Working on a job that has welded wire mesh instead of rebar in every concrete pad for switchgear and transformers, etc. The wire only has a diameter of .192" inches. It has to be bonded to the ground ring (4/0) and I'm trying to figure out what type of lug or crimp to use.

Having trouble finding something that matches that wire range. Any suggestion appreciated

I don't have a code book in front of me, but I thought concrete encased electrodes had to be of a certain size (3/8 or 1/2" maybe?) and have 20 linear feet within the concrete. Don't think you have to bond wire mesh.

I'm guessing this is a job spec. I agree with you it is not an NEC requirement.
