It would appear that the flight crew was unfamiliar with this procedure. This procedure should be a fundamental requirement for all flight crews.
Most airplanes flying today have dangerous wire installations on board their aircraft.
737 and 757's that were built after 1992, that have BMS 13-60 wire, are protected from having insulation electrical arc resistance fires. In addition, we are the first company in the aerospace industry to issue a wire and cable specification that uses SPC as the basis for assuring the quality of the product. BMS 13-60 is the standard to which the rest of the industry will aspire. I know, because I participated in the development and testing of this wire and developing the test laboratory. An arc tracking fire will continue to travel along the wire bundle as long as there is power on one of the wires in the wire bundle.
