Breaker Tripping

[paulspond]

I currently have the following run cycles from 1pm-5pm and 1am-5am. What I have noticed is the 1am-5am run cycle trips the breaker when the outside temp is in above 85 during the day. The 1pm-5pm works fine every time. When the temp is below 85 I have no issues with any of the run cycles.

Current pump is hayward ii super dump
Pump location is in basement pool room

Any idea what could be causing this.

Thanks in advance for any advice

There are 2 options, something is happening that is causing the breaker to trip when it should, or the breaker may be getting old and weak and tripping at a lighter load than it should. I would suggest replacing the breaker and seeing if the problem goes away.
