See 2002 NEC 310.4 (1)
No tolerances given.

Exactly the problem. [Linked Image]

What tolerance is acceptable, 1", 1/2", .00025"?

It is imposable for one conductor to be exactly the same length as another, there has to be a tolerance.

And to say one specific tolerance applies makes no sense. It would make more sense to say the tolerance is a certain percentage of the total length.


Anyway thats my two cents. [Linked Image]
