    There need to be more accurate definitions used. Liable to introduce a potential. At what resistance? What is the current capacity?


    A screw into brickwork will introduce an external potential, (usually earth), just at an incredibly high impedance. With alternating currents, ANYTHING conductive will have a path to earth.
