If a fault in a floodlight
energizes its metal parts—and you touch
it—
Yoweeeee!
CECOM and Tobyhanna Army Depot have come
up with a fix and your power generator maintainer
can, and should, apply it.
Here’s what your generator expert should do:
1.
Disconnect the floodlight power cable from the
generator set and fully retract the telescopic mast.
2.
Each telescoping mast, NSN 6230-00-386-
8939, needs two 3-ft lengths and one
155-ft length of #8 AWG green
grounding wire, NSN 6145-
01-131-3818.
3.
With
the flood-
lights, NSN 6230-
00-299-7072, mounted
on the mast, install one 3-ft
grounding wire between the #3
and #2 (central-most) floodlights by
connecting the wire to the floodlight
mounting bracket bolts.
4. Now install the remaining 3-ft grounding wire
between the #2 and #1 floodlight.
5. Finally, connect the 155-ft grounding wire to the mount-
ing bracket bolt of the #1 floodlight. Thread the grounding
wire down the telescoping mast in parallel to the power
cable.
Use tie wraps, NSN 5975-00-074-2072, to secure the
grounding wire to the power cable. Connect the other end
of the grounding wire to the power generator ground lug.
