This isacco mplishedthrough the useof two GeneralElectric typeSW-4 automaticsectionalizingswitches at apoint where twolines branchfrom the mainline. The Ore-gon Avenueand the RaceTrack lines re-ceive their power from the Englewood or South Buttelines through sectionalizing switches S, and The contactors in the automatic substation for theOregon Avenue and Race Track feeders are used to en-ergize these circuits to close the automatic sectionalizingswitches in case they open through overload, as thebreakers for the Englewood or South Butte feederswould not open to equalize the separate sections. TheOregon Avenue and Race Track feeders will (with a re-duction in voltage) carry the loads of these stations incase the power is not on the Englewood section. Instead of using a single contactor for the feedersfrom the automatic substation, which
