Hello

I have an equipment room with multiple power sources fed from seperate utility transformers. I have to bond a lot of gear in the room and my question is where should I get my ground? Building steel?

The room has many communications/server cabinets in it and I want them all bonded to ground. I know how I'm going to get to the ground once I find it but I want to make sure I select the proper path to earth.

Thanks in advance
