Title: John David Stephenson: Innovator in Circuit Breaker Technology

Introduction

John David Stephenson is a notable inventor based in Roswell, GA (US). He has made significant contributions to the field of circuit breaker technology, holding a total of 4 patents. His innovative designs have improved the functionality and safety of electrical systems.

Latest Patents

One of his latest patents is the "Multi-pole handle lock for circuit breakers." This invention features a base plate and a movable locking plate assembly designed to mount onto at least two circuit breakers. The handle restrictor plate allows each handle to independently move to the tripped position while maintaining the circuit breaker handles in the same position as each other. This design enables the restricted circuit breakers to operate as a logical group, and the low profile of the plates allows for visual inspection of the handle ends to determine their tie status.

Another significant patent is the "Self-adjusting plug-in line terminal." This line terminal for a circuit breaker includes a body forming two opposing legs and a third leg. The opposing legs create a passage for receiving a stab from a panel board. Each of the opposing legs has a convex surface facing the passageway, which helps maintain alignment of the stab. A fixed contact is attached to the third leg, connecting to a moveable contact of a circuit breaker, while an arc runner partially encloses the perimeter of the fixed contact.
