IEEE C37.23-2015

C37.23-2015 is a technical standard for enclosed bus in power, energy, and industrial applications. It addresses the design and performance expectations for enclosed bus systems used to carry electrical power in protected assemblies, where enclosure, insulation, and mechanical arrangement are important to dependable operation. As a result, C37.23-2015 helps engineers, specifiers, and purchasers compare equipment on a common basis and support safer, more consistent application in electrical infrastructure.

About C37.23-2015

This standard focuses on the enclosed bus configuration and the requirements that influence how such systems are built and evaluated. In practice, that may include construction features, electrical ratings, insulation coordination, and other characteristics that affect serviceability and durability. C37.23-2015 is relevant when a project calls for a defined enclosed bus arrangement rather than an open or loosely protected power path. It provides a reference point for technical review, procurement, and compliance decisions in engineered electrical systems.

Where is C37.23-2015 used?

The standard is typically used in facilities and equipment installations where enclosed bus is employed to distribute power between major components. That can include industrial plants, utility-related installations, and other power system environments that require a protected conductor assembly. C37.23-2015 is also useful during specification writing, equipment selection, and acceptance review for enclosed bus applications. Its scope is most relevant when space, protection, and controlled power transfer are important to the overall system design.

Importance in practice

In practice, C37.23-2015 supports consistent design and evaluation of enclosed bus systems, which can reduce uncertainty during engineering and purchasing. Using a recognized standard helps align expectations for ratings, construction quality, and performance-related checks. That matters for safety, maintainability, and system reliability, especially where enclosed bus forms part of a larger power distribution network. It can also simplify comparison between products and improve documentation for compliance, testing, and project approval.
