At one time, my department did a study for PacBell to determine whether our
PBXs met the Bellcore LSRG requirements (or if not, what the problem areas
were).
Since the PBXs were not built to Bellcore requirements, ofcourse there were
differences but they bought the switches anyway, once they knew. In other
words,
the Telcos are free to negotiate any deal they want with the supplier.
Since PacBell is an RBOC (Regional Bell Operating Company) I'm not sure
what
you mean by the question about RBOC enforcement. In any event, the NEC
deems that public utilities are in a position to determine their safety
needs and the safety needs of the public using their equipment, without
overview. That view is adopted by any authority that adopts the NEC
without change (whether they knew it or not).
You mention "state" in your note. Please be aware that in some places it
is "county" regulators, in other places "city" regulators that may enforce
the National Electrical Code. When CSA was made a NRTL, they found out
that they had to get acceptance of the CSA NRTL mark in over 4500
jurisdictions in the USA.
To make this more interesting, a lot of these jurisdictions have adopted
the NEC at some time or other, but they don't update their legislation as
the NEC gets updated. That means that, BY LAW, you have to comply with
outdated versions of the NEC in any number of jurisdictions.
In short, the US electrical safety system, from a jurisprudence
perpsective, is a dog's breakfast. As a supplier, you can do only so much
and given the lack of corpses in the streets, that seems to be enough.
An interesting question that will be asked, particularly now that the EU is
doing alright with a Supplier's Declaration of Conformity, is there a
justification for the North American regime ? Probably not, but before you
have changed the statutes in all those jurisdictions, we'll all be buried.
Just think of how many "TREGGERS" it supplies with a living.
Long Live Redundancy.
