I’m trying to verify the grounding conductor size I need to jump the water meter. The primaries are URD #2 AL 15 kv. Secondary’s are 3 sets 500kcmil run in parallel. 3 phase service. If I’m reading 250.66 correctly I am to use 3/0 to go from ground ring in vault to basement water meter. My question is, am I reading this correctly?
