I have some specs to prep for a fiber install from the provider. It says: "Place new #6 ground wire bonded to an MGN." I'm not familiar with this acronym. Main Ground Neutral? Anyone know?
Multi Grounded Neutral maybe?
I also say multi grounded neutral based on the context.
In article 250 you will find part X. Grounding of Systems and Circuits of over 1 kV
And in that section the rules of MGN systems are discussed.
What is the voltage of the system you are working on?
If under 1,000 volts I imagine the person should have said the 'grounded conductor'
