ABSTRACT:
A tamper-resistant electrical meter housing includes an unbreakable cover assembly that cooperates with a matable base to enclose a meter device supportable on the base. The cover assembly includes an annular ring secured to the cover. A locking leaf spring is coupled to the cover assembly. The leaf spring is aligned to slide along the top of a rim portion of the base and snap into a recess to lock the cover assembly against rotation and removal. Once the cover assembly is locked to the base, the leaf spring is substantially concealed from view, so that an unauthorized person cannot effect removal of the cover to obtain access to the meter. The base also includes a specific area in alignment with the recess, which area is identifiable only by an authorized person. A hole may be drilled in this area by an authorized person and a tool may then be inserted through this hole to effect disengagement of the leaf spring and removal of the cover assembly from the base.
