I am trying to determine what would be the minimum accessible area that should be available to access junction boxes. A standard single gang entry is about 6 square inches.
New LED light access plates provide and 1.5 inch square hole cover plate that fits on a standard 4 square. They then recommend to cover the box with 3/16 mud so that only the 1.5" square hole is accessible.
Are there any standards, seems to me to get splices, wire nuts or repairs done might end up violating the Definition under article 100.
