When installing a SN1200NACT into a NA1200AWK, is there a correct direction to mount it, since it is symmetrical and can mount either of two directions?

The H2 markings on the neutral CT should be toward the top of the enclosure, with the H1, X1 and X2 markings on the neutral CT toward the bottom of the enclosure. If the incoming feed wires are going into the ON side of the NXL breaker, then the feed neutral wires go into the top neutral terminals, nearest the neutral CT H2 marking. If the feed wires are going into the OFF side of the NX breaker, then the feed neutral wires go into the bottom neutral terminals, nearest the neutral CT H1 marking. If it is miswired and causing nuisance tripping, the solution is to switch the secondary wires at terminals X1 and X2.
