WIRE BENDING SPACE
WIRE BENDING SPACE
(OP)
I have 3-1550 MCM cables per lug terminating in an enclosure. The '99 NEC Table 373-6b list cables in this situation up to 900 only. Cables 1000 and larger have no figures in the colum. How do I determine space required?

I believe the intent of the Code is dealing with situations where you are physically putting multiple conductors under one lug since this will require additional bending space.
For 1550 kcmil, you probably don't want to make any bends inside the enclosure, if you can avoid it.
Good luck.

Just curious as to why you would be using such large conductors? Conductors over 750kcmill are rarely cost effective.

DLO/RHW/RHH cable is a bit more flexible than building wire, but looks like 1111kcmil (2745-stand 2kV) is the upper limit.
