I've heard a vicious rumor that the 2008 NEC is going to expand the number of locations that AFCI will be required in residential work.
Is this just an evil rumor or is this "the beginning of the end" for shared neutrals?

Surely everyone by now knows that there are two pole AFCI breakers, just as there are two pole GFCI breakers!

The proposal was accepted, they are just haggling about the exceptions

No, earlydean, I didn't know that. The last I heard, the two-pole AFCI existed only in some manufacturers' fantasy, and had not yet made it into the supply chain.

The AFCI issue is likely to become even more contentious than it has been so far, as differing technologies, and codes, conflict.

Buy APC stock. There is going to be a surge in the UPS business.

Note that this is only the ROP, I expect that there will be a lot of comments and the ROP could be reversed in the ROC.

The other one that HAS to get amended is the universal requirement for tamper proof receptacles in dwellings.
That would add a few buck to a house wouldn't it. No more 43 cent receptacles, they would be more like $8 a pop.

I for one would be very happy if shared neutrals died a fast and painful death!!

However, this whole AFCI requirement is a huge joke. You have devices that are still prone to nuisance trips, which invite Joe Homeowner to take a trip (pun intended) to the big box and get a bigger breaker to put in the panel (and we've all seen that too many idiots know just enough to change a breaker) because JH isn't bright enough to know why the breaker keeps tripping.

GFCI's, having been throughly developed are however a great idea. Yeah, I know they have different goals, but ...

Oh, yeah, that reminds me..AFCI's also have GFI circuits too, right? Then how do you know WHY it tripped? As some of you have already posted, AFCI problems are a real bear to troubleshoot!!

Don't even say that as a joke!! You know someone will get the bright idea to submit that!!

I haven't purchased a two-pole AFCI yet, but I recall handling one at a trade show. The homes I have wired only required one each, and I don't usually use multiwire branch circuits for residential anyway.
Haven't they started selling them yet?

No way, never.

12/4 Cable and I are to good friends for us to part company.

Besides it makes no sense electrically to do away with MWBCs.

Once the branch circuits reach the panel it is common neutral all the way back to the source. The neutral bar is no better or worse than a wire nut. There is nothing in an electrical panel that makes a common neutral 'bad' on the load side and 'good' on the line side.

About all we can say is possible harmonic loads on the neutral but that will happen to the feeder neutral as well.

Running all two wire circuits is wasteful of resources and give us greater voltage drop issues.
