Arc Prevention Member Structure for Electrical Panel Sidewalls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical breaker panels lack effective mechanisms to prevent exposed wires from contacting the inner side walls, leading to potential electrical arcs or shorts, which can be dangerous and cause damage.
Innovation Solution
The electrical panel incorporates an arc prevention member with a body having an upper portion that couples to a longitudinal side wall and a lower portion that is arcuate in form, preventing exposed wires from contacting the inner side wall and thus inhibiting electrical arcs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wire insulation is removed for connecting to bus bar, then electrical connection is established, but exposed wire may contact inner side wall causing arc or short
Solution Approach 1:
The patent introduces an arc prevention member as an intermediary component between the exposed wire and the inner side wall of the breaker panel. This member includes a non-conductive body with a wire receiving portion that holds the exposed wire, and an arc prevention portion that extends toward the bus bar to prevent the wire from contacting the inner side wall, thereby eliminating the harmful electrical arc risk while maintaining reliable electrical connection
Solution Approach 2:
The arc prevention member is installed beforehand to create a protective barrier before any electrical arc can occur. The arc prevention portion is positioned to preemptively block the path between the exposed wire and the inner side wall, preventing the harmful effect before it can manifest

AI summary
An electrical panel having an arc prevention member wherein the arc prevention member inhibits exposed wire from contacting the inner surface of the sidewall of the panel box. The present invention includes a panel box having four side walls and a rear wall forming an interior volume operable to receive conventional electrical components therein. The electrical panel of the present invention includes an arc prevention member operably coupled to the side wall. The arc prevention member includes an upper portion and a lower portion contiguously formed. The upper portion is formed from a first segment and second segment having a void therebetween that is configured to couple to an edge of the side wall. The lower portion is integrally formed with the upper portion and extends outward therefrom into the interior volume of the panel box. The lower portion is arcuate in form.
