I need to run new 200 A service cables from a residential outside disconnect to the main panel in the garage. I would like to use individual conductors in conduit. What size grounding conductor should I use? Table 250-66 says #4 minimum. However, commercially available 2/0 Cu SER utilizes a #1 bare copper conductor. If #4 is OK whay is the #1 conductor used in the SER???
