That means the signal is entirely in the tin layer, if one is present. Not a good thing, as tin is not a very good conductor. Tin has about seven times the resistance of copper). So anything at 1MHz or higher should not have a tin layer. It needs to be bare copper. That means video cable, digital audio cable, RF coax or Category data cables all need to be bare copper. No tinned copper.
The neutral conductor is connected to earth at the building point of supply, but no common path to ground exists for circuit current and the protective conductor. In the TN-C system, a common conductor provides both the neutral and protective grounding.round is more common in North American English, and earth is more common in British English.) Under normal conditions, a grounding conductor does not carry current. Neutral is a circuit conductor that normally carries current, and is connected to ground (earth) at the main electrical panel.
