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 will carry 52 amps - the service is 8 feet away?
A #6 copper wire with an insulation factor of 75 or 90 degree C is rated at 65 amps.
What size wire needed for 25 amps 220 volts for 75 feet?
10 AWG in copper.

What size feeder wire for 100 amps?
Service wire for 100 amps requires AWG #3 copper.
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 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?
Number 10 thnn copper wire.
What is amp size for 14 wire?
15 amps.
What size wire for 250 amps?
15mm approx.
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
