These "Minimum Circuit Ampacity" values are to be used for sizing the field power conductors. Refer to the National Electrical code (latest
version), Article 310 for power conductor sizing. CAUTION: When more than one field power 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 (3) current carrying conductors are in a raceway.
Maximum size of the time delay fuse or circuit breaker for protection of field wiring conductors.
Based on 75°copper wire. All wiring must conform to the National Electrical Code and all local codes.
NOTE: The Maximum Overcurrent Protection (MOCP) value listed is the maximum value as per UL 1995 calculations for MOCP (branch-
circuit conductor sizes in this chart are based on this MOCP). The actual factory-installed overcurrent protective device (circuit
breaker) in this model may be lower than the maximum UL 1995 allowable MOCP value, but still above the UL 1995 minimum
calculated value or Minimum Circuit Ampacity (MCA) listed.
IMPORTANT: While this electrical data is presented as a guide, it is important to electrically connect properly sized fuses and conductor
wires in accordance with the National Electrical Code and all local codes.
