[RE-wrenches] 120% rule

Friends:

 

This new breaker looks like it incorporates some good ideas.

 

It also incorporates some pretty nauseating marketing.  The web site is all
fluff and little substance.  For example, it is not clear what brand of
panel this will fit in, listing status, etc.  I am also disgusted at the
exaggeration on the applicability of the product.  All of this makes me
hesitate to use this product.

Hi: 

I'm also not associated with the manufacturer and am not interested in
promoting the, but do get lots of questions about these kinds of things and
want to make sure I really understand what it is they are offering 

>From what I can tell it's a special dual breaker which replaces the main
panel breaker and provides contacts for the PV generated AC in such a way
that panel busbar ratings are not a factor. 

Does anyone know if that's true? 

Here's a link to a wiring layout that the manufacturer has,

I have seen a lot of talk about the meter main and solar breakers and what
the 120% rule is intended for. I have seen a product at SPI this year and as
I am not pushing this product or indorsing it, it may be of value to some of
you that are dealing with the issue of system size vs meter main check out
B3 bypass its a breaker with internal bypass built in and does not connect
in to the buss.
