20 amp service question

I do it all the time.
I measured that my 15,000 btu AC takes 8 amps when running, so once I start it, I can add microwave or other appliances.
You have to check the appliances power. When big household microwave oven takes 1000 w and really need good 20 amp line, smaller microwaves will take only 400W.
Years ago I bought small RV combo - small coffee maker and toaster with top plate for eggs cooking.
I can run that combo on 800W generator that I bought as a backup for $80 at HF. Small microwave will run on 800w generator as well.

ANY 15k AC will NOT pull 8 amps. You either measured wrong or your amp tool was wrong. The MINIMUM amp draw of most AC Fan motors on HI is 2.8 to 3.1 amps. Then the compressor will be at least 11.0 to 13.9 amps. This is at 95 degree outside temp. So, you subtract 1 amp for each 10 degrees below 95.-----75 degrees outside temp that compressor if rated at 11 amps would pull 9 amps, but add the 3.0 fan amps and you still have 12 amps. There is no way a fully functioning 15K will pull less than 11 amps. Give me the brand and model number of your AC and I will give you exact figures. Doug
