Both CSA and UL state that enclosure doors that provide access to live parts that can cause electric shock must require the use of a tool or key of some sort to open or remove the door.
I would like to know if there are interpretations of this requirement that are different from the basic, "Put a lock on every cabinet door that you supply." (at least with live parts inside) How else can one read this requirement?
