INSTALLATION
■
Sectionalizing switches are sidewall or cover-mounted
in a 1.325" diameter hole with the internal electrical
switch components completely immersed under
transformer oil or equivalent. Refer to Figure 2 for
dimensional information.
■
All parts should be inspected for damage before
using. If there is evidence of physical damage, the
unit should not be installed unless approved by your
Cooper Power Systems representative.
Step 1.
MOUNT SWITCH
■
Switch should be mounted to four (4) couplings on
inside of tank (refer to Figure 3 for coupling pattern)
before tightening locking nut to sealing gland. Failure
to do this may increase operating torque of switch or
cause damage.

■
Sealing is accomplished with O-rings on operating
shaft and gasketed sealing gland secured on outside
of tank with locking nut.
■
Switch should be located to ensure recommended
clearances in Table 4 are maintained.
TABLE 4
Recommended Clearances
Mechanical
External handle clear of obstruction. Clearances also required
for hook-stick operation.
Dielectric (Under Oil)
Minimum of 4 inches on all sides of the switch.
