Any ideas? How deep do 110 volt wires need to be buried?


24" in open areas, it can be less if it goes under concrete, etc.


Let me correct that. I just looked at the code to make sure
and above is true for direct burial cable. If you use pvc
conduit, it's 18". And there is an exception for branch circuits
of 20A or less that are GFCI protected, in which case it's 12"
regardless if it's direct burial or conduit.
