Ground
The electrical reference or protective connection used by a system.
IN ONE SENTENCE
Ground can mean protective earth, signal reference or chassis connection, and those are not always the same thing.
In normal English
Industrial systems distinguish protective earth from DC 0 V and signal grounds. Incorrect bonding can create noise, faults or safety problems.
Why would I use it?
