Imo something's wrong .
What is the model number of your a/c?
Totally not true.
Mine can draw 25 amps to start with the mods in place when the line voltage is low. Today while I was working on it (the camper), the line voltage was 115 volts.
It is only for 5 seconds or so, but easily seen on my AC amp display.
Running amps is about 14.9 amps (compressor and fan).
To be UL Listed, the start up amps can not be more than 1.56 times the rated Load amps.
The compressor needs 11.9 volts @ 115 Volts (start up voltage 11.9 * 1.56 or 18.56 amps JUST for the the compressor. Then (without the fan mod) you have to add the start up amps for the fan (3.4 running * 1.56 = 5.3 amps).
That is 23.86 amps @ 115 volts. As the voltage drops due to extension cords, area usage, brown outs, that start up amperage can spike right up there above 30 amps for a properly operating air conditioner.
