Square D motor starter wire connections 

From time to time on the Garage Journal Discussion Forums, people will ask how to wire the motor starter used on larger air compressors. This is a short video, in the rough, showing how the starter is wired on my 7.5 hp two stage Husky air compressor. Brand doesn't really matter, all single phase 240v compressors that use a motor starter will wire the same way. Hope this helps someone.
