Sorry if this should be in a different forum, I wasn't sure where to put it.

We're installing a new server rack in our office, and I unfortunately didn't realize until it arrived that the ground bonding kit is a separate purchase. The kit is essentially just a bunch of copper grounding straps to connect all the different rack components together (side panels, doors, etc) before then bonding the rack to the building's ground.

The kit seems rather pricey for what it is, and has a 3 week lead time.

I thought I could just make up the appropriate grounding straps myself, but am unsure of the type/thickness wire I would require. Our electrician will be in sometime in the next few days, but I'd like to get a head start if possible.

All components in the rack will be powered from two HP R3000 UPSs, which are each powered by a 16A wall socket (each on a separate circuit).

Thanks for the help.
