# Parts of electricity distribution or control apparatus

## 1. Scope and Applicability

This PCR covers factory-gate production of discrete parts designed solely or principally for electricity distribution or control apparatus. Covered examples include conductive connections and contacts, busbar links, terminals, mechanical operating parts, dedicated housings, mounting pieces, and insulating supports supplied as parts rather than complete apparatus.

The foreground boundary begins with production-ready purchased inputs at the factory gate and ends with a conforming finished part ready for dispatch. It includes applicable forming, moulding, machining, joining, assembly, inspection and testing, aqueous surface treatment, coating preparation, and on-site thermal energy. Upstream production of purchased inputs must be represented by linked datasets.

Complete apparatus, equipped boards or cabinets, optical-fibre connectors, general-purpose fasteners, buildings, capital equipment, installation, use, distribution after the factory gate, and end of life are excluded. Packaging is outside the reference-product mass; when included in study scope, each actual packaging component must be added as a separate atomic exchange.

Because CPC 46220 spans materially different parts, each dataset must represent one declared part or homogeneous family. Unlike functions, materials, voltage classes, or routes must not be averaged without disclosure and production-weighted aggregation.
