Chapter 11, Section 13-15 Flashcards
What is the purpose of a conductive chemical surface treatment, such as Alodine, on aluminum surfaces in bonding connections?
To prevent corrosion
What is the purpose of a suitable noncorrosive sealant in bonding and grounding connections exposed to a salt spray environment?
To prevent corrosion
What is the role of engineering approval in splicing individual wires in a group or bundle?
To allow periodic inspection
What should be used to prevent the terminals on adjacent studs from contacting each other?
Terminal strip barriers
What is the maximum resistance that bonding jumpers should have?
.003 ohm
Why should splices in bundles be staggered?
To minimize any increase in the size of the bundle
Under what conditions should splicing of electrical wire be kept to a minimum?
In locations subject to extreme vibrations
What type of terminal lugs should be used for copper wire?
Solderless crimp style
What types of wires require approved data for splicing?
Both Multiplex bus and large gauge wire & Power wires and coaxial cables
What is the purpose of a low-impedance path to aircraft structure for electronic equipment?
To reduce EMI
What should be used to prevent a loose insulator from failing to provide circuit isolation?
Feed-through insulator design
What should be used to connect aluminum wire to aluminum terminal lugs?
MS-25440 flat washers
What should be used to ensure that the crimp depth is appropriate for each wire size?
High quality ratchet-type crimping tool
What is the process of electrically connecting conductive objects to either a conductive structure or some other conductive return path for the purpose of safely completing either a normal or fault circuit?
Grounding
What is an exception to the rule of having only one splice in any one wire segment?
To adjust wire size to fit connector contact crimp barrel size
To splice multiple wires to a single wire
When attaching to the spare pigtail lead of a potted connector
All of the above
