This topic came up at class last night, and our instructor sent the issue home with us to research so we can resolve it next class. We were doing some basic wire fill calculations for auxiliary gutter... I was looking that section up in the NEC index and also noticed articles for wireways. I read the definitions of each and understand the difference in application.. but at the shop today I found a piece of gutter that still had a sticker on it; it said something like "suitable for use as auxiliary gutter or wireway."
So I assume they're roughly the same thing.. but that leads me to wonder, is there some product out there that is suitable as ONLY auxiliary gutter or ONLY wireway? What is the difference, other than application? And why does the code make it two different things when they're so similar?
I read this thread also, but am still not entirely clear on the issue: http://forums.mikeholt.com/showthread.php?t=110309&highlight=wireway+auxiliary+gutter
P.S. Anyone know why gutter fill is normally 20% but can be 50% in an elevator-type application?
