100 amp sub panel ground wire size.

The 60A breaker feeding the 6/3 (I hope it's copper) will limit the current to the subpanel to 60A per 120v leg. The panel must be rated for a minimum of the size of the breaker feeding it. You can put as many breakers in the panel as the panel will hold, you just can't concurrently use loads that will exceed 60A per 120v leg.If the barn is less than 50' from the main panel, you could use #4 UF wire contained in conduit. If the run was closer to 150', the circuit would require #00 gauge wire, which is quite large. An electrician would place the wires in 2" or larger conduit to maintain the 50% threshold mentioned earlier.What Size Wire For 50 AMP Sub Panel? The amperage of the breaker will determine the wire size for a 50 amp sub panel. In most cases, you'll need to use a 6 gauge wire. For some sub-panels, you will need to use a 4 gauge wire.
