I should install this so its always active. I get lazy and if I see good voltage on my surge guard then I don't put it on. I'm in a state park and using a 30 amp plug and its 100° out.
With both ac's running and being careful not to use any other 120v item we have been making out fine. Last night we started tripping the breaker. With the campground full for the weekend my volts went from 122v to 113v. I put the auto former on and it raised the volts to 123v and the tripping of the breaker stopped!! I have two extra plugs I installed, one of them I use for the battery charger, residential refrigerator and our upright freezer. The other plug is used for toaster, hair dryer, coffee pot etc. These two plugs are plugged into the 20 amp plug at the pedestal.
OK, to the point, I don't know if I have enough room to install the auto former. I just don't see enough room in there. Any ideas? I'm now convinced that it should be or I should use it religiously.
