Bending Radius

300.12, et al, talks an aweful lot about bending "space" but I don't read anything about bend radius or how that bending space may or may not be used. If the space is there, but you bend the conductor tighter than the space, seems like you're still good. No?

However IMO Table 312.6(B) does apply to the conductors and will likely prohibit 4/0 from entering the back of a meter socket just as it often prohibits 4/0 from entering the back of a typical residential panel.

4/0 with one wire per terminal needs 7" of bending space, if it's a lay in lug like a meter socket often is you can reduce the 7" down to 6"

Bob, table 312.6a applies to conductors not leaving the oppisite wall. In that table only 4" are required for the bending radius to the can.
(1) Conductors Not Entering or Leaving Opposite Wall. Table 312.6(A) shall apply where the conductor does not enter or leave the enclosure through the wall opposite its terminal.

Note: Bending space at terminals shall be measured in a straight line from the end of the lug or wire connector (in the direction that the wire leaves the terminal) to the wall, barrier, or obstruction.

Yes and no.

You're still good until you bend the conductor sharper than mfgr spec's permit, i.e. if the minimum bending space is the larger of the two spec's :)

Yes, it has been clearly established I was wrong. :grin:

Sorry about that.
