When selecting the ampacity of conductors fora single motor, the rules set in 430.22 apply. If after you multiply thefull-load current in the motor tables and the product comes out to a value thathas an asterisk next to the conductor?s size in Table 310.16 [Double asteriskin the 2011?s Table 310.15(B)(16)], does the small conductor rules apply? Example:Assuming all terminations are rated for 75?C - Can a 115-volt single phase ?horsepower motor be wired with 14 AWG, or does it need to have 12 AWGconductors to be code compliant?
