&gt; You seem to be doubting the feasibility of micro grids, but people are already doing this with 240 V.<p>Not doubting them at all. It&#x27;s just that I have some experience with burying high current &#x2F; high voltage cabling and keeping such installations safe.<p>&gt; Granted, it&#x27;s harder to steal copper wire that is at 240 V.<p>Just use VMVK, armored version if you can get it. I got a whole pile of it that was left over after a large construction job on a dam in Canada. Paid pennies on the dollar, basically I just paid the copper market price.
