Hi guys, I have been rooting around for an hour or more trying to find the authentication of this commonly observed symbol for what I guess we would take to be
dc supply without the text of course
I havent found it in IEC standards or CAD symbol library etc
Bear with me here as IMHO it has important implications - particularly in the field of electrical protective devices. You find this symbol slipped into the markings on fuses and switchgear often from the PRC. This crops up in device offered for sale for use with Solar systems and associated batteries, inverters, switchgear, fuse protection.
Without text this symbol on a drg might imply a screened cable - for example.
Anyone know of an official source for this symbol used for dc supplies? BTW the official IEC symbol is
=BTW as a corollary to the above, you are surely aware of the widespread use of a fake CE marking
https://www.pat-testing-training.net/articles/ce-mark.phpThis has shown to be a particular problem in electrical gear from the PRC eg mobile chargers and dangerous outdoor lighting fixtures (metal case 3 wire, but earth not connected, not IP65) a fatality occurred in a pub beer garden.) and so on.
The EU CE mark in a self certified joke dont trust it
Fake CE means "China Export"
