Installation & Adjustment Procedures
Installation & Adjustment Procedures
Preferred Switch Assembly Method
1.1.
When insulators are shipped installed on the switch, proceed to page 13 - Mounting
Disconnect Switch onto the Structure.
1.2.
Set up bases at ground level on transverse beams (base supports):
Make sure the base support beams are level, then secure the switch bases to them so
that during adjustment the switch does not tip over, The switch poles in most cases are
top heavy and easily tipped over after installing the insulators.
1.3.
Removal of live parts:
Open the blade and remove the contact end live parts assembly (see Figure 3). Now
remove the hinge end live parts assembly (see Figure 2). Rotate the insulator bearing to
the fully closed position.
Figure 2: Hinge End Figure 3: Contact End – Switch Open
1.4.
Stack insulators:
Consult your single-pole sub-assembly and control arrangement drawings for proper
positioning of levers, spacers, etc. Sort out hardware. Install and plumb the insulators,
leaving all bolts finger tight. Do not tighten. Wrench tightening of insulator bolts will be
done in Part E.
1.5.
Mount live parts on insulators:
Be sure the rotating insulator bearing (Figure 4) is in the closed position. Mount the hinge
end live parts in the closed position (Figure 2), Open the blade and mount the contact
end live parts (Figure 3). Live parts on this switch may be handled by one man. Now
tighten all bolts!
