Abstract

A wireless electrically isolated plug-n-play communications system for branch circuit breakers. The system providing means for automatically connecting the wireless electrically isolated communication system between the branch circuit breaker and a communications strip as the branch circuit breaker is being installed in the load center.

Claims

1. A bi-directional circuit breaker communication and control system comprising:

a load center enclosure;

a load center interior attached to a back surface of said load center enclosure and defining a plurality of branch circuit breaker stations, each said station providing means for mounting and electrically connecting at least one branch circuit breaker to an electrical distribution bus;

at least one communications strip lying immediately adjacent said back surface of said load center enclosure and having bi-directional wirelessly communications means for communicating with at least some of said plurality of branch circuit breakers having similar bi-directional wireless communications means as they are mounted in one of said branch circuit breaker stations.

2. The bi-directional circuit breaker communication and control system of claim 1, wherein said bi-directional communications means of said at least one communications strip includes a plurality of communications ports placed at a predetermined intervals such that each branch circuit breaker station is associated with one communications port of said at least one communications strip.

3. The bi-directional circuit breaker communication and control system of claim 2, wherein each said communications port includes an optical transceiver.

4. The bi-directional circuit breaker communication and control system of claim 2, wherein said optical transceiver is a LED transceiver.

5. The bi-directional circuit breaker communication and control system of claim 2, wherein said optical transceiver is an IrDA transceiver.

6. The bi-directional circuit breaker communication and control system of claim 2, wherein each said branch circuit breaker having bi-directional communications means includes a communications port configured to be in justaposed position with one of said communications ports of said communications strip when said branch circuit breaker is installed in a branch breaker station of said load center interior.

7. The bi-directional circuit breaker communication and control system of claim 1, wherein said at least one communications strip is connected to a controller.

8. The bi-directional circuit breaker communication and control system of claim 1, wherein each branch circuit breaker having similar bi-directional communications means and communicating with said communications strip communicates independently of all other branch circuit breakers communicating with said communications strip.

9. The bi-directional circuit breaker communication and control system of claim 1, wherein said at least one communications strip includes at least one microprocessor for processing data received from said branch circuit breakers having bi-directional communications means and/or for controlling said branch circuit breakers having bi-directional communications means.

10. The bi-directional circuit breaker communication and control system of claim 1, wherein said at least one communications strip is at least partially captured between said load center interior and said back surface of said load center enclosure.

11. The bi-directional circuit breaker communication and control system of claim 1, wherein said at least one communications strip is an integral part of said load center interior.

12. The bi-directional circuit breaker communication and control system of claim 2, wherein each said communications port includes a light pipe.

13. The bi-directional circuit breaker communication and control system of claim 2, wherein each said communications port includes a dust boot.

14. A method of communicating with and controlling a circuit breaker in a load center said method comprising the steps of:

placing at least one communications strip having a plurality of communications ports with wireless bi-directional communications means and at least one microprocessor for processing data and/or controlling branch circuit breakers adjacent a back surface of a load center enclosure;

attaching a load center interior to said back surface of a load center such that said at least one communications strip is at least partially captured between said load center interior and said back surface of said load center enclosure, said load center interior having a plurality of branch breaker stations each providing means for mounting and electrically connecting a branch circuit breaker to a line bus and being in register with one of said plurality of communications ports of said communications strip;

installing at least one branch circuit breaker having similar wireless bi-directional communications means in one of said branch circuit breaker stations of said load center interior, said wireless bi-directional communications means of said branch circuit breaker being configured to be in juxtaposed position with one of said communications ports of said communications strip such that bi-directional communications is established during installation of said branch circuit breaker into said branch circuit breaker station.
