60 Amp Breaker Wire Size. A 60 amp panel controlling several circuits could easily draw a maximum of 60 amps before the subpanel breaker trips. 4 8 60 0 08 ohms.
Breaker size wire size based on copper thhn wire increase one size when using aluminum. 6 copper is good for 65 amps since you cannot buy a 65 amp breaker normally people use a 60 or a 50 amp breaker. 4 copper is a good deal more expensive and will handle 100amps.
For 60 amp electrical service 6 gauge copper or aluminum wire is the correct size to power such devices as electric furnaces and large electric heaters.
When the amperage increases the width of the wire needs to be larger to conduct more electricity. The corresponding size for 60 amp is a wire gauge size 4 however there are certain important assumptions that that rule of thumb relies on we will expand on those in the rest of this article. When the amperage increases the width of the wire needs to be larger to conduct more electricity. 4 copper is a good deal more expensive and will handle 100amps.
