An electrical plug provides protection against electrical surges with a replaceable surge protector cartridge that is readily removable and replaceable along an exterior of the plug. Surge protector circuitry in the cartridge can absorb an electrical surge received at the plug from an electrical mains source, and the electrical plug can maintain electrical continuity from plug prongs to an electrical cord both before and after the surge protector has absorbed an electrical surge.

Housing for electrical junction

An electrical power unit or electronic data unit includes an outer housing, a circuit board positioned inside the outer housing, a frame inserted inside the outer housing, and a face plate fitted over the outer housing. The circuit board supports, for example, a high voltage AC electrical receptacle, a low voltage DC electrical receptacle, and a switch, each of which is electrically connected to the circuit board. The frame defines a plurality of outlet openings for receiving respective one of the AC electrical receptacle, the DC electrical receptacle, and the switch. The face plate defines outer receptacle openings that align with respective outlet openings of the frame to provide access to the respective AC electrical receptacle, DC electrical receptacle, and switch.
