Good design practices limit wire ampacity due to over current to 80% of rated ampacity under most circumstances.

The wire size will not be able to handle this load and it will cause catastrophic failures.

Good design requirements should limit overall voltage drop to less than 5%.

Notes:

¹Ampacity based NEC Table 310-16, which is based on three (3) current carrying conductors at 30 degrees Celsius Ambient

²Calculations based on 0.85 Power Factor

³Based on NEC Table 9

⁴Check Conductor derating Factors for more than three (3) current carrying conductors

⁵Load for Voltage Drop is calculated based on 80% ampacity load of maximum allowable ampacity
