60 amp breaker feeding two condensing units

This is not a DIY forum. IF we find none working items we may refer it out to the appropriate professional. You need a HVAC professional to remedy the problem.

Actually it’s an electrical problem. Based on the very wiring concept discussed in the original post. I’m an Electronic Technician by trade working mostly on low voltage equipment in hospitals. I was seeking insight by experienced people. Regardless of the nature an answer rather than a retort would have been reasonable. But thanks for being so helpful, your willingness to respond and the manner in which you do demonstrates a great deal of your knowledge.

Then a qualified electrician is who you need.

Point is, this is not a DIY forum. Good luck with your trouble shooting.
