Professional-grade wire sizing tool optimized for Southwire SIMpull® conductors and NEC technical standards.
Optimized calculations for Southwire's patented SIMpull® conductors, ensuring NEC compliance and installation efficiency.
Southwire's SIMpull® NM-B cable is color-coded for quick identification of the wire gauge. This industry standard helps prevent installation errors and ensures inspectors can verify gauge at a glance.
| AWG Size | Jacket Color |
|---|---|
| 14 AWG | White (15A) |
| 12 AWG | Yellow (20A) |
| 10 AWG | Orange (30A) |
| 8 AWG | Black (40-50A) |
Limits current to 100A and assumes 60°C termination ratings for maximum safety in home environments.
Allows for 75°C and 90°C ratings, common in industrial settings using Southwire THHN conductors.
Excessive voltage drop can indicate a run is too long, which also impacts the tension required to pull wire.
SIMpull® comes in reels, SIMpull CoilPAK™, and barrels for different job site scales.
Always cross-reference calculations with the latest Southwire Product Catalog for specific ampacity adjustments.
