Installation
Operating Pipe Preparation
If desired, the vertical operating pipe can be cut to length
(if not precut at the factory) before proceeding to the job
site. The standard lengths of pipe supplied measure 6 feet
10 inches (208 cm). Cutting dimensions are shown on the
erection drawing.
Mounting to Wood
When mounting the switch and its operating mechanism
to a wood pole, S&C recommends suitably sized square
washers be placed under the nuts. S&C also recommends
using spring-type washers between the square washers
and nuts to compensate for wood-pole shrinkage and
thus maintain fastener tightness. Square and spring-type
washers are not included with the switch.
STEP 1. Drill two -inch diameter holes in the utility
pole at the desired height for mounting the
switch. Refer to the erection drawing for details.
STEP 2. Insert two ⅝-inch diameter through-bolts (not
furnished) in the holes drilled in Step 1 and
secure loosely with the necessary square
washers and nuts so the heads of the bolts
project sufciently from the face of the pole to
engage the switch-base mounting bracket.
Make sure the at washer for each bolt is
between the bolt head and the switch-base pole-
mounting bracket.
