What size wire for 60 amps?

2 Different 60 amp wires

The No. 4 AWG is best for 60 amps. This is the best size wire for 60 amps and 50 amps. However, with a 60 amp wire, you can go up to using a 6 gauge wire. Use THHN or RHW type insulation.

What Is the Correct 60-Amp Breaker Wire Size?

Use a 4 AWG wire for a 60 amp breaker. Wire gauge is very important. Resistance will trigger the wire to get too hot when the optimum current level for which the breaker is ranked passes through it if you try to use wire that's too small of amperage. If that happens, a fire might be started and you really do not want that to happen. On the other hand, a heavy-gauge wire is tough to deal with, hard to link/connect and have a high cost. Be sure not to use too much of an oversized wire.

What size wire should I use for a 60 amp subpanel?

You can get away with 6 AWG when you have a short run of wire, however, due to voltage drop, if you ever decide you want to go more than 100 feet then a 4 AWG is the size you should choose.

What is ampacity?

Ampacity is defined as the total amount of current that a cable or wire can carry safely.


Gauge Amperage
14-gauge wire 15 amps
12-gauge wire 20 amps
10-gauge wire 30 amps
8-gauge wire 40 amps
6-gauge wire 55 amps

Using wrong wire size for your breaker.

There are so many different things that can happen when you use the wrong wire size for your breaker. If you use a wire size that is too big for your 60 amp breaker, not much will happen except having to pay a high price for said wire. On the other hand, if you use too much of a small wire for your 60 amp breaker, then there are so many things that can go wrong.


Knowing what gauge wire is right for your next project is crucial. Hopefully you have done the necessary research before taking on any type of DIY or hired a professional. Above i went over all you need to know about using 60 amps.
