The ampacity of a wire depends on factors like gauge, insulation, and installation. For 8/2 underground wire 500', which typically refers to 8 AWG copper wire with two conductors designed for direct burial, the ampacity is usually between 40 and 55 amps, depending on the insulation type and installation conditions. Always consult the National Electrical Code (NEC) or a similar authoritative source to determine the precise ampacity for your specific application, as factors such as ambient temperature and burial depth can affect safe current ratings. Proper installation ensures safety and compliance with electrical standards.
