Grounded vs non-grounded appliance couplers
The V40 engineering sidecar explicitly distinguishes grounding only for selected IEC C5/C6, C7/C8 and C17/C18 forms. This table does not extrapolate that label to other IEC families whose current sidecars do not publish the same boundary.
| IEC form | Role | Grounding distinction | Documented count |
|---|---|---|---|
| IEC 60320 C5 cord connector | IEC 60320 C5 grounded cord connector | Grounded | 3 |
| IEC 60320 C6 appliance inlet | IEC 60320 C6 grounded appliance inlet | Grounded | 3 |
| IEC 60320 C7 cord connector | IEC 60320 C7 non-grounded cord connector | Non-grounded | 2 |
| IEC 60320 C8 appliance inlet | IEC 60320 C8 non-grounded appliance inlet | Non-grounded | 2 |
| IEC 60320 C17 cord connector | IEC 60320 C17 non-grounded cord connector | Non-grounded | 2 |
| IEC 60320 C18 appliance inlet | IEC 60320 C18 non-grounded appliance inlet | Non-grounded | 2 |
Electrical safety boundary.
Grounded/non-grounded classification is not a replacement-cord approval. Voltage, current, temperature class, equipment class, regional requirements and exact manufacturer instructions remain separate checks.
