How many amps can you run through 200 feet of number 8 aluminum wire?

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.
