From opposite sides they cancel out. In addition under NEC 2008 you have to use a 240v breaker for a MWBC, so sharing across the same buss is not possible. E.

If I have single pole breakers and I know I'm sharing neutrals, then I want to specify commas as a circuit separator.
Webb9 okt. 2012 · So to cure. 1) Return to one MCB for all lights. With the new low power lights likely it no longer needs the extra power. But do remember ONE MCB not two MCB's from the same RCD although the latter works it's still against the rules. 2) Swap the strapper to a three core cable. 3) Remove the two way lighting.

WebbIf two separate circuits fed from separate supply lines share a neutral, the main danger is when the neutral becomes disconnected. If this happens, voltage will dramatically … WebbThe reason sharing a neutral works is because the current for all three circuits should be 120 degrees out of phase from each other. When your current wave form becomes distorted from harmonics, the currents from the different circuits can become in phase with each other on the neutral. This causes the neutral to overheat and distort the line ...
