[From NEC 2012 310.15(B)(16)] For a 350 MCM copper wire with: an insulation factor of 75 and 90 degrees C; not more than 3 current-carrying conductors in Raceway, Cable, or Earth; and based upon ambient temperature of 30°C ; has an amperage rating of 310 and 350 amps respectively.
As a rule of thumb, you could consider their rating to be double with two sets paralleled together for 620 or 700 respectively. Be sure to account for temperature derating [NEC 2012 310.15(B)(2)(a)].

For a 600 amp parallel run, it is recommended to use at least 500 kcmil copper or 900 kcmil aluminum wire for each set of parallel conductors to ensure proper current-carrying capacity and voltage drop considerations. It's crucial to consult local electrical codes and standards to determine the exact wire size requirements for your specific installation. Professional advice from a licensed electrician is also recommended to ensure safety and compliance.

What size wire would you use for a 70KW 240 vac single phase generator?
For a 70kW 240V single phase generator, you would typically use a wire size of 3/0 AWG copper wire. This size wire is rated to handle the current carrying capacity required for a generator of that size to ensure safe and efficient operation. Be sure to consult with a professional electrician to confirm the correct wire size for your specific installation.
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.
Can you run two 60 amp sources in parallel to get 100 amps out?
No, you cannot run two 60 amp sources in parallel to get 100 amps out because each source will still provide a maximum of 60 amps. When you connect them in parallel, the total current output will remain the same as the output of a single source, which is 60 amps in this case.
What wire size should you use for 600 amps?
For 600 amps, you would typically need at least a 250 MCM wire size to safely handle the current without overheating. It's recommended to consult with a professional electrician to determine the specific wire size needed based on the application and local electrical codes.
Which wire used single phase 240v 6.5kw load?
I = W/E. Amps = Watts/Volts = 6500/240 = 27 amps. A #10 copper conductor with an insulation factor of 90 degrees C is rated at 30 amps. If the load is continuous the conductor can only be loaded to 80% of its capacity. 30 x 80% = 24 amps which is too low for your load. Move to the next size wire which is a #8 which is rated at 40 amps x 80% = 32 amps. As long as no long distance runs are involved this wire size will work well.
What size wire for 400 amp distribution panel?
For a distribution panel rated at 400 amps parallel runs of 3/0 conductors will do the job.

What size wire do you need for 15 amps?
AWG 10.
Can you run two 60 amp sources in parallel to get 100 amps out?
No, you cannot run two 60 amp sources in parallel to get 100 amps out because each source will still provide a maximum of 60 amps. When you connect them in parallel, the total current output will remain the same as the output of a single source, which is 60 amps in this case.
What is amp size for 14 wire?
15 amps.
What size wire for 250 amps?
15mm approx.
What size of wire is needed for 1500 amps?
There is no single conductor that will handle 1500 amps. For ease of handling, the conductors should be installed in parallel, triple or quad runs. For a parallel run, 2 - 2000 MCM with an insulation factor of 90 degrees C will give you a total ampacity of 1550 amps. For a triple run, 3 - 750 MCM with an insulation factor of 90 degrees C will give you a total ampacity of 1500 amps. For a quad run, 4 - 500 with an insulation factor of 90 degrees C will give you a total ampacity of 1580 amps.
What size of copper do you need for a 1250 amps rating?
There are different combination to obtain a current capacity of 1250 amps. A parallel run of #1250 MCM wires. A triple run of #600 MCM wire. The most flexible run would be with a quad run of #350 MCM wire.
What wire size is good for 100 amps?
# 4 copper wire short distance.
What wire size is needed for 1800 amp service?
There is no one wire that is rated for 1800 amps. The service will have to be a quad parallel of the conductors. A 600 MCM conductor with an insulation factor of 90 degrees C is rated at 475 amps. This conductor paralleled into four equal lengths will give an ampacity of 1900 amps for each leg of the service.
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.
