I'd not do it. While it may last 100 years, it may be a problem in

not the common "workman like manner" to have a wire. If the
next owner decides to replace the door, he may chop or cut into the
threshold and cut the wire as it is not expected to be there. It may
even be you once senility sets in.

Couldn't you put up one of those little signs that says: "Underground
utilities. Buried cable." on the door jamb?



Edwin has hit on my thinking...

If it isn't the only way to route the cable for other reasons than the
initial want to save a few pennies, I'd vote for "No" for those reasons.

_IF_ (the proverbial big if which I think has already been ruled out
here) it were the only rational way across the doorway, and I were
confronted w/ the problem I don't believe I would simply lay the cable
under an Al (I presume) threshold but would make a cable channel in the
sill plate or subflooring and protect that per Code for nailing into by
a metal plate over it (not that I'm recommending doing that or
anything... )...
