Abstract

A communications and processing module is provided. The communications and processing module is electrically coupleable to a circuit breaker to provide the circuit breaker with additional capabilities. The communications and processing module includes a housing, at least one electrical contact positioned in the housing, an output lug positioned in the housing, wherein an electrical path is defined between the at least one electrical contact and the output lug, at least one sensor positioned in the housing and operable to sense at least one operating condition of the circuit breaker, and at least one communications interface positioned in the housing and communicatively coupled to the at least one sensor, the communications interface operable to receive data from the at least one sensor that is indicative of the at least one sensed operating condition to facilitate exporting the received data to a remote computing device.

First claim

What is claimed is:

1. A kit comprising:
a communications and processing module electrically coupleable to a first circuit breaker to provide the first circuit breaker with additional capabilities, the communications and processing module comprising:
a housing;
at least one electrical contact positioned in said housing and electrically coupleable to a load lug of the first circuit breaker;
an output lug positioned in said housing and electrically coupleable to a current carrying line, wherein an electrical path is defined between said at least one electrical contact and said output lug;
at least one sensor positioned in said housing and operable to sense at least one operating condition of the first circuit breaker; and
at least one communications interface positioned in said housing and communicatively coupled to said at least one sensor, said communications interface operable to receive data from said at least one sensor that is indicative of the at least one sensed operating condition to facilitate exporting the received data to a remote computing device; and

an adapter that is physically and electrically coupleable between the communications and processing module and a second circuit breaker sized differently than the first circuit breaker to allow the communications and processing module to provide the second circuit breaker with the additional capabilities.

2. The kit of claim 1 , wherein said at least one electrical contact comprises one of a conductive spring and a conductive pin adapted to directly contact the load lug of the first circuit breaker.

3. The kit of claim 1 , wherein the adapter includes (i) a first electrical contact that has a similar shape to the load lug of the first circuit breaker and is electrically coupleable to the at least one electrical contact of the communications and processing module and (ii) a second electrical contact that is electrically coupleable to a load lug of the second circuit breaker.

4. The kit of claim 3 , wherein a first side of the adapter that includes the first electrical contact has a different profile than a second side of the adapter that includes the second electrical contact.

5. The kit of claim 4 , wherein the second side of the adapter has a larger profile than the first side of the adapter.

6. The kit of claim 1 , wherein said housing comprises a plurality of tabs, said plurality of tabs adapted to engage corresponding slots in a mounting rail to physically couple said communications and processing module to the mounting rail.

7. The kit of claim 1 , wherein said housing comprises at least one engagement feature adapted to physically couple said communications and processing module to an adjacent communications and processing module.

8. The kit of claim 7 , wherein said at least one engagement feature comprises a post adapted to engage a corresponding aperture formed on the adjacent communications and processing module.

9. The kit of claim 7 , wherein said at least one engagement feature comprises a rail adapted to engage a corresponding slot formed on the adjacent communications and processing module.

10. The kit of claim 1 , wherein the communications and processing module further comprises a display operable to dynamically display information associated with the at least one sensed operating condition.

11. The kit of claim 1 , wherein said communications interface comprises at least one of a memory card interface, a wired communications interface, and a wireless communications interface.

12. An electrical distribution center comprising:
a circuit breaker comprising a load lug;
an adapter comprising (i) a first interface coupled to the circuit breaker and (ii) a second interface having a different profile than the first interface; and
a communications and processing module coupled to the second interface of the adapter, said communications and processing module comprising:
a housing;
at least one electrical contact positioned in said housing and electrically coupled to said load lug of said circuit breaker via the adapter;
an output lug positioned in said housing, wherein an electrical path is defined between said at least one electrical contact and said output lug;
at least one sensor positioned in said housing and operable to sense at least one operating condition of said circuit breaker; and
at least one communications interface positioned in said housing; and

communicatively coupled to said at least one sensor, said at least one communications interface operable to receive data from said at least one sensor that is indicative of the at least one sensed operating condition to facilitate exporting the received data to a remote computing device.

13. The electrical distribution center of claim 12 , further comprising a mounting rail defining a plurality of slots, wherein said housing of said communications and processing module comprises a plurality of tabs, said plurality of tabs engaging corresponding slots of the plurality of slots to physically couple said communications and processing module to said mounting rail.

14. The electrical distribution center of claim 12 , wherein said housing of said communications and processing module comprises at least one engagement feature configured to physically couple said communications and processing module to an additional communications and processing module.

15. The electrical distribution center of claim 14 , wherein said at least one engagement feature comprises a post configured to engage a corresponding aperture formed on said additional communications and processing module.

16. The electrical distribution center of claim 14 , wherein said at least one engagement feature comprises a rail configured to engage a corresponding slot formed on said additional communications and processing module.

17. The electrical distribution center of claim 12 , further comprising:
at least one conductive wire electrically coupled to said circuit breaker, said at least one conductive wire configured to distribute power to said circuit breaker from an electrical power source; and
a communications and processing hub, said communications and processing hub comprising a current transformer operable to measure a current flowing through said at least one conductive wire.

18. The electrical distribution center of claim 12 , wherein said communications interface comprises at least one of a memory card interface, a wired communications interface, and a wireless communications interface.

19. A method comprising:
electrically coupling an adapter to a load lug of a first circuit breaker;
electrically coupling a communications and processing module to the adapter such that the communications and processing module is electrically coupled to the first circuit breaker via the adapter, wherein the communications and processing module is not capable of directly coupling to the load lug of the first circuit breaker;
sensing, using the communications and processing module, at least one operating condition of the first circuit breaker; and
transmitting data indicative of the at least one sensed operating condition from the communications and processing module to a remote computing device.

20. The method of claim 19 , further comprising:
decoupling the communications and processing module from the adapter; and
electrically coupling the communications and processing module directly to a load lug of a second circuit breaker without the adapter.
