What’s Wrong Here? Hint: Palm Tree Problems

Think you know how this installation violates the NEC?

Hint: Palm tree problems.

I think this conduit body position leads to some interesting questions. Are the wiring and splices inside the LB considered “accessible” as defined in Art. 100? I say “yes.” Accessible is defined as “capable of being removed or exposed without damaging the building structure or finish or not permanently closed in or blocked by the structure, other electrical equipment, other building systems or the finish of the building.” The metal support band securing the LB to the palm tree can be removed to access the LB cover.

Section 314.29 requires boxes and conduit bodies to be installed so that wiring and devices inside of them can be rendered accessible in accordance with Sec. 314.29(A) and (B). Does either Sec. 314.29(A) or (B) even apply to boxes or conduit bodies installed on trees? I say “no.”  Section 314.29(A) applies to boxes and conduit bodies installed at the interior and exterior of buildings and other structures. A palm tree is neither a building nor a structure. Section 314.29(B) only applies to boxes and handholes installed underground. Is the wiring in this LB even required to be accessible at all? The Code may not provide a clear answer to that question so that might be a discussion you should have with your AHJ.
