About This Item
C37.48-1987 is a technical standard for pole air switches, fuse disconnecting switches, and related accessories used in power, energy, and industry applications. It addresses equipment behavior and design expectations for switching and isolating circuits in outdoor distribution settings. For engineers, buyers, and maintenance teams, the standard helps define a common basis for evaluating performance, compatibility, and safe operation when specifying these switching devices and their supporting components.
About C37.48-1987
This standard focuses on the technical requirements associated with pole-mounted air switches and fuse disconnecting switches, along with the accessories that support their installation and use. C37.48-1987 is relevant where outdoor switching and sectionalizing equipment must be selected and applied with consistent electrical and mechanical expectations. It is commonly used as a reference for design review, procurement, and compliance checks in distribution equipment work, especially where dependable isolation and switching are important.
Where is C37.48-1987 used?
C37.48-1987 is typically used in utility distribution systems, substation-adjacent applications, and industrial power networks that rely on pole-mounted switching equipment. It is relevant when specifying devices for line isolation, feeder switching, or fuse-based protection on overhead circuits. The standard may also guide work involving accessories that affect mounting, operation, or maintenance of these assemblies. In practice, it supports coordinated decisions across engineering, purchasing, and field installation.
Importance in practice
The value of C37.48-1987 lies in helping ensure that switching and disconnecting equipment is specified and applied with consistent technical expectations. For pole air switches and fuse disconnecting switches, that can support safer operation, clearer procurement comparisons, and better alignment between design intent and installed hardware. It may also reduce uncertainty during testing, maintenance, and replacement planning by giving stakeholders a common reference for performance and construction considerations. C37.48-1987 remains useful as a superseded document for legacy equipment contexts.
