[Ref: NEC, Table 310-16]
Notes:
1. AWG= American Wire Gauge.For a complete listing on allowable Ampacity of conductors,
consult NEC, Table 310-16.
2. For Aluminum wires, see NEC, Table 310-16.
3. See NEC, Table 310-16 for footnotes that modify the information in the table.
4. ROMEX (Nonmetallic Sheathed Cable) should be sized to 60�C column of NEC, Table
310-16.
5. Service Conductors are sized for wire types listed in NEC , Table 310-16, footnote #3,
for 120/240, 3-wire, 1-phase Dwelling Service & Feeders.
6. Note: At present time, U.L. lists Circuit Breakers (CB's) and equipment rated at 100
amps or less based on the use of conductors sized to the 60�C rating in the NEC. For
Circuit Breakers and equipment rated over 100 amps are based on the use of conductors
sized to the 75�C rating in the NEC.
7. Higher temp. rated conductors may be used, but the size of the conductors must be
determined on the basis of the 60�C Ampacity on circuits 100 amps or less. NEC 110-14(c).
8. Conductors Type: See NEC, Table 310-13.
9. For conductors identification, see NEC 300-12.
