Extra connections between ground and circuit neutral may result in circulating current in the ground path, stray current introduced in the earth or in a structure, and stray voltage. [citation needed] Extra ground connections on a neutral conductor may bypass the protection provided by a ground-fault circuit interrupter. Signal circuits that ...
Hot is any line or neutral conductor (wire or otherwise) connected with an electrical system that has electric potential relative to electrical ground or line to neutral. Ground is a safety conductor with a low impedance path to earth. It is often called the "ground wire," or safety ground. It is either bare or has green insulation. [1]
In a TN (terra–neutral) earthing system, one of the points in the supply transformer is directly connected with Earth, usually the neutral-star-point in a star-connected supply transformer, the same point from which a neutral (N) connection would be provided. Exposed-conductive-parts within a consumer installation are connected with Earth via ...
Voltage is defined as the difference of electric potentials between points in an electric field. A voltmeter is used to measure the potential difference between some point and a convenient, but otherwise arbitrary reference point. This common reference point is denoted "ground" and is designated as having a nominal zero potential.

Electrical equipment may be designed with a floating ground for one of several reasons. One is safety. For example, a low-voltage DC power supply, such as a mobile phone charger, is connected to the mains through a transformer of one type or another, and there is no direct electrical connection between the current return path on the low-voltage side and physical ground (earth).
