Based on 75° copper wire. All wiring must conform to the National Electrical Code and all

R

local codes.
These "Minimum Circuit Ampacity" values are to be used for sizing the field power conduc-

S

tors. Refer to the National Electric Code (latest revision), Article 310 for power conductor
sizing.

CAUTION: When more than one field power conductor circuit is run through one
conduit, the conductors must be derated. Pay special attention to note 8 of table 310
regarding Ampacity Adjustment Factors when more than three conductors are in a raceway.
