AC unit triping breaker
Have not seen anything on this topic, my system is a 3ton, build is 1994, now the unit is tripping the C/B at the service panel. The C/B is a 40amp and the wiring from the service panel to the outside disconnect is 10/2, the amp pull on start up is is 25.7 just above the minimum. My main question is with a 40amp circuit should the wiring from the service panel be 8/2?? OH BTW, the wire sometimes gets warm and the distance from panel to outside is 20ft or so.
Thanks in advance!!
