Front Access Electrical Enclosure Bus Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical enclosures are excessively large and inefficiently utilize space due to the need for back access to electrical bus members, requiring significant floor space and complicating maintenance and inspection processes.
Innovation Solution
An electrical enclosure design with sections that allow unobstructed front access to electrical bus members, enabling their inspection and maintenance without moving the enclosure or removing circuit breakers, by strategically arranging bus members within accessible sections of the enclosure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electrical bus members are disposed at the back of the enclosure for back access, then maintenance access is provided, but the enclosure requires excessive floor space and cannot be placed near structures
Solution Approach 1:
The patent inverts the conventional back-access arrangement by providing front access to electrical bus members. The bus members are disposed within the enclosure such that they are accessible from the front rather than requiring back access, thereby eliminating the need for excessive spacing from structures and reducing overall floor space requirements while maintaining maintenance accessibility
2Ease of operation
If the enclosure is disposed at a distance from adjacent structures for back access, then maintenance is enabled, but valuable floor space is wasted
Solution Approach 1:
The patent eliminates the conventional requirement for back access by inverting the access arrangement to provide front access to electrical bus members. This allows the enclosure to be disposed adjacent to structures without sacrificing maintenance access capability, thereby maximizing floor space utilization and eliminating wasted space
3Adaptability or versatility
If circuit breakers are disposed within the enclosure, then electrical apparatus is housed, but access to bus members requires removing circuit breakers or moving the enclosure
Solution Approach 1:
The patent segments the enclosure into distinct sections: a first section for housing circuit breakers and a second section for housing electrical bus members. This segmentation allows the bus members to be accessible from the front without requiring removal of circuit breakers, as they are disposed in a separate accessible section while maintaining the enclosure's ability to house electrical apparatus

AI summary
An electrical enclosure includes a housing having a front, a back, a plurality of sides, a plurality of sections disposed between the sides, at least one electrical apparatus, and a plurality of electrical bus members electrically connected to the electrical apparatus. The electrical apparatus is disposed within a first one of the sections of the housing, and a substantial portion of the electrical bus members are collectively disposed within a second one of the sections of the housing. At least the second one of the sections and the substantial portion of the electrical bus members collectively disposed therein are accessible from the front of the housing, regardless of whether the electrical apparatus is within or removed from the first one of the sections of the housing. An electrical bus assembly is also disclosed.
