Abstract: Vertical bus bars conducting high amperage electric current extend inside a bus way in tall buildings, and feeder connections are on each floor to a local circuit. The improvement is that the feeder connections are entirely outside the bus way. Each feeder connection includes individual insulated lugs conductively and permanently secured to the respective bus bars and extending through slots in an insulating plate into a switch or circuit breaker and fuse box entirely outside the bus way. All connections to local circuits are made in the switch box or circuit breaker box outside the bus way thereby avoiding shorting in the bus way.
