com 9 Branch Circuit Fuse Size, Individual Motor Load, With Starter Overload Relays:(NEC 430. NEC 240-3 The rating of the fuse or circuit breaker generally determines the minimum size of the circuit conductor, per the following table: Minimum Wire Size Fuse or Circuit Breaker Size Copper / Aluminum 15 amp14 n/a. See full list on achrnews.

For overhead spans up to 50 feet, the minimum conductor size for outside branch circuits is 10 AWG. For longer spans, it's 8 AWG [225.6 (A)]. When these spans are installed over a building, they must be securely supported by substantial structures [225.15]. Where practicable, supports must be independent of the building [230.29].
