Are there any prohibitions to putting a 240V electric range receptacle with a switch behind the range to lock out front-control ranges from young children?
Have seen this more than once in nursing or limited care facilities for ranges or cooktops in accessible areas. Best one was a Square D molded case switch (60A) which comes in an enclosure that is padlockable.
Nursing home we did two years ago had a definite purpose contactor in the attic. 120v control was switched with a wall mounted key switch in the kitchen area.
