Shockless plug and socket assembly for safe interconnection of live circuits

1. A system, comprising:

a receptacle socket including:

a first prong receptacle for a ground circuit,

a second prong receptacle for a neutral circuit, and

a third prong receptacle for an active voltage circuit;

a plug housing including:

a first prong contact corresponding to the first prong receptacle for the ground circuit,

a second prong contact corresponding to the second prong receptacle for the neutral circuit, and

a fourth prong receptacle for the active voltage circuit; and

a jumper component including:

a third prong contact corresponding to the third prong receptacle for the active voltage circuit, and

a fourth prong contact corresponding to the fourth prong receptacle for the active voltage circuit, wherein the fourth prong contact is completely recessed within the jumper component.

2. The system of claim 1 , wherein when the first and second prong contacts of the plug housing are inserted into the first and second prong receptacles of the receptacle socket, respectively, connections for the ground and neutral circuits are connected without connecting any connections for the active voltage circuit.

3. The system of claim 2 , wherein when the third and fourth prong contacts of the jumper component are inserted into the third prong receptacle of the receptacle socket and the fourth prong receptacle of the plug housing, respectively, connections for the active voltage circuit are connected.

4. The system of claim 1 , wherein the receptacle socket further includes at least one guide bar, and wherein the plug housing further includes at least one guide slot corresponding to the at least one guide bar of the receptacle socket for ensuring that only the first and second prong contacts of the plug housing can be inserted into the first and second prong receptacles of the receptacle socket, respectively.

5. The system of claim 1 , wherein the receptacle socket further includes at least one screw hole, and wherein the plug housing further includes at least one captive screw corresponding to the at least one screw hole of the receptacle socket for securing the plug housing to the receptacle socket.

6. The system of claim 5 wherein the placement of the at least one screw hole and the at least one captive screw is asymmetrical to ensure that the plug housing cannot be secured to the receptacle socket upside down.

7. The system of claim 5 , wherein the at least one captive screw is of sufficient length to prevent the insertion of the fourth prong contact of the jumper component into the fourth prong receptacle of the plug housing until the plug housing is fully secured to the receptacle socket.

8. The system of claim 1 , wherein the plug housing further includes at least one access hole to allow electrical wiring to enter the plug housing for electrical connection to the first and second prong contacts and the fourth prong receptacle.

9. The system of claim 1 , wherein the jumper component further includes overcurrent protection circuitry.

10. The system of claim 9 , wherein the overcurrent protection circuitry includes a fuse.

11. The system of claim 9 , wherein the overcurrent protection circuitry includes a circuit breaker.

12. The system of claim 1 , wherein the receptacle socket and the plug housing further include corresponding contacts for a data transfer connection.

13. The system of claim 1 , wherein the receptacle socket is mounted in an electric meter collar.

14. The system of claim 13 , wherein the plug housing and jumper component are used to connect a distributed energy system to the electric meter collar.
