[RE-wrenches] Utility Dis-connect

Here in NY, the State Public Service Commission is proposing the lockable AC
disconnect requirement be removed for systems below 15kW.
This from a recently circulated New York State Standard Interconnection
Requirements proposal:

4.	The use of external disconnect switch has proven to be redundant and
unnecessary in small residential systems using inverters that meet relevant
Underwriters Laboratories (UL) and Institute of Electrical and Electronics
Engineers (IEEE) standards.  Therefore, Staff proposes to eliminate the
external disconnect switch requirements for systems 15 kW or less that meet
UL 1741 (November 2005 revision).


There may be hope yet!

I know installing the totally useless exterior lock-able dis-connect has
been a bone of contention for us all, but was a necessary evil to get many
utilities to sign onto net metering in their state back in the late 90's.
However, now that we have had a few years of showing these are never used,
are not needed, linemen would not know if there were in their work area, and
are a waste of money, has there been any states or utilities that are giving
up on this requirement?

If not, any interest in trying to make this requirement go away?
