The ampacity of number 8 aluminum wire can vary based on factors like insulation type and ambient temperature, but it typically ranges from about 30 to 40 amps for general use. For a 200-foot run, voltage drop should also be considered, as longer distances can reduce efficiency. It's advisable to use voltage drop calculations to ensure the wire can handle the intended current without excessive loss. Always consult local electrical codes and standards for specific applications.
A 1/0 aluminum conductor will limit the voltage drop to 3% or less when supplying 30 amps for 500 feet on a 240 volt system.
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.
A #6 aluminum conductor will limit the voltage drop to 3% or less when supplying 20 amps for 200 feet on a 240 volt system.
A 3/0 aluminum conductor will limit the voltage drop to3% or less when supplying 125 amps for 175 feet on a 220 volt system. If the 125 amp load is a sub distribution panel that is not going to be fully loaded to 125 amps then using the exact connected load, which might be smaller than 125 amps will effect the wire sizing. The grounding conductor for that size distribution panel is #6 bare copper.
A 1/0 AWG aluminium conductor will limit the voltage drop to 3% or less when supplying 60 amps for 330 feet on a 240 volt system. The cable will be rated as ACWU 90. ACWU 90 cables are primarily intended for exposed and concealed wiring in dry or wet locations and where exposed to the weather. For use in ventilated, non-ventilated, and ladder type cable trays in wet and dry locations; direct earth burial; service entrance above or below ground.

150 amps
Without a given unit, you can not make that number through a feet stick. You need to include a unit in order to indicate the number on the stick.
A 400 MCM copper conductor will limit the voltage drop to 3% or less when supplying 100 amps for 700 feet on a 240 volt system. This size will allow the conductor to be loaded to 80 amps. 100 x 80% = 80 amps. Conductors are only allowed to be loaded to 80% or their rated capacity. If you need the full 100 amps then you would need to use a wire with a rating of 125 amps. 125 x 80% = 100 amps. A 600 MCM copper conductor will limit the voltage drop to 3% or less when supplying 125 amps for 700 feet on a 240 volt system.
To carry 20 amps over a distance of 100 feet, you typically need to use at least 10-gauge wire for copper or 8-gauge wire for aluminum. This accounts for voltage drop and ensures safe operation. Always consider local codes and regulations, and consult a professional electrician if unsure.
30 amps is how much a 10-2 wire will carry at 110 feet. 10 gauge wire is only good for thirty amps per the national electrical code. Using 80% of the breakers usage you will actually be getting only 24 amps.
Yes, body heat can be lost through the feet due to the large number of blood vessels in the feet that can release heat into the environment. Wearing socks and appropriate footwear can help to minimize heat loss through the feet.
This is a voltage drop question. A voltage at 30 amps needs to be stated to answer the question.
