You say "closet". If equipment is located so that the person working on it must enter the "closet" they are not in line of sight of panel while working on it, either it will require a local disconnect or a perminantly installed lockable breaker device at the panel. If person is not required to "enter" the "closet" to perform maintenance functions, then you will be "in line of sight" at under 50ft.
