Big Clive on YouTube (not our Ancient Mariner) has released a video taking apart a fake Type C circuit breaker which is worth a look, but it is rather worrying what could be out there. https://www.youtube.com/watch?v=2TJEzdqtXlQ
I have seen that type of breaker before. An exact copy of the makers carboard box containing exact copies of the external appearance. The only way to tell the difference is to open them up or put them on a digital scale. One of the manufacturers told me that on one of their plastic molds there was a tiny cosmetic imperfection that appeared on the genuine MCBs, the makers of the fake items had even copied this defect.
Where can I get one of the MCBs with a clear plastic casing for teaching purposes?
