Does 310-15.b Change in 2011

[Buck Parrish]

I was wondering as in 08 , the part about "If you feed a 200 amp sericve indoors" (via a meter base combo, 200 amp feed through panel) .
Then feed an AC off the outside panel. The conductors to the 200 amp panel inside have to be bigger then the mast service entrance conductors to the inside panel.
Has this changed in 2011?
Any body know?

Right now it's a draft, there were issues on when table 310.16 ampacities were to be used instead of the residential allowance for type SE cable and they came up with the first feeder only then after that if you use SER its protected down to 90 amps. For years everyone was just putting a 100 on them until someone somewhere picked up on it.

Good thanks, Looks like it changed back.
And I noticed #2 AL is good for 100 amps :grin:
Great News
I knew they would come around...

Now, if we can just convince Virginia to skip the '08.
