This is in a non-accessible area at the rear of a 19" rack-mount power supply. Only service or maintenance people can access. Also, the knock out cannot be pushed inward on the chassis, only outward when the top cover is removed.

In other words is it mounted outside of an enclosure? A few days ago it was brought to my attention that any outlet box with knockouts cannot be used in accessible areas. This includes the OUTSIDE of a wall where conduit is routed. These knockout boxes are designed with the assumption that they will be inside a wall or other enclosure.

Can anyone direct me to specific requirements on how much or how little force is required to remove these knock outs? Is a tool required or not if it only pushes outward? thanks, -doug ================================= Douglas E.
