I watched the video. the afci and gfci breakers have a feature so that when they reach 'end of life', they lock out and have to be replaced. I wonder how long end of life is: 10 years, 15, 20 trips? I dunno that I'd like that both hots and neutral wires terminate on blocks instead of the breakers; seems like twice as many connections to fail, and more likely a HO could swap a tripping breaker out with a higher amperage one much easier since no wiring has to be undone or moved. also seems like it might limit where higher amperage breakers could go unless those blocks can accept #1-#14 wire
Those concerns aside, they do look pretty sleek and no doubt will be appearing in installations soon. cost would have to be inline with other panels or they wont sell.
Heh, you beat me to it by a minute.
