Before performing maintenance on the secondary distribution center (SDC) you - ANS -ensure
all power is removed.
\Besides conductor size, what is another important factor to consider when reducing voltage
drop in an electrical circuit? - ANS -Circuit distance.
\For proper operation, you need to keep the telescoping floodlight set generator output between
- ANS -233 and 247 VAC.
\How do you begin the procedure for installing the emergency airfield lighting system obstruction
lights? - ANS -Install the batteries into the fixture.
\How do you deenergize the transformer windings of one secondary distribution center (SDC)
without deenergizing any of the interconnected SDCs? - ANS -Pull the three fused disconnects
in the high-voltage compartment.
\How do you remove the red lens from an obstruction light? - ANS -Loosen the screws holding
the lens in place, turn it to the right, and pull it straight up.
\How do you start the engine of a mission essential power (MEP) 806B generator? - ANS -Hold
ENGINE CONTROL switch in the START for 2 seconds.

-2.
\How often must you clean the air filter in the generator on the telescoping floodlight set when
operating under dusty conditions? - ANS -Once a day.
\On a 25-kw power distribution panel (PDP), what is the 60-amp output utilized for? - ANS -To
connect a field deployable environmental control unit (FDECU).
\The basic expeditionary airfield resources (BEAR) kitchen is powered by two generators, one
60 kW and one - ANS -30 kW.
\The Basic Expeditionary Airfield Resources Order of Battle (BOB) is based on increments on of
how many personnel? - ANS -250.

providing - ANS -120/208 VAC.
\What basic expeditionary airfield resources (BEAR) asset is used as the main distribution point
for secondary circuits? - ANS -Secondary distribution center (SDC).
\What cable size is used to connect the low-voltage mission essential power generator to the
secondary distribution center (SDC)? - ANS -25-foot, 200-amp.
\What can you do to ground the system if the ground rod cannot be driven into the earth during
deployments to locations where low voltage will be used for a short time? - ANS -Bury the
ground rod in a horizontal trench that is 18 inches deep.
