Hey all,
I am working on a project that involves running a couple of GFCI protected circuits (1-15A, 1- 20A) and 3-15A switch-legs (non-GFCI) over to a carport (it is continuous to the house connected by a breezeway). The previous electricians ran the switch-legs into the crawlspace during the home renovation a couple of years ago anticipating this project (they are no longer in the picture). I am going to run UF from the house crawlspace over to the carport and into a 2" turn-up into the carport foundation. The GC had the masons install the turn-up at a depth of about 24" but only trenched out a couple of feet when the project started. The thinking was that the GC would dig the trench later and we would connect at that time. Trouble is, they trenched down and ran into the old drive way at about 16-18". We are now trying to see if I can make the connection without having to break through the old driveway...
When looking at table 300.5 I am seeing that I can't use column 4 due to the switch legs not being GFCI protected. Going to table 1, I see that for direct burial cable that if it is for "one- and two-family dwelling driveways and outdoor parking areas, and used only for dwelling-related purposes" that I can lay it in at the 18" (that we can probably get away with). The confusion is that the trench is not part of a driveway or parking area. It is just a small grassy area between the house and carport. Does this mean I have to go with the "All locations not specified below" row and bury it at 24"? Which, will mean breaking up the old drive! I'm not sure how to apply this...
Any input would be appreciated...
