Abstract

An angled plug-on neutral connector assembly of a circuit breaker. Angled plug-on neutral connector assembly includes a molded case including a bottom plane and a retaining portion, and a neutral connector received and constrained in the retaining portion, the neutral connector including a connector body including first and second prongs, and an opening between the prongs configured to receive a neutral bar. The opening is oriented in an angled orientation to the bottom plane, as defined by a connector angle measured between the bottom plane and a bisector line between the first and second prongs, wherein the connector angle is between about 30 degrees and about 70 degrees. Electronic circuit breakers including the angled plug-on neutral connector assembly, panel boards including angled neutral bars, and methods of making neutral connections between angled neutral bars and angled neutral connectors of circuit breakers are provided, as are other aspects.

First claim

What is claimed is:

1. A panel board, comprising:
a base pan of an insulating material, the base pan including a mounting plane configured to mount a circuit breaker;
a neutral bar coupled to the base pan, the neutral bar including a neutral axis, wherein the neutral axis is mounted to the base pan at an angled orientation defined by a bar angle measured between the mounting plane and the neutral axis, and wherein the bar angle is between about 30 degrees and about 70 degrees; and
a neutral assembly including a cross bar including an angled riser and wherein the neutral bar couples to the angled riser of the cross bar at one end thereof.

2. The panel board of claim 1 , wherein the bar angle is between about 50 degrees and about 70 degrees.

3. The panel board of claim 1 , wherein an end of the neutral bar is received in a pocket of the base pan.

4. The panel board of claim 1 , wherein the angled riser is received through an opening in the base pan.

5. The panel board of claim 1 , wherein the bar angle is between about 55 degrees and about 65 degrees.

6. The panel board of claim 1 , wherein the neutral assembly includes one or more neutral bus members which include multiple sockets and screws that are adapted to connect neutral wires of various circuits coupled to a circuit breaker.

7. The panel board of claim 1 , wherein a neutral terminal is provided on one side or both sides of the neutral assembly.

8. The panel board of claim 7 , wherein the neutral terminal is configured to receive a main neutral service line from a utility.

9. The panel board of claim 1 , further comprising:
a barrier member that functions to cover the cross bar below the base pan and function to insulate the neutral assembly from any enclosure that the panel board may be coupled to.

10. The panel board of claim 9 , wherein the barrier member is fastened to the base pan by snap features.
