If you happen to touch the metallic part at that moment you will be zapped. But if the metallic part of the appliance is earthed, the charge will be transferred to earth instead of accumulating on the metallic part of the appliance. Current don’t flow through earth wires in electrical appliances, it does so only when there is problem and only to direct the unwanted current to earth in order to protect us from severe shock.
However, if excessive current is not earthed, appliances will be damaged without the help of fuse in place. You should note that excessive current are earthed at their generating stations which is why earth wires carries very little or no current at all. It therefore implies that it is not necessary to earth any of the wires (live, earth and neutral wires) contained in a PVC. Earthing the live wire is catastrophic.
We are specialized in manufacturing different types of Earth Bars like -Way Earth Bars, Disconnecting Link, Copper Earth Bars, Neutral Earth Bars, and Brass Earth Bars, which are available in various size, configuration, and capacities along with different finishing as per requirements. We are even engaged in manufacturing various types of Earth Bars that are available in various lengths, widths, and thicknesses as per customer needs. Our complete range of Earth Bars is available with pre-drilled fixing holes and different dimension specifications.
I have seen a person killed simply because a live wire got cut from overhead pole and fell to the ground while the ground was wet. Excessive current is earthed at generating stations and if at all the earthing is not efficient due to fault, earth fault interrupters will be there to help. Fuse help only when the power transmitted is above the rating of our appliances, it blocks the current from reaching our appliances by blowing off and protecting our appliances in the process.
نحوه نصب به این صورت است. که ابتدا شما موقعیت و شرایط محیطی خود را از میان دو روشی که گفته میشود انتخاب کنید. دو روش موجود برای انجام ارتینگ عبارت میشوند از روش زمین عمقی و روش زمین سطحی که در ادامه به توضیح هر دو میپردازیم.
