well… i mean…
-
you could get a mean static shock to a shielded cable which is properly grounded, then think it shocked you (when really you shocked it hah!)
-
i’ve seen ethernet conductors being used for POTS and touching a wire with a 120v ring signal coming in doesn’t feel good.
-
power and data closets are often in the same place, with wires running right next to each other… never underestimate the stupidity of people.
Even if you got a little shock from it, it wouldn’t do anything to your spark 2. any ongoing sensation is probably just you focusing on it (psychosomatic)
