overlapping vs. switching neutrals
overlapping vs. switching neutrals
(OP)
In a automatic transfer switch application, the generator is a seperately dervied system at 480V. The transfer switch installed is a 4 pole with an overlapping neutral.
Questions:
1. Can an overlapping neutal be used with a separately derived system where overlapping is only momentarily (make before break)
2. What are the pros and cons of using swicthing vs. overlapping.

Or in other words when a neutral is 'switched' it is always done via overlapping neutral. This is to avoid system being left without grounding even for a moment.
