The distance you can run 8/2 underground wire 500' depends on factors like amperage and acceptable voltage drop. For example, with a 40-amp load on a 120-volt circuit and a 3% voltage drop, 8-gauge copper wire is typically good for up to 50 feet. If your load is less or you’re running 240 volts, you can cover greater distances with your 8/2 direct burial wire, 500 foot spool. Always consult a voltage drop calculator or a licensed electrician for precise installation guidance.
