Copper Tie in Electrical Panel

[Marc D. Shunk]

When the red and black wire of the same multi-wire branch circuit are served by two overcurrent devices on the same leg, the current on the neutral will add. In the photographs, the red and black conductors for each multiwire branch circuit appear to land on two overcurrent devices in the same package (twin breaker). Each of these twins plug into a single buss slot. Both halves of the twin are on the same leg. If it is how I think it is, the neutrals will overload.

I'm not exactly a journalist, so I might have done a bad job of re-explaining this in layman's terms, but maybe somebody else can pick it up from here.

EDIT... nevermind.... I see they started at the bottom with a half size breaker. That puts each half of the twins on a different leg. No problem exists. Just had to get out my magnifying glass.

Thanks Marc,
I understand what your explaining, I totally missed the "twin breaker" part of it. Makes sense now, even though its not an issue in this panel.

Where is that romex coming from? It looks like it is going into the "main" compartment.
