[sdiy] 0.100 pin header reliability.

Maybe it differs across the US, here in the South I've never seen
anything but AL from the pole to the house.

The two big issues with AL is that you have to bump up in size for the
same current (12 AWG AL for the load carrying of 14 AWG CU) and that
if you splice to copper you must add a compound to control oxidation
(creep as well) The problem came from using copper
receptacles/switches with AL wire. Given the ever upward price of
copper, I think we'll see it used to wire houses again in the near
future.
