be hot. Normally for 120 Volts the black is hot, the white is common and the bare wire is ground.
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.

Which wires, red and black, are considered hot in the electrical circuit?
In an electrical circuit, the red wire is typically considered the hot wire, while the black wire is usually the neutral wire.
How do you wire a light switch with only black and red wires?
The black wire is typically the hot wire that carries the electrical current, while the red wire is often used as a traveler wire. Connect the black wire to one terminal of the light switch and the red wire to the other terminal. Make sure to turn off the power before wiring the switch to avoid electrical shock.
What color is a hot wire?
It should be RED. If not then black.
Which of the two wires is hot which is neutral?
If this is a home wiring question and the wires are black and white then black is Hot and white is Neutral. If you also have a red wire, it is the other hot wire, and either the black or the red wire to the white one would be 120 volts, and red to black would be 240 volts.
What color is the hot wire in an electrical circuit?
The hot wire in an electrical circuit is typically black or red in color.
Which wire is hot on a lamp cord?
The wire that is hot on a lamp cord is typically the one that is black or red in color.
Is the red wire hot or common?
If wired correctly the red wire will be hot, but any wire can be hot regardless of colour if done incorrectly.
My Windshield wiper motor stop working for my 1995 cutlass supreme. Can you tell me which wire is the hot wire and the ground wire?
Red is hot, black is not.

Have a black white and red wire for a dryer plug what ones the ground wire?
The green or bare wire is typically the ground wire for a dryer plug. If your wires are black, white, and red, the white wire is usually neutral, the black is hot, and the red is also hot. You should double check with a voltage tester to be certain.
