Webb26 jan. 2024 · Usually, neutral is pegged in the middle (to minimize voltage of any wire). But on 3-phase "Delta" installations there isn't really a middle. So either a) a middle is synthesized; b) a corner is grounded making phase L1 neutral; or c) neutral is set halfway down a leg, typically in 240V "delta". 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 ... phoenix marino bath
