What the reference means / 本表是什么
One identity row per HSIMC 249-entry ISO 3166-1 registry. Values describe typical household or office low-voltage AC mains and commonly reported plug/socket families. Multiple values indicate regional, island, or source variation. Four entries intentionally remain without unified figures.
249 是索引覆盖数量，不能把 ISO 地区代码误称为全部独立国家。这里不覆盖所有建筑、特殊回路、非洲／亚洲常见通用插座的安全性或电力公司实时供电条件。
What this does NOT prove / 不意味着什么
- No automatic plug-to-socket compatibility, even when geometry seems to fit.
- No confirmation of grounding, current rating, polarity, fuse selection, adaptor safety, voltage tolerance or product conformity.
- No approval of specific SKU, building installation, electrical work, local law, energy utility or MCP authority.
- Voltage adaptor ≠ voltage converter; portable charger specifications must be checked against the device label.
- Public references may disagree on nominal 220/230 V, historical systems, or uncommon plug variants. The differences are shown, not silently erased.
Sources & coverage / 来源及范围
ISO identifiers are reused from the existing HSIMC 249 identity registry. Public electrical information is compiled with new fields and original summaries; links are provided for traceability. Historical IEC lists are not represented as a current IEC endorsement. “Source differences” flags are comparisons, not a regulator finding.
