WebThe cross sectional area of the Earth Continuity Conductor should not be less than the half of the cross sectional area of the thickest wire used in the electrical wiring installation. Generally, the size of the bare copper wire used as earth continuity conductor is 3SWG. But keep in mind that, don’t use less than 14SWG as earth wire.
WebAs the wire is made of copper, the earth wire provides a low resistance path to the ground. In the event of a fault, the live current passing through the case will follow this path to the... Webthe resistance (R) of the component and the potential difference (V) across the component 8 of 107 the greater the the resistance of the component the smaller the current for a given potential difference (pd) across the component. 9 of 107 potential difference = current x resistance 10 of 107 units for pd equation
