How deeply are power lines that run to a house from a ground-level
transformer actually buried?  I am going to be putting in a fence
across where there is a such line and I was about to call the "Call us
before you dig" number but their web site says that they only need to
be called if I am digging deeper than 24 inches.  I am just driving in
normal steel T posts which are probably less than a foot deep into the
ground but I am still a bit nervous.
