a second terminal structured to electrically connect to a load;
separable contacts electrically connected between the first terminal and the second terminal and being moveable between a closed position and an open position;
an operating mechanism structured to trip open the separable contacts;
an electronic trip unit structured to detect a fault condition based on power flowing between the first and second terminals and to retrieve diagnostic or setting information associated with the circuit interrupter; and
a wireless unit structured to provide the setting or diagnostic information associated with the circuit interrupter to an external device via a wireless communication protocol, and
wherein the wireless unit is structured to generate a web server and host a web page on the web server; and wherein the wireless unit is structured to provide the setting or diagnostic information associated with the circuit interrupter to the web page.

2. The circuit interrupter of claim 1 , wherein the wireless unit is structured to receive setting information from the external device via the wireless communication protocol; and wherein the wireless unit is structured to communicate with the electronic trip unit to adjust settings of the circuit interrupter based on the setting information received from the external device.

3. The circuit interrupter of claim 1 , wherein the diagnostic information includes real time diagnostic information associated with the circuit interrupter; and wherein the wireless unit is structured to continuously provide the real time diagnostic information associated with the circuit interrupter to the external device.

4. The circuit interrupter of claim 1 , wherein the wireless unit is structured to receive setting information from the external device via the web page; and wherein the wireless unit is structured to communicate with the electronic trip unit to adjust setting of the circuit interrupter based on the setting information received from the external device.

5. The circuit interrupter of claim 1 , wherein the web page is accessible to the external device via a web browser.

6. The circuit interrupter of claim 1 , wherein the setting information associated with the circuit interrupter include at least one of full load ampere setting, long delay time, short delay pickup and short delay time.

7. The circuit interrupter of claim 1 , wherein the diagnostic information associated with the circuit interrupter includes at least one of current information, voltage information, a number of trips, a last reason for tripping and a manufacturing date.

8. The circuit interrupter of claim 1 , wherein the wireless communication protocol is selected from wi-fi, Bluetooth and Zigbee.

9. The circuit interrupter of claim 1 , wherein the wireless unit is structured to communicate with the external device via a direct wireless connection to the external device.

10. The circuit interrupter of claim 1 , wherein the wireless unit is structured to communicate with the external device via a network.

11. The circuit interrupter of claim 10 , wherein the wireless unit is structured to communicate with the network via a first connection; wherein the network is structured to communicate with the external device via a second connection; and
wherein the first connection is a wireless connection and the second connection is a wireless or wired connection.

12. The circuit interrupter of claim 1 , wherein the electronic trip unit and the wireless unit are integrated into a single component.

13. The circuit interrupter of claim 1 , wherein the electronic trip unit and the wireless unit are separate components that are electrically connected with each other.

14. A method for communicating circuit interrupter information, the method comprising:
establishing communication with an external device via a wireless communication protocol;
retrieving setting or diagnostic information associated with the circuit interrupter;
providing the setting or diagnostic information to the external device via the wireless communication protocol;
generating a web server;
hosting a web page with the web server; and
providing the setting or diagnostic information to the web page.

15. The method of claim 14 , further comprising:
receiving settings information from the external device via the wireless communication protocol; and
adjusting setting associated with the circuit interrupter based on the received settings information.

16. The method of claim 14 , further comprising:
receiving settings information from the external device via the web page; and
adjusting settings associated with the circuit interrupter based on the received settings information.

17. The method of claim 14 , wherein the web page is accessible to the external device via a web browser.

18. A communication system comprising:
an external device; and
a circuit interrupter structured to communicate with the external device via a wireless communication protocol, the circuit interrupter including,
