My friend has purchased one of these new compressors that claim to have 4 HP. The compressor runs on 115V at 15A. All this data has been taken from the nameplate (The plug is 15A).
Imagine my surprise when I practically called him a liar and I said that you can't get much over two horsepower from 15 amps, and you're only allowed to load it to 80% which makes it even less...
What gives?
