|Grade A (100% Correct Elaborations)
Electromagnetic Interference (5.5.5.5)
caused when electromagnetic fields (radio waves) induce high-frequency voltages in a wire or
component. (AC 43.13-1B 11-89)
Grounding (5.5.5.5)
Establishing a physical wire path that gives electricity a path to earth/ground.
Bonding (5.5.5.5)
Connection of non-current carrying conductive elements ie. enclosures and structures.
Conductor plating (5.5.5.1)
Copper wire plated with Tin, Silver, or Nickel. Tin is the most common. wire plating has a
slower oxidation rate than bare copper.
Voltage drop in wires (5.5.5.1)
Should not exceed 2% of the regulated voltage when the generator is carrying rated current or the
battery is being discharged at 5 minute rate.

The allowable voltage drop in a 28 volt continuous circuit is:
a. 1 volt
b. 2 volts
c. 5 volts
d. 4 volts
a. 1 volt
Voltage rating (5.5.5.1)
The voltage rating of a cable is the highest voltage that may be continuously applied to a
completed cable construction in compliance with the relevant cable standard or specification
Shielded wire (5.5.5.1)
Electrical wire that is enclosed in a braided metal jacket. Electromagnetic energy radiated from
the wire is trapped by the braid and is carried to ground.
