Discussion Overview
The discussion revolves around the labeling and wiring of a 120VAC power cord with an IEC connector. Participants explore the discrepancies between the expected labeling (L, N, Earth) and the actual voltage measurements, leading to confusion and concern about potential safety issues with such cables.
Discussion Character
- Debate/contested
- Technical explanation
- Exploratory
Main Points Raised
- One participant reports measuring 0V between L and Earth and 120VAC between N and Earth, suggesting a labeling issue.
- Another participant questions whether the female end of the cable has L and N swapped compared to the male receptacle.
- Some participants note that the labeling on the IEC connector does not match the actual wiring, with one participant stating that the N label is connected to the hot side of the male plug.
- There is mention of different standards for power cords in various countries, which may contribute to confusion.
- One participant discovers that multiple cables from different vendors have different wiring configurations, raising concerns about the consistency of IEC power cord wiring.
- Another participant expresses concern that incorrect labeling could mislead those learning about electrical wiring, even if the cable functions correctly in standard use.
- Concerns are raised about the safety implications of potentially faulty cables being widely available, with one participant sharing their experience of testing multiple cables and finding one wired incorrectly.
- Discussion includes reflections on the reliability of the supply chain and the challenges of ensuring product safety for consumers.
Areas of Agreement / Disagreement
Participants express a range of views on the labeling and wiring of the power cord, with no consensus reached on the implications of the discrepancies. Some agree on the existence of faulty cables, while others emphasize the need for caution and verification.
Contextual Notes
Participants note the potential for confusion due to varying international standards for power cords and the implications of incorrect wiring. The discussion highlights the importance of verifying the wiring of power cables before use.
