Easy startup for A.C.
I was recently scrolling you tube for info on A.C. easy starts and came across easy startup plug in version. It was pretty interesting that it is a plug in at the post and is blue tooth so you can ...

EZ Starts are very easy to install.
This plug in unit looks like it might be a power factor correction device Those are good too but I'm not sure they would qualify as an Easy Start.
A "true" easy start/soft start simply limits the inrush current required to charge the starting capacitor. This can be done with a current limiting resistor or by modifying the shape of the wave (shrink/chop).
People are hung up on the fact that the Easy Start is mounted directly to the starting capacitor and A/C motor windings. IT DOES NOT MATTER WHERE IS MOUNTED ! It just needs to detect that there is a sudden spike in current above a certain amount and then limit that current ! (This "spike" is so short and so fast that a typical fuse or circuit breaker can not respond.)
I remember "ELI the ICE man" ! My concentration was on digital circuits so I did not retain much about power electrical. I know industrial locations get a surcharge from the PoCo it there power factor is out of whack. I always thought power factor correction was a 3 phase "thing".
