| I had a friend who was easily teased by this, but he was quite right, and you are wrong. Kettle leads in the U.K. have never been C13, and "kettle lead" for a C13 power lead is a misnomer just as much in the U.K. as it is elsewhere. When kettle power cords weren't captive, as they are nowadays, they weren't C13. Non-captive kettle cords from the middle 20th century were round pin, for starters, and not like the (later) IEC standard at all. Here's a round-pin electric kettle from the 1960s, for example: https://www.modip.ac.uk/artefact/aibdc-02510 And "hot condition" or "high current" leads for other devices are not C13 now. Here's a high current power lead from Toolstation, for example: https://www.toolstation.com/uk-plug-to-hot-iec-lead/p21431?u... It's mis-labelled "C13" but it's clearly a C15 with a notch. Contrast with an actual C13 lead from Toolstation: https://www.toolstation.com/uk-plug-to-iec-lead/p29256?utm_s... Here's a hot condition power lead from BKA, for another example, which is again a C15: https://www.bka.co.uk/iec-c15-hot-condition-power-leads |
The website it's from has a fair number of kettles from the relevant time period (1980s and early 90s). These two (which seem to be variants of the same model) [1,2] have an OKish view of the power connector and look more likely to fit C13 than C15 from what I can make out (no notch). This one [3] is clearly for C15 though, but as I say it's not a surprise that some exist.
