!
For front connected breakers,
insulate all bare conductors
of the line side until the breaker
end. If interpole barriers are packed,
be sure to use the barriers, moreover, insulate all bare conductors by
insulating tape the like so that the tape overlaps with the barriers.
Mounting Precautions
For detailed mounting dimensions, refer to either the Loadline or
System Loadbank catalogues.
Caution
