Ground Wire Size For 60 Amp
Ground wire size for 60 amp circuits is fast with WireGaugeCalc, since you pick the overcurrent rating and the tool returns the equipment grounding conductor.
It reads the values straight from NEC 250.122 so the copper or aluminum ground matches the breaker protecting the circuit.
You get the right gauge before you pull wire, so the install passes inspection.

How The 60 Amp Equipment Ground Is Sized
The equipment grounding conductor is sized by the breaker rating, not the load, so a 60 amp breaker sets the minimum ground.
NEC 250.122 lists 10 AWG copper or 8 AWG aluminum as the typical equipment ground for a 60 amp circuit.
What Sets The Ground Conductor For A 60 Amp Breaker
A few inputs decide the equipment grounding conductor:
- Overcurrent device rating, which is 60 amps here
- Conductor material, since aluminum runs one size larger than copper
- 10 AWG copper as the common 60 amp ground
- 8 AWG aluminum where aluminum is used
- Upsizing the ground if the ungrounded conductors are upsized for voltage drop
One app for every NEC calculation
WireGaugeCalc keeps the calculations you reach for most in one place:
- Voltage drop and wire sizing for any run
- Conduit fill for EMT, PVC, and RMC
- Box fill and junction box sizing
- Ampacity and temperature derating
- Motor circuit and load calculations
- Conduit bend offsets and saddles
Built for the field, works offline
The whole app runs on your phone, so it keeps working in a basement, an attic, or a job site with no signal.
There is no account to create and nothing to load. Open it, run the number, and get back to work.
- No signup and no signal needed
- Answers in a tap, not a spreadsheet
- Same tool on phone, tablet, and desktop
Every result cites the NEC article
Each answer shows the table or formula it came from, so you can check the method and learn the code as you go.
That makes the app useful on the job and during exam prep, since the reasoning is right next to the number.
Switch the code year your job runs on
Jurisdictions adopt the NEC at different times, so you can match the calculation to the code in force:
- NEC 2017, 2020, and 2023 tables
- Copper and aluminum conductors
- 60, 75, and 90 degree C terminations
- Single-phase and three-phase systems
Run the number, then get back to work

What size ground is needed for a 60 amp breaker?
Per NEC 250.122 a 60 amp circuit uses a 10 AWG copper or 8 AWG aluminum equipment grounding conductor. Confirm the size against the current NEC and your local authority having jurisdiction before wiring.
Does the ground get bigger if I upsize the circuit conductors?
Yes, since NEC 250.122(B) requires the equipment ground to be increased in proportion when the ungrounded conductors are upsized for voltage drop.
Is WireGaugeCalc free to use?
Yes. Every calculator is free to run with no signup. A paid tier adds saved projects, PDF reports, and extra code years, but the core math stays free.
Does it work without internet?
Yes. The app runs on your device, so it keeps working with no signal on a job site, in a basement, or in an attic.
Are the results code accurate?
Results follow published NEC tables and standard formulas, and each answer shows the article it came from. It is a field aid, not a stamp of approval, so verify against the current code and your local authority before you wire anything.
Which NEC code year does it use?
You can switch between NEC 2017, 2020, and 2023, since jurisdictions adopt the code at different times. Pick the year your job runs on.
