I believe this has been covered before, however I can't seem to get the "search" feature to get very specific like it use to.
Lets say I have a 200A service on a single family dwelling. T310.15(B)(6) permits me to use 2/0 cu conductors for the service entrance and main power feeders. But lets say I use T310.16 instead and install 3/0 cu conductors. Does this represent an increase in the ungrounded conductor size and thus require an increase in the feeder EGC per 250.122(B)?
