Help straighten me out on this. While talking to someone in another forum, we seemed to disagree on MW branch circuits. He says that the ungrounded conductors in this circuit shall have a disconnecting means that will disconnect the circuits simultaniously at their panel of origin.
I say, that only applies to multiwire cicuits that attach to a device on the same yoke. Say a split duplex where each the top and bottom outlet is fed with a different circuit. Those types of installations require a multipole breaker to turn off both circuits. I also say, in a regular MW branch circuit setup, where each circuit takes care of it's own set of devices while each share a common neutral, that you do not have to have a single way to disconnect the circuits simultaniously. I think I'm right about this, but he cited Section 210.4
I even have a video, Mike Holt
