A method of managing movement of an electric cable that is configured to provide power to a mobile machine. The method includes determining an initial boundary of an isolation zone in which the cable lies, for a first location of the machine. The initial boundary is divided into a first static boundary and a first dynamic boundary. The first static boundary surrounds a static isolation sub-zone of the isolation zone, and the first dynamic boundary surrounds a dynamic isolation sub-zone of the isolation zone. A second dynamic boundary surrounding the dynamic isolation sub-zone is determined, based on a second location of the machine when the machine moves from the first location to the second location, such that the cable lies within the second dynamic boundary. The first static boundary is maintained when the machine is in the second location.
