Abstract
A modular electrical component for electrical wiring systems is provided. The modular electrical component includes a removable electrical device, a base unit that fits within a junction box in the electrical wiring system and a mounting strap used to secure the base unit to the junction box. Typically, the removable electrical device has a plurality of power contacts that extend from a rear cover of the device, and the base unit has a plurality of terminal connections. The power contacts electrically connect to the terminal connections, when the replaceable electrical device is mated with the base unit. The removable electrical device may be, for example, a receptacle or switch. Preferably, the removable electrical device is a circuit interrupting device, such as a ground fault circuit interrupting device.
Claims15
A modular electrical component, comprising:
- a base unit having a plurality of first terminal members, and a plurality of second terminal members connectable to conductors in an electrical wiring system;
- a mounting strap secured to a rear cover of said base and capable of connecting said base to a junction box in the electrical wiring system;
- and
- a removable electrical device having a plurality of power contacts extending from a rear cover and capable of releasably connecting to said plurality of first terminal members, such that at least one of said plurality of contacts releasably connects to one of said plurality of said first terminal members,
- wherein said removable electrical device comprises a circuit interrupting device, and
- wherein said circuit interrupting device comprises:
- a housing;
- a line side conductive path disposed at least partially within said housing and connected to at least one of said plurality of power contacts;
- a load side conductive path disposed at least partially within said housing and connected to at least one of said plurality of power contacts;
- a circuit interrupting portion disposed at least partially within said housing and configured to break the continuity between said line side and load side conductive paths upon the occurrence of a predetermined condition;
- and
- a reset portion disposed at least partially within said housing and configured to make electrical continuity between said line side and said load side conductive paths.
A modular electrical component, comprising:
- a removable electrical device having a plurality of power contacts extending from a rear cover of said removable electrical device;
- a base unit configured to fit within a junction box of an electrical wiring system, said base unit having a plurality of terminal connections, wherein each terminal connection is connectable to at least one conductor in the electrical wiring system and to at least one of said power contacts;
- and
- a mounting strap secured to a rear cover of said base unit and capable of connecting said base unit to the junction box in the electrical wiring system,
- wherein said removable electrical device comprises a circuit interrupting device, and
- wherein said circuit interrupting device comprises:
- a housing;
- a first electrical conductive path disposed at least partially within said housing and connected to at least one of said plurality of power contacts;
- a second electrical conductive path disposed at least partially within said housing and connected to at least one of said plurality of power contacts;
- a circuit interrupting portion disposed at least partially within said housing and configured to break the continuity between said first and second conductive paths upon the occurrence of a predetermined condition;
- and
- a reset portion disposed at least partially within said housing and configured to make electrical continuity between the first and second conductive paths.
A modular electrical component, comprising:
- a removable electrical device having a plurality of power contacts extending from a rear cover of said removable electrical device;
- connecting means configured to fit within a junction box of an electrical wiring system for connecting said plurality of power contacts to at least one conductor in the electrical wiring system;
- and
- mounting means associated with said connecting means for mounting said connecting means to the junction box in the electrical wiring system,
- wherein said removable electrical device comprises a circuit interrupting device,
- wherein said circuit interrupting device comprises:
- a housing;
- means associated with said plurality of power contacts for conducting electricity between a line side and a load side of said circuit interrupting device;
- circuit interrupting means for breaking continuity between said line side and said load side of said circuit interrupting device upon the occurrence of a predetermined condition;
- and reset means for reestablishing electrical continuity between said line side and said load side of said circuit interrupting device;
- and
- further comprising reset lockout meant for preventing said reset means from reestablishing electrical continuity between said line side and said load side of said circuit interrupting device when said circuit interrupting portion is non-operational.
