Had a service call last week...A/C split tripping breaker.
Suction head pressure OK,
SH & SC OK,
Air flow OK,
Amperage draw OK,
Megger readings OK,
Customer NOT playing with T stat OK,

2 days later compressor blew...
relace whole unit under warranty, compressor not available

1 day later breaker keeps tripping

installed a time delay before the contactor and set for 5 minutes...

everything now works great..

this is an FYI posting.., hope it helps

Short cycling? Make and model of thermostat?

[smokin68]

sounds like the problem is still there.....the time delay just prevents the short cycle.

Weak breaker or loose wires.

Did you pull the panel cover to check for a good conection ? Or hot breaker ?

Just my 2 cents.

Who manufactured the equipment?

I'd have to agree with smokin68--sounds like problem is still there. I've seen a few units that trip because of a loose wire at the breaker.

You said time delay "fixed" the problem. My guess is that your problem still there. Are you shure system is not short cycling?
