This table indicates minimum conductor size for feeders
of the ampacity indicated where #/W indicates the #-Ampacity
and W-numbers of wire, #S/W indicates no ground.
All conductors shall be Copper unless noted otherwise.
* Conductor Ampacities shall be based on table 310.15(B)(16)
60 degree column up to 100 Amps and 75 degree column
above 100 Amps unless otherwise permitted by NEC. Ampacity
rating shall be selected in accordance NEC 110.14 (C).
The master electrician shall be responsible for ensuring
that no feeders or branch circuits are installed in a manner
or sized in such a way as to violate the NEC.

Ground Conductor based on #G where # is the ampacity from
the chart above, and the equipment ground chart indicates the
minimum equipment grounding conductor size #EG where
# is the rating/ setting of the overcurrent device protecting the
conductors and equipment.
Where discrepancies occur between the Feeder Schedule
Schedule and the Grounding Tables, the larger conductor
shall be used unless otherwise permitted by the NEC.
The installation shall meet all NEC 250 grounding and bonding
requirements including 250.4 Path for Fault Current. Provide
complete raceway systems metallically joined, connected, and
fittings as required for electrical continuity per NEC 300.10
