Will awg 10 wire carry 30 amps for 30feet?
Yes, a #10 wire will carry 30 amps for 30 feet. If the load is rated as continuous then the wire will have to be derated to 80% capacity which will leave you with 24 workable amps. If the load demands currents higher that 24 amps then you will have to go to the next wire size up which is a #8 which is rated at 45 amps.
What size wire do you need for 15 amps?
AWG 10.
What size aluminum wire for 100 amps undergroundservice 60 feet from meter?
A 3/0 aluminum conductor will limit the voltage drop to 3% or less when supplying 150 amps for 150 feet on a 240 volt system. This size will allow the conductor to be loaded to 120 amps. 150 x 80% = 120 Conductors are only allowed to be loaded to 80% or their rated capacity. If you need the full 150 amps then you would need to use a wire with a rating of 190 amps. 190 x 80% = 152 amps A 4/0 aluminum conductor will limit the voltage drop to 3% or less when supplying 190 amps for 150 feet on a 240 volt system.
What wire size is good for 100 amps?
# 4 copper wire short distance.
How do you solve for the size of wire when the given is kva?
The V stands for volts and A is amps. If for example you have a 12kVA device and are running off a voltage of 120 volts then Amps = 12000/120 = 100. You then use the calculated amps in a wire size table to get the correct size.
What size wire will carry 55 amps 75 feet?
AWG # 6 copper
What size wire needed for 25 amps 220 volts for 75 feet?
For a 25 amp load at 220 volts over a distance of 75 feet, you will need a 10-gauge wire to ensure safe and efficient electrical conductivity. This wire size allows for minimal voltage drop and meets the necessary ampacity requirements for the circuit. Make sure to consult local electrical codes and regulations before installation.
Will awg 10 wire carry 30 amps for 30feet?
Yes, a #10 wire will carry 30 amps for 30 feet. If the load is rated as continuous then the wire will have to be derated to 80% capacity which will leave you with 24 workable amps. If the load demands currents higher that 24 amps then you will have to go to the next wire size up which is a #8 which is rated at 45 amps.
What size wire do you need to run to an air conditioner that has a maximum breaker size of 40 amps and a minimum circuit size of 25.3 amps?
You would need to use a wire size that is rated for at least 40 amps to be safe and to meet the requirements of the air conditioner. A common wire size for this application would be 8 AWG copper wire, which is rated for 40 amps.
What size wire do you need for 15 amps?
AWG 10.
Will 12-2 wire pull 20 amps?
12-2 (#12-2 conductor) wire doesn't "pull" 20 amps. However, it's ampacity rating is that of 20 amps. #12 copper wire is rated for a total load of 20 amps. So, always use a 20 amp breaker with it.
What size wire and breaker do you need for a 5000 watt garage heater?
Look on the heater and see what amps it is pulling. That will determine the wire size and breaker size. It must be on a dedicated circuit. 15 amps = AWG # 14 wire with 15 amp breaker 20 amps = AWG # 12 wire with 20 amp breaker 30 amps = AWG # 10 wire with 30 amp breaker 40 amps = AWG # 8 wire with 40 amp breaker
What size wire do you need to carry nineteen amps for two hundred feet at two hundred forty volts ac?
10 guage
What is amp size for 14 wire?
15 amps.
What size wire for 250 amps?
15mm approx.

What is the wire size for 50 feet distance 120 volts 12 amps?
For a 50 feet distance with 120 volts and 12 amps, you should use a 14-gauge wire to ensure electrical safety and efficiency. A 14-gauge wire is rated to handle up to 15 amps for household wiring applications.
