OK, now let's dig a little deeper.....
1-1/4" raceway.....comm kitchen equip....28 current carrying conductors.....
45% derated, for 28ccc; ambient in comm kitchen?? site discussion for sure, or plan review reject/clarification........OH, I FORGOT, no permit, no inspection....
No paper trail??? DO NOT BET your life, or $1; you may be surprized how quick the client 'fesses' up who did the work. It's not really that hard for an AHJ, cop, insurance adjuster, etc., to get info.
That said, the chase nip debate cannot get a firm answer from me. More info needed.
