Note that the following measurements are used for copper cables. But what if you’re finding wires for other amperages?įor easier viewing, I’ve created a chart detailing the corresponding amperage capacity of different American Wire Gauge cables.

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.Īs we have previously mentioned, a 60-amp wire size can range from 6 AWG to 4 AWG. Meanwhile, a 6 AWG copper wire can only hold up to 55 amps before it falters. In particular, a 4 AWG copper cable can hold at least 70 amps of electricity before giving up. This is because 4 AWG can hold more amperage compared to 6 AWG. They reason that this 60 amp sub panel wire size is the gold standard for 60 amp subpanels. However, some electricians hold the opinion that only 4 AWG wires should be installed for 60 amp breaker panels. Therefore, the wire size for 60 amp 220v, for example, is still 6 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. Wire Size for 60 Ampere Breakerįor 60 ampere breakers, electricians and professionals suggest using a wire size gauge ranging from 6 AWG to 4 AWG. 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.Īnd if a wire is unequipped to handle certain amperage, then it may accidentally melt and even burn - resulting in a fire disaster which could ultimately burn your home down.įor this specific reason, we must be carefully aware of the appropriate size wires and their capacity to carry amperage load.Īs a rule of thumb, thicker and larger wire sizes are more capable of handling higher amperage loads, as they can mitigate the excessive heat produced by the electricity going through the cable. Size wires are important in breakers particularly because of one reason: safety. Why Size Wire is Important for Breakers.
