The wire rating for a # 12 wire is 20 amps. If you are going to continuously load the circuit you need to de-rate the wire by 80%. This brings the current down to 20 x .8 = 16 amps. The wire rating of a # 10 wire is 30 amps. 30 x .8 = 24 amps.

What size wire for 110 volt 20 amp circuit 250 ft?
A #4 copper conductor will limit the voltage drop to 3% or less when supplying 20 amps for a distance of 250 feet at 120 volts.
My 250 volt wire to my Kenmore electric range shorted out with a large pop. I relaxed the 250 volt wire but range still doesn't work. What's going on?
When the wire shorted it probably burned through. You should employ a qualified electrician to help you troubleshoot the problem.
What circuit breaker to install for 10 amp 250 volt circuit?
You need a breaker rated for 10 amps and 250 volts. The breaker must also fit properly in your panel.
30 amps on a 250 volt outlet can handle how many watts?
A 30 amp circuit on a 250 volt service could handle up to 7500 watts. That's if it's actually 250 volts coming in. You should check that with your meter.
What size wire need for 70 amp at 250 ft?
#3 copper.
What AWG cable for 200' x 208 volt three phase 250 amp circuit?
A wire size of 250 MCM will limit the voltage drop to 3% over a distance of 200 feet.
What size wire for 110 volt 20 amp circuit 250 ft?
A #4 copper conductor will limit the voltage drop to 3% or less when supplying 20 amps for a distance of 250 feet at 120 volts.
What size service head is needed to power 250 amp 415 volt installation?
If you use 250 or 300 MCM wire you will need a 2 1/2" weather head. If you use 300 MCM wire then you will need a 3" weather head.

30 amps on a 250 volt outlet can handle how many watts?
A 30 amp circuit on a 250 volt service could handle up to 7500 watts. That's if it's actually 250 volts coming in. You should check that with your meter.
What size wire for 250 amps?
15mm approx.
Is there adapters for 250 volt to 120 volts?
No. There are no "adaptors". To get 240V from a 120v supply you use a 120-240V step up transformer. <><><> Clothes dryers, water heaters and and other high-power 240 volt appliances cannot be run on a transformer from a 120 volt circuit. They must be powered from a separate branch circuit that has the right size breakers, cable and socket outlet to suit the appliance.
Why 250 ohm resistance using for transmitter calibration?
In this situation, to calibrate a transmitter you need a power circuit and communicator circuit. The Hart communicator used in the calibration process is connected to the power source circuit in parallel. The power source circuit is the one that has ammeter, 250 Ohm resistor, and power source all connected in series. As the transmitter sends output mA, it creates volt drop across the 250 Ohm resister. Let's say the volt drop across the resistor was 1 Volt. Now, back to the Hart communicator. It is a load, meaning there will be a volt drop across the Hart communicator. Since it is in parallel with the power circuit, it is also parallel with the resistor. So, the 1 volt drop across the 250 Ohm resistor will also make 1 volt drop across the Hart communicator. Technically speaking, the 1 volt drop across the Hart communicator is only true if its resistor is also 250 Ohm. However, it does NOT matter what voltage drop is in the Hart communcator. It only sees the "relative" voltage drop changes to measure the changes in transmitter outputs.
Can you connect a 220 volt stove to a 120 volt circuit?
Yes, this is a safe connection. A range is usually wire rated at 40 amps and the manufactures do not make a 40 amp rated receptacle. The code requires the next highest rated receptacle be used which is a 50 amp rating. This is why the range receptacle is rated at 50 amps. This receptacle is known as a 3 pole 4 wire grounding receptacle, 14-50R 125/250 volt. Black wire to terminal X, red wire to terminal Y, white wire to terminal W and ground wire to terminal G.
What size wire need for 70 amp at 250 ft?
#3 copper.
What size wire for 250 v AC?
Wire size is not dependent on voltage - it is dependent on current. Please restate your question and provide the expected branch current.
