A tamper proof control system includes a housing, and a cap. The housing includes a housing body defining an interior volume to accommodate an electronic process control device and further includes a first end having a housing threaded portion. The cap includes a cap body that defines an interior volume and further includes a proximal end, a cap threaded portion, an exterior surface, and at least one groove formed on the exterior surface. The proximal end of the cap body defines a coupling portion. Upon threadably securing the cap to the housing, the coupling portion of the cap engages the housing threaded portion to restrict relative rotation between the housing and the cap.

Tamper proof approaches for securing an enclosure

A terminal box including a housing having a base, a side wall extending from the base, and a first opening opposite the base to provide access to wiring terminals to be mounted adjacent an inner surface of the side wall. The terminal box further includes a second opening in the side wall, the second opening providing access to a curved wiring guide within the housing. The curved wiring guide is shaped to guide electrical wires away from the base and toward a central portion of the first opening.
