Installation

Attaching Couplings to 

Outboard Bearings

Use the following steps to attach couplings to 
the outboard bearings:

Step 4

Attach pipe coupling(s) to the outboard bearing 
assembly (or assemblies) in accordance with 
the item numbers specified on the erection 
drawing.

Attach a pipe-to-hexagon type universal cou-

pling to the hexagonal shaft on the underside of 
the outboard bearing assembly. See Figure 6 as 
well as Detail A-A on the erection drawing. This 
coupling is used in Step 9 to attach the upper 
section of vertical operating pipe. 

For triangular-upright and tiered-

upright switch mounting configurations:

 

Attach additional pipe-to-hexagon type 
universal couplings that will be used to 
connect the outboard bearing assemblies. 
 

For mounting configurations using an out-
board bearing assembly mounted between 
switch poles:

 The outboard bearing connects 

to the interphase pipe with a drag link (flat-bar 
or pipe type) and an offset coupling. See Detail 
A on the erection drawing. Attach one end of 
the drag link to the outboard bearing crank-
arm, then attach the offset coupling to the 
other end of the drag link. See Figures 7 and 8. 

Installing the Switch to the 

Mounting Structure

Use the following steps to install the switch to 
the mounting structure:

Step 5

 

WARNING

DO NOT lift the switch pole-units by rigging 
on the “live parts” or subject these parts to 
undue stress from slings or fall lines . 
Lifting the pole-units by the live parts will 
damage the switch . Rough handling may 
cause damage to the blades, contacts, and/
or interrupters .
Failure to lift the pole-units properly can result 
in switch damage, causing improper opera-
tion, arcing, or electrical shock .
