Please look around your computer keyboard for your caps lock and turn it off. All upper case is hard to read.
Multiple grounding connections to major equipment is common as an added margin of safety and to lower the impedance to ground. This is what we often call a "belt and suspenders" approach. If one is good, two are better.
I have no idea what IEC requirements are, but making two ground connections will not hurt anything.

Thankyou

Whilst several standards give certain guidelines, national codes will dictate earth conductor sizes alongside with the system application. What Im trying to say is; It depends...
