Cable System Mounting
NOTE: Neutral sensor transformer mounting on cable sys-
tems can be done with brackets if desired.
A. Locate an area on the cable(s) next to an enclosure panel
as close as possible to the circuit breaker trip unit.
B. Drill or punch four 0.313 in. diameter holes in the hole
pattern (Figure 1).
C. Mount the L brackets (1) to the transformer (2) with four
#1/4-20 screws and lockwashers (3) (Figure 3).
D. Slide the transformer (2) over the cables and mount (1) to
panel (7) with 1/4-20 screws, lockwashers, and nuts (3).
NOTE Mount screws (3) in direction shown (Figure 3) to
maintain electrical spacing.
E. Connect leads from terminal X, and X2 (5) on the neutral
sensing transformer (2) using the #10-32 terminal screws
(6) provided (Figure 3).
NOTE: DO NOT use these neutral transformers with the
following circuit breakers:
