If you're installing a 60-amp subpanel, however, it's best to connect it to the main panel with 4-gauge wire. What size wire do I need for a 70 amp sub panel?
Why Size Wire is Important for Breakers
Size wires are important in breakers particularly because of one reason: safety. To further explain, the total size of the wire critically determines whether the equipped conductors of a wire can handle the amperage that will flow through it.
Wire Size for 60 Ampere Breaker
For 60 ampere breakers, electricians and professionals suggest using a wire size gauge ranging from 6 AWG to 4 AWG. All household wires have a rating of at least 600V, so only amperage really matters when it comes to determining wire gauge. Therefore, the wire size for 60 amp 220v, for example, is still 6 to 4 AWG.
Determining Proper Size Wire
Now that we’ve cleared that up, it’s for us to further our knowledge regarding wires by knowing how to determine the appropriate wire sizes for specific connections.
Conclusion
Knowing what size wire for a 60 amp breaker is truly a headache for homeowners with no prior knowledge of handling electrical maintenance. However, don’t fret! This guide was specifically curated for your perusal in determining the proper size wirings for breaker sub panel maintenance.
