2. FOR 14 VDC INSTALLATIONS, THE USE OF TWO AIRCRAFT POWER AND TWO AIRCRAFT GROUND CONTACTS IN THE CONNECTOR IS RECOMMENDED
FOR EACH POWER BUS CONNECTION. 28 VDC INSTALLATIONS ONLY REQUIRE ONE AIRCRAFT POWER AND ONE AIRCRAFT GROUND CONTACT IN THE
CONNECTOR FOR EACH POWER BUS CONNECT
ION.
3. IN SOME CASES, A LARGER GAUGE WIRE SUCH AS #18 OR #20 AWG WIR
E MAY BE USED FOR POWER CONNECTIONS. SPECIAL THIN-WALL HEATSHRINK
TUBING IS PROVIDED TO INSULATE THE EXTENDED BARRELS INSIDE THE BACKSHELL. IF #18 BARREL CONTACTS ARE USED, ENSURE THAT NO TWO CONTACTS ARE MOUNTED DIRECTLY ADJACENT TO EACH OTHER, THIS MINIMIZES THE RISK OF CONTACTS TOUCHING EACH OTHER AND SHORTING TO ADJACENT PINS AND TO GROUND.
