Sample text

This, of course, presents a low-resistance path for fault currents to operate the protection. In summary, connecting metalwork to earth places that metal at or near zero potential and bonding between metallic parts puts such parts at a similar potential even under fault conditions. Add to this a lowresistance earth fault return path, which will enable the circuit protection to operate very fast, and we have significantly reduced the risk of electric shock. indd 54 27/05/2015 10:36 The Importance of Earthing and Bonding 55 Earth fault loop impedance As we have just seen, circuit protection should operate in the event of a fault to earth.

30 Method B. Where cables enter KO boxes, holes should have grommets installed. In general, it is usual to either clip cables directly to a surface and give added protection from danger by the plasterer’s trowel by covering the cable in PVC or metal Top-Hat section, or enclose it in oval conduit. There are, however, occasions when a specification demands that all cable runs are chased in to achieve full plaster cover. Also at first-fix stage and before cables are run, it is usual to drill or notch joints.

5 Simplified earth fault loop path. 5 is a simplified version of the loop path. e. Zs = Ze + R1 + R2 we also have, from Ohm’s law, the value of the fault current that would flow from I= U0 Zs where U0 is the nominal voltage to earth (230 V).
