Many of us have heard the old saying 'Its not the voltage that kills you, its the current!' In many cases, the same is true for your power tools and other high power equipment. While we cannot have the high power output of electrical equipment without high levels of current, we can now have it without the unnecessary and excessive levels of inrush current.
More current = More potential Heat. More Heat = More potential Damage.
It should be no surprise that adding an aftermarket soft starter, and reducing the damaging effects of inrush current (up to 50, 60, even 70 Amps), can add significantly to the working life of your power equipment.
