AC 20amp breaker trips mid day
Just came from Vegas 103 deg with no AC problems. At our new location which is also about 103 deg, the ac compressor would cycle and the fan would stay on with the thermostat on auto. Now it trips th...

“107 volts is getting very low. Low voltage causes an AC unit to draw more current. Anything below 105 volts can result in damage to the AC unit over time. Not what you want to hear, but you should probably stop running it. An autoformer would cure that problem.”
Usually YES, but it’s possible to cite ‘a few’ outlier scenarios where an autoformer might be just a paperweight - consider the low a available potential when operating near the upper limits of a 30a pedestal’s amperage...In this case, I simply reduce my power demands (e.g. shutting off converter charger, etc) to allow the autoformer necessary headroom to function properly... An autoformer is not a substitute for poor power management, and with only 30a to work with.....
I also have a Soft-Start installed (as an alternative to a properly sized and functioning capacitor), but in ‘my case’ have found the autoformer a better solution...I would note too that (try as I might), I find it somewhat odd that the manufacturer will not divulge what makes it work...In search of a solution, this admittedly didn’t keep me from trying it though...
