Grounding

[rpb]

Im currently instaling a 1200amp 3-phase 120/240 volt service and cannot get 2 of the same opions on how to ground and bond this situation.Here's what i have,1200 amp disconect connected to 8 125amp meter stacks where the ground and neutral are isolated from each other,then onto a splice box,from there to a ct cabinet and finally nippled in to our 400amp subpanel.Now the problem is in the meter stacks they have 3phases and a neutral bar W/ no EG for the CT & Sub-panel. Whats the best way to install this thanks.

Re: Grounding

The section of your switchgear that contains the 1200 amp main disconnect is grounded, connecting the grounded conductor, the equipment grounding conductor, the grounding electrode and the main bonding jumper. All of the switches downstream of the 1200 amp disconnect have the grounded conductor (neutral) and the equipment grounding conductor separated.
