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.

For a 20 amp 250 volt circuit, you would typically use a 12-gauge wire. This wire size is rated to safely handle the current and voltage requirements of the circuit without overheating. It is important to always refer to local electrical codes and regulations to ensure compliance.

What size wire for 225 amp 208 volt 3 phase circuit y.?

For a 225 amp 208 volt 3 phase circuit, you would typically need to use a 3/0 AWG copper wire or a 250 kcmil aluminum wire. Be sure to consult with local electrical codes and regulations to ensure compliance with specific requirements for your installation.


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 circuit breaker to install for 10 amp 250 volt circuit?

For a 10 amp, 250 volt circuit, you should install a circuit breaker rated for at least 10 amps and 250 volts. A common option would be a single-pole, 10 amp circuit breaker designed for 240-250 volt applications. Be sure to check the specifications and compatibility with your specific electrical panel.


Can I run a 230 volt 20 amp table saw on 10 3 with a 250 foot run?

It is not recommended to run a 230 volt 20 amp table saw on a 10/3 wire with a 250-foot run. A longer wire run may result in voltage drop that could potentially damage the saw or cause it to operate inefficiently. It is advisable to consult with an electrician to determine the appropriate wire size for the distance involved.


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?

If the wire shorted out, it's possible that other components in the range could have been damaged as well, such as fuses, circuit boards, or heating elements. It's important to have a professional inspect the range to determine the extent of the damage and make the necessary repairs. Using the range without addressing the problem could be a safety hazard.

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 replace a 10 amp 125 volt extension cord with a 10 amp 250 volt extension cord?

Yes, you can replace a 10 amp 125 volt extension cord with a 10 amp 250 volt extension cord. The key specification to match is the amperage rating, which should be the same. The higher voltage rating of the replacement cord will allow it to be used with both 125 volt and 250 volt outlets safely.


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.
