Winnie,
Thank you so much for your article. It was very helpful. I do have a better understanding now than I did before. So, basically, when I use multiwire branch circuits on a 120/240v system, I need to make sure the two ungrounded conductors are on separte phases so the neutral current will be cancelled. Can you give me examples where you would commonly use multiwire branch circuits in wiring a house? Like for instance the kitchen two small appliance branch circuits. Thanks!
