ERIES GEOTHERMAL R-410A STAGED CAPACITY GENERAL INFORMATION
Maximum size of the time delay fuse or circuit breaker for protection of field wiring conductors.
These “Minimum Circuit Ampacity” values are to be used for sizing the field power conductors. 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.
