GENERAL PURPOSE INDOOR
ENCLOSING CASE
This enclosing case (see Fig. 23) has a cover
through which the front part of the escutcheon (2)
extends.' (See cover illustration). The cover is
attached to the enclosing case by four mounting
screws which screw into the internally threaded
braces (1) in each corner of the enclosing case.
On the lower end of each side of the back plate
of the breaker is fastened a supporting bracket (4).
When the breaker is installed in the enclosing case,
the lower projections of this support are inserted
into slots in the inner ends of the angles (3) which
are welded to the sides of the case. The breaker
is then rocked backwards until the movable primary
disconnects (see Fig. 26) engage the stationary stud
(4) Fig. 26. Installation of the breaker is then
completed by bolting the upper part of the breaker
backplate to. the upper supporting brackets (5) on
the sides of the case•. Thus, installing the breaker
requires only the fastening of two mounting bolts
(6).
A removable steel plate in the top and bottom
of the case provides means of making any convenient
arrangement desired for the entrance and entof
line and load cables.
