Parallelling UPS

[karalahana]

Hello, I wonder if paralleling UPS's requires continuity of neutral all the time, ?t was said to me that with busbar feeding of n+1 ups operation caused problems (I dont know the details to much) since busbar breakers was breaking neutral of the ups'es . So I ask you if there is such a situation with parallel operation.

Switching the neutral is generally a poor idea. Unfortunately, you have not given enough information for a specific answer to your issues.
