Job calls for separate bonding conductor because the customer does not want to use the tray as an EGC (24in tray w/ 2 sq.in. cross-section (2000amp). Running separate 3/0 copper or better to bond (3) 1200amp mains to a transformer. They exit the transformer through EMT chase nipples, enter the tray, then enter the 1200amp main enclosures with roughly 2ft EMT nipples. If I understand correctly, I need to bond this cable tray to the EMT on both ends with 3/0 copper or better.
My question is: What is the proper way to bond the tray to EMT? Bonding bushing like rigid?
