Switching off the live wire means that there will be no current in the neutrals served by that breaker, effectively floating them, so - other than a momentary spike caused by charge ... WebThen the other-wire becomes live. In (b) the battery negative has been connected to earth. It is grounded or neutralised and the other wire is 9 V with respect to earth. One of the advantages of neutralising is that no fuses are required in the neutral line as there is no significant voltage with respect to earth.

WebJan 31, 2016 · $\begingroup$ If you earth yourself and com into contact with a live wire, the path of least resistance between live wire and earth is through you. Put another way: the resistance of the path wire - you - earth is lower than otherwise, so more current. What you want to do is earth the electrical system (without yourself in the path). $\endgroup$ WebJul 1, 2024 · Definition of Terms. Earth ground: The point where the grounding system will run to the planet. This can be achieved with a copper rod hammered into the soil or a connection to a water pipe (ideally copper).
