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 ...
