TOTOSOJU The chassis of a Champ Car as described here weighs approximately 1,110 pounds (500 kg). One incredibly interesting characteristic of the chassis is the fact that the engine and transmission are actually a part of the chassis -- they are known as stressed members. These versions of the 5-15R or 5-20R receptacle are residual-current devices, and have "Test" and "Reset" buttons (and sometimes an indicator light which may be normally on or normally off per the vendor's design).|How does all of this Come Together?
