Minimum headroom

[Grouch1980]

Hey guys,
I'm looking at NEC section 110.26(A)(3) in the 2017 version, which is the height of working spaces, and it's stated as 6-1/2 feet. What if you have electrical conduits below this headroom, say at 6' AFF, in front of the panels? They are not blocking the panels. I'm assuming that's still a violation since the conduits are below 6-1/2 feet?

Sorry for the bad news but don't believe everything that you read in an article. The 1990 NEC required 6¼' of headroom {110-16(F)}. The 1993 expanded that to the current required 6½' of headroom {110.-16(F)}.

You're welcome. Something about the 6' height didn't sit right in my mind so I had to pull out a few old code books.
