Abstract

A conductor guide member for a circuit breaker terminal assembly includes a body having at least one conductor guide surface configured and disposed to facilitate alignment between at least one terminal connection member of the terminal assembly and at least one conductor. The at least one conductor guide surface gradually slopes from a first end to a second end. The second end defines a recess.

First claim

What is claimed is:

1. A conductor guide member for a circuit breaker terminal assembly comprising:
a body having at least one conductor guide surface configured and disposed to facilitate alignment between at least one terminal connection member of the terminal assembly and at least one conductor, wherein the at least one conductor guide surface gradually slopes from a first end to a second end, the second end defining a recess; wherein the conductor guide member includes a fastener receiving portion formed in the curvilinear conductor guide surface.

2. The conductor guide member according to claim 1 , wherein the fastener receiving portion is provided in the recess of the at least one conductor guide surface.

3. The conductor guide member according to claim 1 , further comprising: a mechanical fastener element captured in the fastener receiving portion, the mechanical fastener element being configured and disposed to engage with a threaded portion of a mechanical fastener.

4. The conductor guide member according to claim 1 , wherein the conductor guide member includes one or more mounting members extending substantially perpendicularly relative to the at least one conductor guide surface.

5. The conductor guide member according to claim 1 , wherein the body defines a portion of a lower terminal assembly for the circuit breaker.

6. The conductor guide member according to claim 5 , wherein the circuit breaker comprises an industrial circuit breaker having a voltage rating of up to about 1000 volts and a current rating of up to about 6400 amperes.

7. The conductor guide member according to claim 1 , wherein the at least one conductor guide surface comprises a substantially curvilinear guiding surface.

8. A method of connecting, a conductor to a circuit breaker terminal assembly, the method comprising:
passing an end of the conductor along at least one conductor guide surface;
positioning a connection element provided on the end of the conductor adjacent a connection member provided on a terminal of the circuit breaker; and
aligning the connection element with the connection member;
inserting a mechanical fastener through a connection member provided on a lower terminal of the circuit breaker and the connection element into a fastener receiving portion formed in the at least one angular conductor guide surface.
