I will be putting #2 cu thhn (Ampacity @ 75c is 115a) on a 100a breaker and use a #8 cu egc. A thought though crossed my mind, when upsizing conductors to improve vd one must also upsize the egc, vd is not a concern in this case, I'm only using #2 instead of #3 because that's what I have already. So, should I go up on the egc in this scenario?
