3-30 Log #2256 NEC-P03 Final Action: Reject
(300.5(D)(3))
____________________________________________________________
Submitter: Donald A. Ganiere, Ottawa, IL
Comment on Proposal No: 3-49
Recommendation: The panel should accept this proposal.
Substantiation: The panel statement says that if a safety rule is difficult or
expensive to comply with then we don’t need it in the code. The “warning
ribbon” rule is intended to provide some protection in the form of a warning
ribbon to someone who is digging in the area of the underground service cable.
The method of original installation does not change the level of hazard to
the future digger. They are just as hurt or killed if they dig into an energized
service cable that was installed using directional boring equipment as one that
was installed using conventional trenching. If this is really a hazard to future
workers, then they deserve the protection of a warning ribbon no matter what
cable installation method was used. If it is not really a hazard, then the rule
should be deleted from the code, but you can’t have it both ways. The panel
statement says one is safe to the future digger and the other is a hazard, when
in reality there is no difference in the level of hazard involved.
Panel Meeting Action: Reject
Panel Statement: The only way to install a warning ribbon 12 inches above a
bored hole containing service conductors would be to drill an additional hole
with the ribbon inserted in the hole and pulled through from one location to
another or to dig a trench to a depth 12 inches above the cable. In addition,
since the ribbon would be installed in a drilled hole, the inspector would not
be able to verify the depth of the ribbon as being 12 inches above the service
conductors. Unenforceable requirements must not be inserted into the NEC.
