You won't find that in the code book. You can run a pipe for 20 miles if you can find conductors that long.
I was taught that in the field in the early 70's, but when I questioned it, no one could ever show me where it was in the code book.Originally posted by LarryFine:
Wasn't there a 100' limit in the past, along with the 4 x 90 rule?
I have heard this too but no one has ever been able to show it to me in the NEC.Wasn't there a 100' limit in the past, along with the 4 x 90 rule?
There's a whole chart called something like "the Georgia Tech Model" that has limits on the length on conduit that you can use for an EGC without installing an EGC. That's the only thing I've ever seen with my own two eyes that would limit conduit lengths, other than print specs.Originally posted by infinity:
