IEEE 48-1962

48-1962 is the AIEE Standard for Potheads, a technical document focused on cable termination hardware used in power and industrial electrical systems. It addresses the design and application of pothead assemblies, which are important for sealing, insulating, and protecting cable ends where conductors enter equipment or other connected systems. For engineers, purchasers, and maintenance teams, 48-1962 provides a reference point for consistency and performance in these critical connection points.

About 48-1962

This standard sets out expectations for potheads in the context of electrical power and related engineered systems. In practice, a pothead is used to terminate cables in a way that supports insulation integrity, environmental protection, and reliable electrical connection. 48-1962 is relevant to equipment where dielectric behavior, material selection, and mechanical arrangement can affect service life and operating safety. As a superseded standard, it is still useful for understanding historical design practice and legacy installations.

Where is 48-1962 used?

48-1962 is typically associated with cable terminations in power stations, substations, industrial plants, and other installations where heavy-duty conductors must be brought into enclosed equipment. It is most relevant where insulated cables require a pothead-style termination to manage stress, moisture, and contamination at the connection point. The standard may also be consulted when working with older apparatus, replacement parts, or documentation for legacy power and energy systems that still rely on this type of termination.

Importance in practice

In practice, this standard helps support safer and more consistent pothead design, procurement, and inspection. Clear requirements can reduce the risk of insulation failure, leakage paths, and poor termination workmanship, all of which can affect reliability in power applications. For organizations maintaining older infrastructure, 48-1962 can also help align replacement components and testing expectations with the original technical basis. Using a defined reference improves repeatability and helps limit uncertainty during specification and review.
