Installation Procedure 2.5.4 Spider Grounding Installation The Spider Grounding Kit, part of the connector kit, allows shielded cables that go to a backshell to be terminated to the backshell. Twenty AWG #24 wires are available to splice with the cable shields. The wires all terminate to a terminal that is fastened to the backshell. A single AWG #16 wire provides ground reference to the terminal, thereby grounding all Spider leads to the aircraft. Spider Kit terminals are screwed to the backshell using the tapped holes provided.
