According to the 2008 NEC Code Book a #4 AWG Copper wire is rated at 95 Amps @ 90C (194 F), 85 Amps @ 75C (167 F), and 70 Amps @ 60C (140 F). These allowable amperage ratings are based on the wires type of insullation.
70 amps.
A 4 mm diameter copper wire with an insulation factor of 75 or 90 degrees C is rated at 65 amps.
A #12 wire is rated at 20 amps, continuous loading at 80% = 16 amps. # 10 wire is rated at 30 amps, continuous loading at 80% = 24 amps.
Yes you can. You did not say how many amps were required.
250 amps maximum.
70 amps.
# 4 copper wire short distance.
The amps that a four gauge wire will handle will depend with the thickness of the wire. If the wire is thin, the four gauge will handle 95 amps.
Aluminum 4/0 wire car carry 180 amps at at 75 degrees Fahrenheit or 205 amps at 90 degrees. .
A 4 mm diameter copper wire with an insulation factor of 75 or 90 degrees C is rated at 65 amps.
80 amps
A #12 wire is rated at 20 amps, continuous loading at 80% = 16 amps. # 10 wire is rated at 30 amps, continuous loading at 80% = 24 amps.
Yes you can. You did not say how many amps were required.
Yes, # 4 AWG copper and 100 amps is the max.
250 amps maximum.
A 4 mm diameter copper wire with an insulation factor of 75 or 90 degrees C is rated at 65 amps.
4000000VA/69000 = 57.97 amps, say a #6 wire. #4 to be safe.
