Sync check
Sync check
(OP)
Is there a simple applications guide for a sync check relay configuration? A SWBD with two mains (open transition) doesn't seem complicated, but I can seem to explain the circuitry connections needed to a local panel builder. A diagram or picture is worth a thousand words.

Sorry, you are correct. I meant closed tranition. It will be with two manually operated breakers.
I checked with Basler and their BE1-25, but they don't have an applications guide that shows the two relays and the related sequence of operation (dead bus, live bus, etc).

If your alternate main is from a non utility source you will need it
Closed transition does open a can of worms in regards to protection, co-ordination, arc flash studies, and available fault current.
