I have a Lenox A/C, about 12 years old. - when the a/c compressor
running it trips the 30 amp circuit breaker when it recycles. It
starts from a cold start ok, but after it has been running a while, it
will trip the breaker. Any suggestions. - I know I'll have to call
a technician but I would like to have a idea of what it could be.

thanks
