I'd like someone to explain it to me, too. But all my experience so far bears out the use of shared neuts has been nothing but trouble. Even when the workmanship and all connections are good.

And all my experience tells me otherwise. [Linked Image]

I work for a very large EC, the past 6 years in the division that handles warranty issues and I see no difference in the frequency of repairs between two wire and MWBCs.

But lets think about that, both of us have biases and neither of us did any real testing or logging.

In other words our experience means little. [Linked Image]

I am not picking a fight, I agree with Roger if you do not like MWBCs do not use them. I will continue to use them.

Many of the building we do are quite large, MWBCs help greatly to overcome voltage drop.
