    Electric Code Violation: Sharing Neutral Wires of Three Circuits Creates Hazardous Magnetic Field
    https://www.youtube.com/watch?v=-CaES0-yinI

    When neutral wires of two or more separate circuits are connected at other than the main panel the electicity has multiple return paths resulting in net currents. This can cause fire, shock and magnetic field hazards.

    Power plants and substations are the major components of the energy system. Aside from power transformers, the main parts of such a plant include instrument transformers, the protection and control system, as well as switching elements like circuit breakers and disconnectors. For a reliable supply of electricity, the correct operation of all individual components and their seamless interaction has to be assured – during the entire lifecycle of the plant.

    Should I install an ungrounded, solid, or high-resistance grounding system? That is the question asked by many designers and installers. The answer to this question depends on many factors. To make the correct decision, you must completely understand the pros and cons of each type of system. But first, you must also understand the different types of faults that can occur on your system and in what

    What is the difference between Bonding, Grounding and Earthing?
    https://electrical-engineering-portal.com/what-is-the-difference-between-bonding-grounding-and-earthing

    Ground or earth in a mains electrical wiring system is a conductor that provides a low impedance path to the earth to prevent hazardous voltages from appearing on equipment. Earthing is more commonly used in Britain, European and most of the commonwealth countries standards (IEC, IS), while Grounding is the word used in North American standards (NEC, IEEE, ANSI, UL).

    In TN Type Power Distribution System, in US NEC (and possibly other) usage: Equipment is earthed to pass fault Current and to trip the protective device without electrifying the device enclosure. Neutral is the current return path for phase. These Earthing conductor and Neutral conductor are connected together and earthed at the distribution panel and also at the street, but the intent is that no current flow on earthed ground, except during momentary fault conditions.

    Consumer has no any permission to mix Neutral with earth at his premises here earthing and grounding is the different by practice.

    Bonding
    Bonding is simply the act of joining two electrical conductors together. These may be two wires, a wire and a pipe, or these may be two Equipments. Bonding has to be done by connecting of all the metal parts that are not supposed to be carrying current during normal operations to bringing them to the same electrical potential.

    Bonding ensures that these two things which are bonded will be at the same electrical potential. That means we would not get electricity building up in one equipment or between two different equipment. No current flow can take place between two bonded bodies because they have the same potential.

    The primary reason for bonding is personnel safety, so someone touching two pieces of equipment at the same time does not receive a shock by becoming the path of equalization if they happen to be at different potentials. The Second reason has to do with what happens if Phase conductor may be touched an external metal part.

    The bonding helps to create a low impedance path back to the source. This will force a large current to flow, which in turn will cause the breaker to trip.

    In other words, bonding is there to allow a breaker to trip and thereby to terminate a fault.
