Please provide the cite for that. And explain why if
it's not permitted, why major panel manufacturers have listed
lockout slides for their panels, for exactly the purpose I
outlined?


The sad thing is that those plates and about 3 screws and nuts cost from
about $ 50 to $ 100. Should be less than $ 20 for what it cost to make
them.


Yes, but, they are soooooo nice. I built a house 5 years ago and they
put in an emergency panel. So, only a select set of breakers get
powered from the generator. This is ok, but I wish I had remembered the
mechanical interlock thing, when building. Here's a link to one of
them: http://www.interlockkit.com/ Yes they are overpriced for what
you get, but, especially on a retrofit, it is much easier and cheaper
than the alternative.
