I couldn't figure why my dryer breaker kept popping about every 5 minutes. After putting 2 and 2 together I realized that it only happened when my central air was also running. I confirmed it by turning off the AC and the dryer ran through a complete 50 minute cycle. I have 200A service which I would think is enough.



Is there a logical reason for this? Is my breaker starting to fail?

is the central air on the same breaker that the dryer is?

No, they're each on their own pair of breakers - 2x25=AC and 2x30=dryer.

I would replace the 30 amp dryer breaker.

the central air breaker or dryer breaker may have bad connection to the busbar and overheat a little, so when both runs it triggers the dryer breaker, check if they become very hot to the touch while air and dryer are running for a long time

How close are the two breakers to each other?
