Jeff and All,
My experience with Pacific Gas & Electric (PG&E) here in CA is that
they require a visible handle, non-fused, lockable disconnect. Since
we're on the ac output of the inverter, that's a pretty standard 30A
or 60A box. Even in Nema 3R, it's about $60.00 wholesale. Installed
in most systems it adds less than $200.00 retail to the total cost of
the system. While I agree that it is unnecessary with today's
inverters, the only rationale I've heard expressed that makes any
sense is that it gives a lineman 1) a visual indication of OFF and 2)
peace of mind once they lock it out for line work.
It's important to keep in mind that most utility lineman would NOT
qualify for an electrician's license in most states. I'm not
"dissing" them in any way, it's just that their work experience is
limited by what they do. Given that, I don't have a problem with
making their stress level just a little less. There are bigger, more
important fights to fight.
