    Is there an electrical control box behind the cabinet behind the stairs

    In every home, there is a box under the stairs, in a cupboard, maybe even in the garage that contains all the switches and safety devices that control and operate the electrical system in your home. The presence of a live electrical box hidden behind a permanent structure creates a serious fire risk. The fundamental mandate driving all. While not specifically excluded by the National Electrical Code (NEC), there are two code standards that a panel must comply with to be located under a stair: 1) The under-stair space is usally a closet, and a panel cannot be located in a closet near ignitable material [NEC 240. So, if. Would putting an electrical junction box in this area be a violation of electrical code? If I put it there I would mark in the cabinet above it that there is a junction box below so that it would be easy to identify and find. I'm thinking of adding under stairs drawers, but I need access to the fuse box and meters which are right in the middle of the wall. Help your fellow Redditors crack the electrical code.
