54.4-C7)    New Rule

Strikeout and Underline Version

Rule 54.4-C7

54.4-C7)    Vertically at Crossings in Spans:

The Vertical clearance required at crossings in spans by Table 2, Cases 4, 5, 6 and 7, may be reduced when:

1)    All conductors are of the same circuit, and

2)    Vertical taps are installed between related crossing conductors.

The minimum vertical clearance shall be the following:

EXCEPTIONS:

a)    In vertical configuration, there is no specific vertical clearance required between conductors that are mechanically and electrically connected at the crossing.

b)    There is no specific clearance required for 0 - 750 volt multiconductor cable having a bare neutral (Rule 54.10 ) provided the messengers are mechanically connected.
