ESD safety when working across multiple workbenches/tables
You said &quot;the ESD bench mount is attached to the mains&quot;, which sounds to me like it's directly connected to the ground lead of a power outlet somewhere. Please don't do this! ESD safety equipment usually uses a series resistor between you and the ground, to avoid high currents flowing through your body in case you accidentally touch something that's at a high voltage. Based on this question and its answers, that resistance can be around 1-2.5 MΩ. This answer to the same question explains nicely how that protects you as well as the electronics you work on.
