About This Item
PC62.62/D2, Oct 2017 is a technical standard focused on protective devices (SPDs) for use on the load side of service equipment in low-voltage AC power circuits rated 1000 V and less. It addresses a narrow but important part of power-system protection, where surge protection must be coordinated with downstream equipment and installation practices. For electrical engineers, specifiers, and procurement teams, this document helps define a consistent basis for evaluating SPD design, application, and compliance.
What is PC62.62/D2, Oct 2017?
PC62.62/D2, Oct 2017 sets out technical guidance for surge protective devices intended for low-voltage AC power circuits on the load side of the service equipment. In practical terms, it helps frame how these devices are described, assessed, and used in electrical systems where transient overvoltage protection is needed. The document is relevant to components, circuits, devices, and systems work, especially when comparing protective performance and installation suitability for a specific power application.
Where is PC62.62/D2, Oct 2017 used?
This standard is typically used in low-voltage distribution environments where SPDs are installed to protect downstream panels, branch circuits, and connected equipment. It is especially relevant in facilities that rely on sensitive electrical and electronic loads, such as industrial power systems, commercial buildings, control cabinets, and other AC installations operating at 1000 V or less. PC62.62/D2, Oct 2017 is useful wherever surge protection must be selected and applied with attention to the load-side location.
Why is PC62.62/D2, Oct 2017 important?
PC62.62/D2, Oct 2017 matters because surge protective devices must be chosen and applied carefully to reduce risk to equipment and improve system reliability. A clear technical standard supports more consistent design decisions, testing expectations, and product comparison during procurement. It also helps reduce uncertainty around performance in low-voltage AC circuits, where incorrect SPD selection can lead to poor protection or coordination issues. For organizations managing electrical safety and uptime, the standard provides a practical reference point.
