They used 2 gauge stranded copper wire. I believe it's 1/2 inch thick.
As far as the voltage and amperage from the strike, you are correct. First it's very short and Triangle installed 4 ground wires one at each corner of the house. Three are required by code. The whole grounding system is all connected so the charge would run down all 4 ground wires. In addition, the system is then bonded to the utility ground where there is an additional 5th ground rod that came with the house.
