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

ALL of the equipement in the room is either cord and plug connected or hard wired, right?

Unless the electrician that connected the equipement or wired the room forgot to connect the ground wires, all of the equipement is already bonded.

The code requires all services to be connected to the same grounding electrodes, hence the separate systems has no relevance.

Hope this helps!
Dave
