Modular Meter Compartments for NEC-Compliant Service Disconnect Layouts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multi-family metering devices with multiple service disconnects are inadequately designed, as they are often housed in a common wiring compartment, failing to meet the NEC 2020 code requirement of having each service disconnect in a separate compartment.
Innovation Solution
A multi-family metering device with modular meter compartments, where each service disconnect has its own individual compartment, with enclosures that can be attached to either side of a pull section, creating a unique layout that separates each disconnect into distinct sections rather than a common compartment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple service disconnects are housed in a common wiring compartment, then the device complexity is reduced and manufacturing is easier, but compliance with NEC 2020 code requirements is not achieved and safety is compromised
Solution Approach 1:
The device is divided into multiple separate modular meter compartments, each housing a single service disconnect. These compartments are physically separated by partitions and can be independently accessed, eliminating the common wiring compartment design while maintaining overall device functionality.
2Reliability
If separate compartments are provided for each service disconnect, then NEC 2020 code compliance and safety are improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
Each modular meter compartment is designed as a universal module that can be configured in different arrangements to accommodate various numbers of service disconnects. The standardized design with consistent mounting interfaces and wiring patterns simplifies manufacturing despite the increased complexity of having multiple separate compartments.
3Adaptability or versatility
If modular meter compartments are made attachable to both sides of pull section, then installation flexibility and adaptability are improved, but device complexity increases
Solution Approach 1:
The modular meter compartments are designed with detachable connections that allow them to be attached to either side of the pull section, creating a flexible configuration system. This dynamic arrangement enables installers to adapt the device layout to different installation spaces while using standardized connection interfaces that minimize overall complexity.

AI summary
A multi-family metering device including a plurality of modular meter compartments where the modular meter compartments are interconnected and laid out in a horizontal section. The multi-family metering device comprises a pull section having a first enclosure and a plurality of modular meter compartments for multiple service disconnects with an individual modular meter compartment provided for each service disconnect such that each modular meter compartment of the plurality of modular meter compartments having a second enclosure different from the first enclosure. One or more modular meter compartments of the plurality of modular meter compartments are configured to be attached to both or either side of the pull section. The second enclosures are joined together instead of providing one enclosure with a common wiring compartment that is divided into different sections.
