Hi guys

Looking to size my ground wire for an 800A service. According to the C.E.C. table-17 the ground wire size is based on the ampacity of the largest service conductor.

At the bottom of the table -17 it says for OVER 475 amps the size of the grounding conductor is -000- copper,How do I use this to size my ground for the 800 amp service or is this the size I use.

Thanks for the help guys
