Can anyone interpret column 4 as to be applied to a "garden style"(non-high rise) apartment complex, and allow a 120-volt, 20-amp GFCI protected UF cable to be buried @ 12"? Apartments ARE residences, and no mention is made regarding single or multi-family residences, except in the left column pertaining to driveways and parking areas. But I think the intent of column 4 is directed at single homes and not multi-family dwellings.
Exhibit 300.6 ('02 Handbook) depicts a single home, but it addresses cable installed under a driveway.
Redsy, the more I think about it, it shouldn't be used is this situation, because the circuit doesn't orginate from the residence in question. This circuit would be from the house load panel, and this in my mind would not be considered "residential"...
Any one see it this way?

I guess you could use some judgement and look at the use of the dirt in question. If this was going through areas that are used like a typical back yard, col 4 probably applies. If this is some common area that gets used like a commercial site, park or playground it would be col 1. It is certainly column 1 if this is going through a flower bed maintained by the landscape guys. I might even "suggest" pipe in there.
