The useful distinction
Recognize it. Then verify it.
IEC 60320 identifies the C1 connector within the Class II 0.2 A coupler family, paired with the C2 inlet. [C299A]
Interpower's Rev10-17 chart labels C1 as the cord connector paired with C2, in its Class II cold group. Its connector label explicitly says non-rewireable only. [C299B]
Bulgin's manufacturer overview describes the C1/C2 family as a 2-conductor system with 70 degrees C temperature context. This is not a terminal-position map. [C299C]

Specifications and limits
| Documented identification | Interpower’s IEC 60320 overview identifies the C1 connector with the C2 inlet in the Class II 0.2 A coupler family. [C299A] |
|---|---|
| Mechanical dimensions | No independently reviewed mechanical drawing in V50; do not use this page for fabrication, fit testing or tolerance work. |
| Engineering pinout | Source-checked engineering profile available; independent review pending. Open engineering profile → |
| Verified device list | Not included. Check exact device and accessory documentation. |
Use only the source-backed family, role or position count for identification. Resolve electrical ratings, protocol generation, lane wiring, signal assignment, cable construction and exact device support from the relevant equipment and component documentation.
Before you connect
What to check
- Identify the exact connector family and variant from the equipment or component documentation.
- Keep physical form, contact count, protocol, electrical rating and device support as separate facts.
- Do not force, rewire, adapt or install from this recognition record; resolve the remaining requirements first.
What is not established
This field note does not approve a connection, adapter, cable assembly, rewiring scheme, energized-work procedure or fabricated part. It intentionally omits unsupported pin assignments and mechanical tolerances.
