I was hooking up an Ansul system today with a shunt trip breaker. I connected the shunt trip to the normally closed contacts from the Ansul system. It seems that every time I turn on the breaker for the Ansul system, both of the pizza oven breakers trip. Should I attach to the normally open contacts? Should I wire the two pizza ovens in parallel or series? ~Peter
The Ansul system is cocked. What I mean by series/paeallel is there are two, three pole breakers, each with its' own shunt trip mechanism [takes up on breaker space]. I wired these in series instead of parallel. What I need to know is what trips the shunt trip? Is it the presence of voltage or the absence? ~Peter

One side of the shunt coils will wire to a neutral or neutral bar, (this is assuming 120 v shunt trip units) the other sides get the voltage through the Ansul switch. You will feed the Ansul common with 120 v and wire your switch leg to the open switch conductor when the Ansul system is cocked.
