Question – 200 Amp Main Circuit Breaker Tripping – Part 3


By Dave Rongey - Summary:

My 200 amp main electrical circuit breaker trips. Should I replace it?

Dave that ICM relay I believe is a single circuit time delay relay, I have two separate A/C compressors on two separate thermostats. In order to make them not fire at the same time I would need to put a time delay relay between the units so they never fire at the same time. I don’t believe this TDR will do the job. Is there something I’m missing??

I understand your concern, I thought about this as well. I know a way to use an actual Time Delay Relay – not the one I mentioned before. The problem with the time delay mentioned before is that it does not have sets of contacts where the other a/c unit control circuit can be wired through it.

Having said this however, I really would ask you to call a local HVAC Contractor and run your request through them and see what they come up with. It’s very possible they have a method, then please let me know the details so I can update my info.

If you do not have any luck with a local HVAC Contractor then the next method simply involves a 24VAC Time Delay Relay and Socket Base with contacts that will allow you to absolutely do the job. Allen Bradley Cat # 700-HT12BA24 or equivalent with socket base.
