UF Exposure Question

I'm wiring a small well house (8ftx8ft). It consist of a simple 12/2 circuit (one switch, one light & once GFCI recept). This is a branch circuit that originates from a panel in my nearby shop (UF-B underground wiring). I used UF-B for all of the wiring inside the well house. The county code enforcement references NEC 2014 as their adopted electrical code. I had my inspection today but I was not present during it. The notice that was left had a note that stated"wiring 6ft or less must be covered or in conduit per NEC". I have a copy of NEC 2011 that I have reviewed. I did not see a reference tied to a specific branch length. I assume he may have meant 6 Ft or more? From what I have found thus far, it would appear that NMC (or UF) can be exposed if not subject to damage. The wiring is centered on the studs and secured in place with insulated staples. I would take that to be safe from danger.

Description of Installation:
One 12/2 UF-B and one 10/2 UF-B emerge from grade in 1" PVC conduit and enter into the well house wall via an LB fitting. The 10/2 is routed to a disconnect with in 30" of LB. The 12/2 is routed to a double gang box (1 switch and one recep...just shy of 6 ft total run) and then up to a single light (more than 6 ft run).

I did not get a chance to call the inspector before the office closed since I got home after hours to find his note. I just wanted some feedback on his 6 ft comment given I have not found a reference to that in the 2011 NEC. Thought it may be something new in 2014? I have seen longer exposed runs of UF-B before on outside applications so I was a little surprised. I have no issue using a piece of conduit if that is what satisfies the local code. I realize that local code governs. I can put in a metal gang box and use flex conduit or MC. I see that MC appears to be limited to 6ft on lighting branches now so that would mean adding a junction box in that run. Not a problem since I may wish to add an outside light later on anyway.

Just trying to be informed.....


Just looking for some feedback before I make the call Monday.

The inspector gets to decide if the wiring is exposed to damage, not the installer.

Many areas have standard rules of thumb or even written amendments stating all exposed NM or UF below a certain height is subject to damage.

With that said I am closing this thread, in accordance with the Forum Rules.
