Overhead service conductors

[PhoenixBob]

2005 NEC requires 8' clearance above roof surfaces. Does this meet the definition of roof surface? It is an aluminum patio cover with 2" spacing between the lattice members.

Re: Overhead service conductors

Looking at 230.24(A) exception #3. Question can one walk out on that system? So that last sentence in that exception states not more than 6' of conductors are permitted to pass over this roof......However, can one actually define this trellis as a roof?

Thats the big question.

Re: Overhead service conductors

I doubt that someone would be able to walk on that "roof" surface. The code doesn't specify it, but isn't that the intent, proximity to the conductors? I wouldn't have any heartburn on it. JMHO

If that was a "roof" then it would have to be a minimum Class C "roof" wouldn't it? (what if the lattice was wood?)
