IEEE 955-1962

955-1962 is a technical standard for clad switchgear, covering the construction and use of equipment where a conductive cladding or enclosure supports reliable electrical operation. In the context of power, energy and industry applications, it helps define expectations for design, materials, and performance so switchgear can be specified and evaluated with greater confidence. As an inactive standard, 955-1962 is still useful for understanding older practice and legacy equipment requirements.

About 955-1962

955-1962 addresses clad switchgear as a distinct equipment category rather than general power apparatus. It is typically relevant where enclosed switching and control assemblies must balance electrical insulation, mechanical integrity, and safe access for operation or maintenance. The standard’s value lies in giving a common technical reference for design and acceptance, especially when comparing products, reviewing documentation, or assessing equipment built to historical requirements. For buyers and engineers, 955-1962 helps frame what clad switchgear was expected to do in service.

Where is 955-1962 used?

This standard is most relevant in medium- and high-power installations that use clad switchgear as part of electrical distribution, switching, and protection assemblies. It may apply to industrial plants, utility-related facilities, and other engineered systems where enclosed switchgear supports controlled power flow and fault management. Because the subtitle points to clad switchgear specifically, 955-1962 is useful when dealing with legacy panels, replacement planning, or documentation for equipment that was originally specified under older electrical practice.

Importance in practice

In practice, 955-1962 helps support consistency in design review, procurement, and compliance checks for clad switchgear. Clear technical expectations can reduce ambiguity around construction details, performance limits, and safety-related features, which matters when equipment must integrate into established power systems. For operators and specifiers, the standard can also be a useful reference during maintenance or refurbishment of older installations. Using 955-1962 as a benchmark can improve comparability and help reduce operational risk.
