Re: Bundled = Derated
iwire: are you saying that in mass. you cannot run more than three romex in a hole irregardless of derating? Derating allows up to 10 cables as ".." said before the derating affects the circuit overcurrent protection, or load, at least for the smaller romex.
I find that kind of odd, since they allow unprotected SE to run into a house. Here in CA, which does not care about consistency either, it is the opposite, generally. SF is its own world and to some extent rightly so; old, old wood common wall structures with ancient wiring, any new stuff is generally strict. They pretty much burned down once.
