IEEE 48-1948

48-1948 is the AIEE Standard for Potheads, a technical document focused on power-system components used to terminate and protect cable connections. In the context of power, energy, and industrial applications, it addresses the design and application of potheads, helping define expectations for insulation, mechanical arrangement, and dependable service. For engineers and purchasers working with high-voltage cable terminations, this standard offers a clear reference for consistency and safer equipment selection.

Overview of 48-1948

As an AIEE standard, 48-1948 belongs to an early body of electrical engineering guidance aimed at improving uniform practice for specialized components. Its subject matter points to potheads, the term commonly used for cable termination assemblies in power installations. The document is relevant where conductors must transition from cable systems to connected apparatus while maintaining electrical integrity and environmental protection. This makes the standard useful for understanding the expected construction, performance, and application context of these termination devices.

Typical use cases

48-1948 is typically relevant in installations where power cables are brought into equipment, such as transformers, switchgear, generators, or other industrial electrical assemblies. It may also be used when evaluating replacement parts, reviewing legacy drawings, or comparing termination hardware for compliance with historical engineering practice. In utility and plant settings, the standard helps frame how potheads are specified and assessed for reliable cable entry, insulation support, and orderly integration with surrounding components.

Why it matters

This standard matters because potheads are critical interface points in electrical systems, and poor specification can affect insulation performance, mechanical stability, and long-term reliability. Using 48-1948 as a reference can support more consistent design review, procurement decisions, and inspection criteria for older or specialized installations. It also helps reduce ambiguity when documenting equipment requirements, especially where legacy terminology and traditional power-engineering practices still influence maintenance or replacement work.
