Abstract

A load center includes an arc fault circuit interrupter comprising a plurality of contacts, an operating mechanism for separating the contacts, and an arc fault trip mechanism to generate a trip signal in the event of an arc fault detection. The load center also includes a neutral link electrically connected to the arc fault trip mechanism and the plurality of contacts. The load center further includes a mounting rail operatively coupled to the arc fault circuit interrupter, the arc fault circuit interrupter directly supported by the mounting rail. The load center yet further includes a neutral busbar and a plug-in neutral conductor electrically connecting the mounting rail to the neutral busbar.

First claim

What is claimed is:

1. A load center comprising:
an circuit interrupter having a plurality of contacts, an operating mechanism for separating the contacts, and an trip mechanism to generate a trip signal in the event of an electrical fault;
a neutral link electrically connected to the trip mechanism and the plurality of contacts;
a mounting rail operatively coupled to the circuit interrupter, the circuit interrupter directly supported by the top of the mounting rail;
a neutral busbar; and
a plug-in neutral conductor electrically connecting the mounting rail to the neutral busbar; wherein the plug-in neutral conductor comprises a first end and a second end coupled to the side of the mounting rail and the side of the neutral busbar, respectively, and wherein the neutral conductor is disposed between the circuit interruptor and the neutral busbar.

2. The load center of claim 1 , wherein the mounting rail provides a neutral conduction path for the circuit interrupter.

3. The load center of claim 1 , wherein the neutral link comprises an electrical wire.

4. The load center of claim 1 , wherein the neutral link, comprises a formed electrical conductor.

5. The load center of claim 1 , wherein at least one of the first end and the second end is removably coupled thereto the mounting rail and the neutral busbar, respectively.

6. The load center of claim 1 , wherein at least one of the first end and the second end is permanently coupled thereto the mounting rail and the neutral busbar, respectively.

7. The load center of claim 1 , wherein the respective couplings to the mounting rail and the neutral busbar, are formed with at least one of a bolted connection and a welded connection.

8. The load center of claim 1 , wherein the plug-in neutral conductor is snap-mounted to the mounting rail and snap-mounted to the neutral busbar.

9. The load center of claim 1 , wherein the plug-in neutral conductor terminating at one end with a snap-mounted coupling to the neutral busbar.
