Past refits tend to leave old, abandoned wires in place.  This is especially true of wire trays running along Fir's corridors. The trays contained piles of  1/4" stainless steel braided wire, including the communication wires with two 20 gauge conduits.  This surplus of material occupied a great deal of space, and was rarely connected at either end.  This made wire tracing very difficult   Our new system has a different power distribution scheme so we are adding far fewer wires.

The first job was to remove the "dead" wires.  We began by identifying wires we knew to be dead from either the device or the panel.  When taking out an old device, we traced its power supply to the panel, and removed the wire run as well.  Similarly, when finding a leftover circuit breaker, we eliminated all  connections from the panel to its end.  Hundreds of pounds of wire was pulled out and taken away.  Fortunately we have recycling services nearby.
