I bought an ESD mat. It has a grommet to attach a ground wire.
How do you do this? Is there an industry standard?
I am an electrician, so I should know and I do. But what is electrically approved per code doesn't make sense for type of equipment involved. The code says ground should enter a dwelling from one and only one place. That means service entrance. So I can wire ground to the prong of American standard outlet. BUT, ground wire goes all the way back to breaker box and then back to the main feed to a service entrance, then FINALLY to the ground rods. That's pretty high impedance. It's also possible to pickup hum this way.
I can actually ground fright outside the window. It will be a short path, and that ground is BONDED to the main ground outside. But, if I do, if there are any current on ground (which it shouldn't but....) it will create a voltage differential and then ground loop. Also, this is against the code.
There must be an industrial standard in electronics industry. Does anyone know?
