Bill:
Why is it necessary that the sub have a main breaker?

>As long as the subpanel has a main breaker, rather than a main lug panel, it

>Friends:

>I had just asked the question referred to below and received your gracious
>answers when I was called out today to look at installation of a 30KW
>residential system. This translates to over 100 AAC. The meter main is a
>CH HP404040SHA,
>(http://www.ch.cutler-hammer.com/unsecure/cms1/TB00500001E.PDF page 73) a
>400 amp meter main combo with two 200 A main breakers. One feeds a 200 A
>buss and one feeds a remote sub panel.
>
>There is no combination that allows me to feed 125 A into the 200 A
>buss. The inverter current, rated up for continuous duty is 170.45 (at 220
>VAC). The buss rating times 1.2 is 240. This allows me a 70 A breaker
>which won't even handle the PV generation current.
>
>I'm not sure I can tap the conductors between the meter socket and the buss
>bars, they are very short, bent into a curve and they are part of a listed
>assembly.
>
>Wait, I think I just now got the answer! There will be a 200 A feeder from
>the second main to a sub-panel. How about if I tap the conductors going to
>the sub? This way I'm not feeding a buss and I don't have to tap between
>the meter and the buss. Any comments?
