Insulation is not perfect. It leaks current. It's the reason GFCI protection at the source end of long DB conductor will trip.

Older PC monitors had a leakage current that could exceed GFCI operation values.
It was listed in their specs.

You know people say that some stuff is a conductor and other stuff is an insulator? That's not really true. Everything is a conductor, but some conductors really suck. We use the worst conductors as insulation.
Then there is also capacitive leakage current which is the flow of current due to charging and discharging the natural capacitor formed by conductors being in close proximity.

Leakage current is pretty much any current that flows in an undesired path (leakage) in a normally functioning system. This would include the tiny current through a completely intact insulation system.
