Earth sheath return system
WebA system is single point bonded if the arrangements are such that the cable sheaths provide no path for the flow of circulating currents or external fault currents. This is the simplest f orm of ... Webwire or earth return method. Thus, a single insulated or live cable conveys current from the insulated terminal of the battery, while the metal members of the engine and chassis provide a common return path for the various components, to the earthed battery terminal.
