60 Amp Breaker Wire Size
A common 60 amp planning lookup is 6 AWG copper or 4 AWG aluminum, but the actual conductor depends on the wiring method and terminals.

Acknowledge the limitations before relying on this as a planning lookup.
Electrical sizing depends on the adopted NEC edition, terminal temperature ratings, insulation type, conductor material, conduit fill, derating, grounding, equipment labels, and local inspection requirements.

How this calculator works
Select conductor material and run length for a cautious 60 amp planning lookup.
Lookup scope
The engine maps a 60 amp rating to common residential copper and aluminum planning rows.
Length flag
Runs over 100 feet are flagged for voltage-drop review.
Electrical safety
This is not electrical design advice and does not replace the adopted NEC, equipment labels, or inspection requirements.

- Lookup scope: Limited common branch-circuit or feeder lookup; confirm conductor type and terminal ratings.
- Not checked: Voltage drop, grounding conductor size, neutral load, service load calculation, conduit fill, ambient temperature correction, bundling, and equipment-specific requirements.

4 AWG aluminumCommon 60 amp conductorFAQ
Is 6 AWG always enough for 60 amps?
No. Ampacity depends on conductor type, terminal ratings, temperature, conduit fill, bundling, and local rules.
Does this size the ground wire?
No. Grounding conductor sizing is separate.
Does distance change wire size?
Long runs may need larger conductors for voltage drop even when ampacity is adequate.
