The Red wire is one phase leg "hot" and the Black wire is the other phase leg "hot" for standard 240 Volt household power supplies.
Using a voltmeter to measure ac (alternating current) voltage, from the Red "hot" wire to the White (Neutral) wire should measure about 120 Volts and from the Black "hot" wire to the White (Neutral) wire should also measure about 120 Volts. From Red to Black should measure about 240 Volts. A Green-insulated or Bare copper wire is the protective Ground wire. <><><>
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?
Which color wires for a power antenna are 12-Volt?
Typically, the blue wire is used to power the antenna and is connected to the 12-volt accessory wire on the car stereo. Make sure to consult the specific wiring diagram for your car model to confirm.
How can I install a 110 receptacle alongside a 220 receptacle using the 220 receptacle wires for power?
While you can physically do this it violates the Electrical Code. 110 Volt and 220 Volt receptacles are required by the Electrical Code to be on separate breakers for safety reasons, this would put them on the same 220 Volt breaker.
What color of wires are found on a 120 volt duplex poutlet?
A 120 volt duplex outlet is the main type of outlet for residential outlet system. The wires are typically white and black, and there should only be two of them.
Should a 220 volt wiring have a yellow wire?
Your local electrical codes will tell you what color the wires should be. In the United States, you should not see yellow wires in household electrical wiring. For 240V, you should either have two black wires or a black and a red, but once again that falls back on the local electrical codes. A yellow wire may be a white wire that is showing its age. If this is the case, then it should read around 0V to ground if everything else in the circuit is correct.
What do you mean by a 5 volt lamp?
lamp works on power of volt
What is the volt of standard atx power supplies?
12 volts
What color is power in the radio?
Normally red. Check the wires with a volt meter to be sure.
What household current do you need to power 460 volt motor?
There is no household current with which you can power a 460 volt motor.Normal US household power is 120/240VAC split phase. (Other countries have different configurations, but the answer remains the same.) Without a transformer, and a substantial power flow, you are not going to develop the voltage necessary to run a 460 volt motor. Even if you could generate that voltage, you still only have one phase available, and most 460 volt motors require three phase power.You could do this with an inverter, or a motor-generator set, but to be blunt, you are asking about a commercial application, not a household application.
What are the differences between 240 volt and 120 volt electrical systems and how do these differences impact the efficiency of household appliances?
The main difference between 240-volt and 120-volt electrical systems is the amount of voltage they provide. 240-volt systems deliver more power than 120-volt systems, allowing appliances to operate more efficiently. Household appliances that require higher power, like ovens and dryers, typically use 240-volt systems for better performance.
What are PowerPoints on ford trucks?
Those are the 12 volt power supplies and take a cigarette lighter adaptor
How much current flows in a 12 watt radio connected to 120 volt circuit?
A 120V household electrical outlet supplies 12 watts of powerwhen the current is 0.1 Ampere (and the power factor is 100%).
Can you wire a 12 volt power outlet into your cigarette lighter?
A power outlet can be wired int a cigarette lighter. The wires will have to be cut, with the power off. Then the wires will need to be connected back together while adding the power outlet wires. The Connection will have to be a proper connection, preferably with crimp connectors.
How do you connect your radio to a twelve volt battery?
connect the power and acc wires together and put them on the positive and the ground to the negative
Which wires are the positive and negative power window wires on a 2001 Nissan Frontier?
Positive is normally red and negative is normally black or green. Test them with a volt meter to be sure.
How many volt power supply instrumentation amplifier required?
it depends on if its household or portable, household would depends on where ur located in jamaica it would be 110v, for portability both here and abroad it would be 12-19v. i have a portable 800watt power for my household entertainment and its power supply is 12v, over 7amps.
What is a Variable 0 - 12V dc power supply?
A variable power supply has a control to adjust the DC output voltage from 0 to 12 volts. It is used for testing electric project's such as amplifiers and other electric devices. It can be used to replace other fixed voltages power supplies such as the srandard 3 volt, 5 volt, 9 volt and 12 volt units.
What is meant by 220 volts AC?
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.
