Abstract: A housing assembly for a pair of side-by-side watt-hour meter sockets. The housing assembly includes a rectangular housing having back, side and end walls. A recessed opening is formed in the back wall to receive a standard panel board chassis. An insulated panel closes the recessed opening in the rear wall. A horizontal partition divides the housing into meter socket and switch compartments. A pair of individually removable cover panels are positioned side-by-side to close the front of the meter compartment. An opening is provided in each cover panel to expose a meter to view. An inwardly-extending partition of electrically insulating material is attached to the side of each cover panel which is adjacent to the other cover panel. The partition terminates short of the insulated panel, closing the rear recessed opening of the rectangular housing to protect its meter socket against accidental contact when the other cover panel is removed from the rectangular housing.

Abstract: A tamper prevention housing assembly for mounting on a standard panelboard chassis, enclosing at least one watt-hour meter and its overload-protected switch arranged in a secure sequence between the bus bars of the panelboard chassis and the output terminal lugs of the switch. A first security partition divides the housing into a meter compartment and a switch compartment; the partition has an opening formed that is closed by a security panel fastened from the meter compartment side. A first set of bus connectors electrically connect the bus bars to the meter socket; a second set of connectors electrically connect the meter socket to the switch, through the opening in the security partition. A removable, lockable panel closes the front of the meter compartment, whereas a separate lockable door covers the front of the switch compartment.
