via parallel conductors requires “bridges” at separating distances or phases of 2 – 3 m in order to reduce the line losses. If the rail length between the condenser bank and the wall-side furnace connection is 3 m, such a phase bridge should be used here in the area of the transition point. Bridging should also be used for longer rail lengths and also current pipes. In the area of switches for switching off or over, the rail guide must run without any branching for at least 1 m in front of and behind the switch. Lateral outlets should be avoided at high-tension switches, since the current takes the path of least resistance. If for example both outlets are to the same side, the poles on the other side will be subjected to less load than those in the area of the current supply and off-take.
