I'm building my new lab and I'm not sure where to ground since I live in the Netherlands; we only have hot and neutral available, I don't see a third a hole.
I understand I should get an ESD mat and wrist strap that includes the 1Mohm resistor. And ground these 2 with a common-point ground as shown here http://documents.desco.com/pdf/tb-2000.pdf
The ESD mat should also include a 1Mohm resistor in order to soft-ground it as well, but I'm a bit confused as to why wouldn't the non-conductive top surface be considered a soft-ground for the bottom-conductive layer.
However, my question is about how should I ground the the common-point ground. Should I unscrew the third hole on my wall socket a bit and tie it there? I'm a bit lost how to continue, all the tutorials I see on the internet always include a dummy plug with ground connection to a hot-neutral-ground wall socket, which I don't have.
Any help is appreciated!
Is the top right cable (kinda grey-ish) the ground that I need? If so, then can I just replace with the other outlets containing a ground prong?
