Question – 200 Amp Main Circuit Breaker Tripping – Part 2

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

Thanks for your quick response on this holiday weekend – you are correct, both AC units are running on 240V and by default are load balanced – its been a long week.

The LRA on the 4-ton unit is 105 and the LRA on the 2-ton unit is 55. The 4-ton unit’s compressor outside shows a min. fuse rating of 29A and a max of 50A – I was surprised to see that the 30A breaker that the 4-ton unit is on has never tripped. I thought I may have needed a new 200A main or maybe the terminals on it were loose. I guess if both units fire at the same time and my pool pump, well and other appliances are on at the same time I will have a potential problem.

As for the time delay relay, what manufacturer/rating would you recommend? I will also look at moving some of the higher 120V circuits, but the time delay relay sounds like a real fix- thank you!

Attached is the info on a relay that should work for you – I will be adding this to the web site soon as well, in fact here is a link to some new pages that explains relays – pay special attention to the time delay relay section. [Click here]
