How the NEC 2017,705.12(B)(2)(3)(C) doesnot violate the NEC 2017,705.12(B)(2)(3)(b).
The Situation Looks like:
6 Tesla battery connected to 400 ampere load center. 6 Tesla battery has each 30 ampere breaker.. at the end the 400 ampere load center is fed by 200 A breaker in the center fed panel.. According to 705.12(B)(2)(3)(C) is this code complaint?
The Center fed panel has only the 200 ampere breaker for that 400 ampere Load center. each Tesla requires 30A OF OCPD
if we follow 2017,705.12(B)(2)(3)(b)
6*30=180A Backfeed, is connected to 400A Load center ,
but the main panel only has 1.2*200-200=40A Backfeed ( which is straight no)
can somebody explain me how it works
