Gang Box Driver Compartment for Code-Compliant Circuit Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical enclosures, such as gang boxes, face challenges in accommodating drivers due to space constraints and regulatory requirements for separating high-voltage and low-voltage circuits.
Innovation Solution
The design of an electrical gang box with a main compartment for electrical controls and a lower compartment for drivers, featuring rails and a divider panel that can be adjusted to separate voltage circuits, allowing for efficient placement and connection of drivers within the enclosure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a driver is placed in a typical gang box, then space utilization is improved, but electrical code compliance deteriorates due to required separation of high-voltage and low-voltage circuits
Solution Approach 1:
The gang box is divided into separate compartments using a divider, creating distinct spaces for high-voltage and low-voltage circuits. This segmentation allows both voltage types to coexist in the same gang box while maintaining code-required separation, thus improving space utilization without compromising electrical code compliance.
Solution Approach 2:
Different regions of the gang box are assigned different functional qualities - one compartment for high-voltage controls and another for low-voltage drivers. This local differentiation allows each compartment to serve its specific purpose while maintaining overall code compliance within the unified gang box structure.
2Adaptability or versatility
If a multiple-gang box is used to accommodate both switch/dimmer and driver, then driver placement is enabled, but space for switch or dimmer is reduced
Solution Approach 1:
The multiple-gang box is segmented into dedicated compartments using dividers, with one compartment allocated for the switch or dimmer and another for the driver. This segmentation ensures that each component has sufficient space while enabling the gang box to accommodate both types of devices simultaneously.
Solution Approach 2:
The multiple-gang box structure is designed to serve multiple functions - housing both high-voltage control devices (switches, dimmers) and low-voltage drivers within the same enclosure system. This multi-functionality allows a single gang box installation to fulfill both control and power conversion needs.
3Volume of moving object
If a driver is hung from the gang box using knock-outs, then space within the gang box is conserved, but fire protection capability deteriorates
Solution Approach 1:
Instead of hanging the driver externally through knock-outs, the gang box is segmented to include a dedicated internal compartment for the driver. This internal compartmentalization maintains the fire-containing enclosure integrity while still conserving external space and providing organized separation of circuits.
Solution Approach 2:
The driver compartment is nested within the gang box structure itself, with the driver housed inside the fire-rated enclosure rather than externally. This nesting approach preserves the fire protection capability of the gang box while accommodating the driver in a space-efficient manner.

AI summary
An electrical gang box adapted for use with drivers is disclosed. The electrical gang box includes a main compartment with a front opening sized and adapted to accept an electrical control and structure around the front opening to secure the electrical control within the front opening and within the main compartment. The electrical gang box also includes a lower compartment that extends below the main compartment, is set back from the front of the main compartment and is open to the main compartment along an upper portion. The gang box may also include one or more pairs of rails disposed on opposite interior walls. In such cases, a divider panel is sized to slide into and extend between the rails to divide the junction box. Multiple-gang boxes with these features are also disclosed.
