On a project we are doing, a section has 347 V fluorescent lighting CCT 18,20,22. At a first glance I was going to put them on the same NEUTRAL but I quiqly changed my mind considering the harmonics in fluorescent lighting and therefore a lot of voltage on the neutral and also that these lights are not all on at the same time but they vary such as when cct 18, 20 is on cct 22 is off , and when 20,22 is on 18 is off and so on; so we dont really have a balanced load. The question is how many neutrals should I use? 2 (two) one for cct 18 and another for 20,22 or 3 Neutrals, one for each cct?
Tx for you time
