Hello frnds,
What is the exact meaning of Chasis? What is the difference between Chasis and Ground(Common or Return)? Can I refer Chasis as the Body Ground?
Expecting your positive and electrally correct reply!
Thanks Regards, YUVRAJ Service & Development Engineer
Chassis usually means the metal structure that holds the electronic devices. In the days of vacuum tubes it was the metal plate on which the tube sockets were mounted. Today it can be any mechanical structure that holds the components
The chassis is often grounded (earth ground) for safety purposes if it possible for the user to come in contact with it. It may be used as a zero volt referance ground for the electronics. Whether the chassis is grounded and how it used is dependant on the application and the local safety requirements.
I have never heard of the term "body ground" being used for anything.

Maybe he was thinking of Frame Ground ( US usage ) aka FG.
Frame ( USA ) = chassis ( UK )
