I have a 2" run under the slab from one side of the home to the other to serve as a wireway for a 20kw generac and central AC compressors built on the same pedestal . As it stands 4#8s for ACs , 2#2s,1#6and a #8 and a #12 for generac. I will tap #6 generator neutral for service receptacle. Does this require derating since generator is only for emergency back up?
