Minimum size main over current protection device in the MDP for 838.5Amps of load. I get 1000 amp OCP? Am i correct? I got this because you go up to the next standard size or not required to go up? It is asking minimum. If I go up then my conductors have to be equal to or over this breaker size. My service entrance conductor options are 2 sets 500kcmil, 2 sets of 400kcmil, and 3 sets 300kcmil. The three sets of 300kcmil is the only set that would put me up over 800amps at 855amps. Either the question is screwed up or it is ok to round down you main OCP size? Please help
