Free Elektor Circuit: Cable & Conduit Locator
Apart from the risk of a (dangerous) electric shock and the near certainty of a very massive short circuit that is the consequence of drilling into a cable, the aftermath of this mishap is no fun either. In any case, the damaged cable has to be replaced – and that is already not nice...
