2.2 CON EDISON INITIAL ENTRY AND VISUAL INSPECTION
Once the structure is initially entered, a visual inspection shall be conducted for exposed live conductors, improperly sealed cable ends, visual burnouts, structural damage, D-Fault tags, environmental tags, and cable ends cut excessively long where the cable-end could contact the structure cover/grating or metal frame.
The visual inspection shall be documented.
In addition, abnormalities, such as oil or compound leaking from cable or joints, broken cable sheaths or joint sleeves, hot localized surface tempera- tures of cables or joints, or joints that are swollen be- yond normal tolerance are presumed to lead to or to be an indication of an impending fault. These abnor- malities are referred to as “D-Faults.”
EO-1184, Identifying Cable and Splice Abnormalities On Distribution Feeders, shall be followed to deter- mine when a cable must be de- energized for work in a manhole.
If a D-Fault is noted, it must be reported and the structure shall be exited immediately. If a D-Fault tag, environmental tag, or any unsafe condition is found further steps shall only be taken with consent and advice of the control center and/or field supervi- sor.
Cable inspections are not required for enclosed spaces where electrical equipment has not been pre- viously tied into the system, or for service boxes with no primary cable.
