hi all, I'm about tackle a project and could use some advice. in my facility, we have multiple transformers that I will be grounding to one Grounding Electrode Conductor in an old 5 story building. In reading the NEC and the handbook, I have a pretty good idea of how I will be going about the install. (except the taps) the code offers 3 options. is there a listed connector you could suggest using? there is limited space in the riser closet, but that is where it will be tapped. I would like room for easy expansion in the future..(i.e., more transformers), so is the best option for me to use a listed connection to some type of busbar? if you've done this type of installation before, please offer any tips or links. thanks.
