Continue with the Connections
Your generator frame or the trailer it sits on has a built-in ground terminal. Make
sure the threads on the terminal are clean down to bare metal. Test the terminal to see
if it’s tight. Also, make sure the wing nut is tight and the ground-wire lug is mated
metal-to-metal with both the generator frame or trailer and any washers in use.
On the opposite end, the ground rod must have a clamp or a thumbscrew that
connects the ground strap. If a clamp is used, make sure the area of the rod or
underground pipe that the clamp is mated to is clean, bare metal. If the area has dirt,
grease, paint or corrosion, scrape it clean.
Make sure the clamp is tight and that the strap is tight within the clamp. You might
Fnd a strap that is attached to the clamp with copper wire. That’s another temporary
measure. If it looks like it’s intended to be permanent, report it or Fx it.
Finish Well
As you wrap up your inspection of the grounding site, make sure the top of the
ground rod is below the earth’s surface. A rod sticking up from the surface could trip
someone. See if the soil around the ground rod has been treated with a mixture of salt
and water. The mixture makes the soil more conductive. Make sure every generator
has its own ground rod.

Dear Half-Mast,
Please help clear up
some confusion in our
shop. For years, we’ve
been told to fill out a
DD Form 1348-6 when
ordering parts that don’t
have NSNs on the AMDF.
We’re told to write in the
form’s REMARKS field,
“NSN not on AMDF.”
Now we hear rumors
that this process is
changing. Is a paper DD
Form 1348-6 still OK or
has it gone online only?
If it’s an electronic form
now, has the name and
number changed? Please
tell us how to handle
non-NSN requests.
SGT D.A.
Dear Sergeant D.A.,
Units should continue to use local purchase
procedures detailed in AR 710-2,
Supply
Policy Below the National Level,
and DA Pam
710-2-1,
Using Unit Supply System (Manual
Procedures),
unless otherwise instructed by
their chain of command.
Although an electronic version of DD
1348-6 is available now, the DOD MILSTRIP
administrator conFrms the form number has not
changed. You’ll still need to give the completed
form to your supply support activity accountable
ofFcer for processing.
Maybe the ever-evolving military supply
system will someday offer a way to order parts
using UPNs (universal part numbers) instead
of NSNs. Stay tuned!

Play It Safe
Never set up, adjust or fx a ground when the generator is running. I± you do, you
risk getting shocked. So play it sa±e. Make sure the generator is shut down and all
power is o±± be±ore you touch ground straps, rods, terminals, clamps or lugs. Ideally,
you should check grounds with other PMCS when the generator is o±±.
