30 Ampere and 60 Ampere Size Installation
Mounting the
1. Measure the cabinet depth (Dimension “J” on Page 2 ), to insure that
Disconnect Switch
your cabinet is within the minimum and maximum size range.
2. Select desired location on disconnect switch mounting surface for
mounting the disconnect switch.
3. From the line drawing and dimension table on Page 2 , locate the
mounting holes of the switch.
4. Mount the disconnect switch on the enclosure mounting surface. Use
3/16" or #10 screw. Torque to 25-30 lb-in.
Mounting the 1. Determine shaft length (Dimension “L” on Page 2 ) from table and cut
Activating Rod
uninsulated end of shaft to size.
2. Insert the insulated end of shaft through the hole in the support
bracket and into the two square holes in the switch lever. Torque the
set screw to 35-40lb-in to secure shaft to switch lever. Insert hitch pin
furnished into hole in shaft (see side view on Page 2 ).
3. Determine the adjusted coupling position (Dimension “K” on Page 2 )
and attach the coupling to the shaft with set screws. The “D” molded
on the face of the coupling must be at the bottom and the “C” at the top,
with the switch in "Off" position. Torque the set screws to 25-30 lb-in.
Mounting the 1. Using the template and dimension table as a guide, determine the
Handle Assembly
point on the cover, within 1/8", at which the center of the rod and the
center of the handle assembly should meet.
2. With the template located, center-punch the location of the five
mounting holes. Drill the 13/64" diameter holes. Drill pilot holes for
Greenlee cutters for the
1
/2 " and 1
1
/4 " diameter holes. Cut the
1
/2 " diameter
hole with Greenlee cutter first, then the 1
1
/4 " diameter hole.
3. Close the cover and check the coupling spear-point for alignment with
the center of the large diameter hole. Adjust the support bracket, if
necessary, to center the spear-point within 1/16".
4. On the outside surface of the cover, mount the nameplate and handle
so that the handle passes through the nameplate and enclosure cover.
Peel off the adhesive protective shield from the back of the nameplate
before installing. On the inside surface of the cover the rubber washer,
the spacer (used only on 14 and 16 gauge covers) and the interlock are
assembled, in that order, around the protruding shoulder of the handle
assembly. Torque the three mounting screws to 16-20 lb-in.
5.
CAUTION:
Make sure the cover interlock latch swings freely.
6. With the handle in the “Open” position, the cover should open freely.
With the handle in either the “On”, “Off” or “Lock” position, the cover
interlock MUST prevent opening the cover unless the defeater is used.
