Example combinations:

Recommended Wire Size

  • Recommended: 8 AWG copper wire – supports 30A MCA and 35A max fuse
  • One Size Smaller (10 AWG): May run hot under load and is not code-compliant at this amperage—avoid use
  • One Size Larger (6 AWG): Best for long runs—minimizes voltage drop and increases safety margin

Note: These units are pre-charged with R-454B and are not compatible with earlier R-410A systems. Always confirm your air handler configuration before purchase. Specifications subject to change.
