One of our installers put a shovel through a length of romex underground
today? Not even direct burial wire!

Agreed with Dick on this one. First, if you are going the DB route, then you
have to get it down at least 24" instead of 18". No problem some places, a
HUGE problem others. Then there are the burrowing critters like ground
squirrels which love to chew on anything. I have heard that there is som
The insulation on Al cable rated for direct burial is thick and tough. But,
DON'T direct bury it. Carefully pull it into correctly installed PVC conduit.
Use marker tape above the conduit, just below grade.
If you're in an area that doesn't experience ground frost, MAYBE, VERY
CAREFULLY, plant the
Aluminum wire got its bad name during the era when it was use in 15
and 20 amp circuits, with #12 and #10 wire. That stuff is a
nightmare. As an electrician that has cleaned up some of the messes,
I can supply ample horror stories.
#2 and larger sizes of AL work fine. It is important to use
I have used AL wire in DC circuits for 30 years and have never had a problem.
If you carefully follow the protocols for working with AL you should have the
same experience. As pointed out the cost difference can be staggering. I'm

Thanks for the input. Excuse me please, "OG jobs" are?
If the wire had been copper and didn't melt, but instead continued to arc,
would the resultant heat have eventually started a fire?
What type of splice was it?
Does no one else use Al for DC? Here in rocky Vermont/NH,
we use the same
The problem with Al is that, IF there is ever a loose
connection, & associated arcing, that it melts not like
copper in the same situation which may arc but not melt.
I have come in on OG jobs where Al was employed and found J
boxes that were [sometimes wet] and had loose connections
and the splic
