| Jun 9, 2013 at 1:29 | comment | added | Butters | @TimCrossey At an ESD workstation the technician is tied to the same common ground (Earth) as the device and the mat to avoid being at a different electrical potential than the device, and allow a low resistance path for any static buildup generated from moving, friction, etc, to flow to ground. This does, as a side effect allow any unexpected current on the ground of the device to flow to ground through the cable, not through you, but that is not what the mat is designed to do | |
| Jun 9, 2013 at 1:27 | comment | added | Nick T | @TimCrossey it depends what you're working on; if it's low voltage or un-powered electronics, you want an ESD mat to bleed off charge (to ground). If it's powered high-voltage (mains, etc.) you do not want an ESD mat as it increases the risk of electrocution. | |
