Aluminum 4/0 wire car carry 180 amps at at 75 degrees Fahrenheit or 205 amps at 90 degrees. .
For a 100 Amp breaker panel it would be 2 AWG. For 150 Amps it would require 2/0 (2 ought) aluminum wire.
If you mean 2/0 copper wire it is rated 175 amps. # 2 wire is 115 amps. If you are referring to 2.0 metric it is rated 15 amps.
10 amps
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.
70 amps.
Aluminum 4/0 wire car carry 180 amps at at 75 degrees Fahrenheit or 205 amps at 90 degrees. .
You are probably thinking about 1/0 wire (1 ought wire). In copper it is rated at 175 amps and in aluminum 125 amps.
10-2 Amps
For a 100 Amp breaker panel it would be 2 AWG. For 150 Amps it would require 2/0 (2 ought) aluminum wire.
It uses 2 amps
150 amps
If you mean 2/0 copper wire it is rated 175 amps. # 2 wire is 115 amps. If you are referring to 2.0 metric it is rated 15 amps.
2 amps mili means 1,000
about 3 or 4
200 amps on a single phase service. Incoming cable should be 4/0 Aluminum or 3/0 copper. Aluminum is OK for entrance cable, as it is stranded and is made of an alloy that does not have "creep" like the single strand aluminum wire of the 70s had.
A 2000 MCM aluminum conductor with an insulation factor of 90 degrees C is rated at 650 amps. Parallel 500 MCM aluminum conductors with an insulation factor of 90 degrees C have the capacity of 2 x 330 = 660 amps. Triple 250 MCM aluminum conductors with an insulation factor of 90 degrees C have the capacity of 3 x 215 = 645 amps.
