Allen, I sit on the ABYC Electrical PTC where this would have happened. What
you have stated did not happen, specifications are written so that they are
overly broad in more cases that perhaps they should. You should also be aware
that all ABYC PTC meetings are open to the public, I attended three years of
them as a non member. And, if a vender wants, they can send a representative at
any time. If they cannot send a representative, they can get on the mailing
list and receive a copy of the proposed change BEFORE it is fully accepted and
"comment on it," and attend the next meeting where comments are heard and voted
on. They are allowed to speak on their comment at the meeting. There is no way
what you propose has happened, did happen. Your source of information is
flawed, and what ever manufacturer your are speaking of has had, AND STILL HAS the
opportunity to get heard. The standard is not set in stone, it is ever
changing.
A word about new technologies, THEY ARE NEW. We have begun a components PTC,
and a high voltage PTC. The components PTC came into being when the ABYC
standard did not address the possibility of digital switching off of a unibus with
taps. Why, because it was never done before, its NEW. It is now addressed. The
same is true with high voltage, it is being addressed for new drive systems.
As are new technology inverters which track multiple sources, and multiple
frequencies, and sense load requirements and automatically adjust their shore,
battery and available generators to the most efficient combination. All this is
being done in the open, not behind any closed doors. The wealth of information
brought forward at these meeting by truly gifted engineers and designers is
incredible. And the one idea that seams to be able to prevails is safe, simple,
affordable boating.
