Shallow electrical protection device (GFCI, AFCI, and AFCI/GFCI) system and method
A device may include a housing including a face plate. A device may include a plurality of sensing cores each configured to receive a current flow through a center cavity, the current flow defining a current flow direction through the center cavity, wherein the current flow direction is parallel to the face plate.
1. An electrical outlet receptacle comprising:
a housing including a face plate; and
a solenoid having a central axis perpendicular to the face plate;
a plurality of sensing cores each configured to receive a current flow through a center cavity, the current flow defining a current flow direction through the center cavity,
wherein the current flow direction is parallel to the face plate; and
wherein the plurality of sensing cores are placed symmetrically in a translational direction across the electrical outlet receptacle.
2. The electrical outlet receptacle of claim 1 , further comprising:
a set of fixed contacts and a set of movable contacts;
a solenoid having a central axis perpendicular to the face plate, the solenoid having a first end and a second end opposite the first end;
a carriage movable axially along the solenoid and configured to interact with the set of movable contacts, the carriage configured to advance the set of movable contacts to form electrical communication with the set of fixed contacts during resetting of the electrical outlet receptacle;
a reset plunger with a portion extending through the first end of the solenoid and axially movable therein, the reset plunger being biased toward a rest position away from the carriage; and
an armature movable axially along the portion of the reset plunger extending through the solenoid, the armature being biased toward a rest position away from the carriage,
wherein the reset plunger includes an engaging portion and the carriage includes a latching portion, the engaging portion of the reset plunger being configured to connect to the latching portion of the carriage.
3. The electrical outlet receptacle of claim 2 , wherein the solenoid includes a coil bobbin with an inner coil and an outer coil.
4. The electrical outlet receptacle of claim 2 , wherein the reset plunger further includes a spring configured to bias the reset plunger toward the rest position.
5. The electrical outlet receptacle of claim 2 , wherein the armature interacts with the latching portion of the carriage when the solenoid is momentarily energized to cause engagement of the engaging portion to the latching portion in a latched state.
6. The electrical outlet receptacle of claim 5 , wherein in the latched state, the armature interacts with the latching portion of the carriage when the solenoid is momentarily energized to cause disengagement of the engaging portion from the latching portion in an unlatched state.
7. The electrical outlet receptacle of claim 5 , wherein pressing of the reset plunger causes the engaging portion to apply a downward force on the carriage at least until the electrical outlet receptacle is in the latched state, and subsequent release of the reset plunger causes the engaging portion to apply an upward force on the carriage to close the set of movable contacts and the set of fixed contacts.
8. The electrical outlet receptacle of claim 2 , further comprising at least one sensing core configured to receive a current flow through a center cavity, the current flow defining a current flow direction through the center cavity.
9. The electrical outlet receptacle of claim 8 , wherein the at least one sensing core includes a ground fault circuit interrupter (GFCI) core and an arc fault circuit interrupter (AFCI) core, the GFCI core having a first current flow direction and the AFCI core having a second current flow direction.
10. The electrical outlet receptacle of claim 9 , wherein the first current flow direction and the second current flow direction are identical to each other.
11. The electrical outlet receptacle of claim 9 , wherein the first current flow direction and the second current flow direction are substantially parallel to each other.
12. The electrical outlet receptacle of claim 9 , wherein the first current flow direction and the second current flow direction are at an oblique angle to each other.
13. The electrical outlet receptacle of claim 9 , wherein the first current flow direction and the second current flow direction are at a right angle to each other.
14. The electrical outlet receptacle of claim 9 , wherein the GFCI core and AFCI core are positioned in a symmetrical placement across a translational direction of the electrical outlet receptacle, the symmetrical placement allowing for no interference of the GFCI core and the AFCI core with contact terminals connectable to an external device.
