Step-by-Step Guide to Installing the LS14008 Switch

The LS14008 Cole Hersee switch is built for heavy-duty use. This guide shows how to install it safely and correctly—from setup to testing—to ensure reliable performance and prevent faults.

1. Step-by-Step Guide to
Installing the LS14008 Switch
The LS14008 switch is installed by isolating power, preparing tools and
mounting surface, securely fitting the O-ring–sealed switch, connecting
and torquing conductors to spec, testing insulation and operation, and
ensuring proper sealing and safety compliance.
Key Specifications
Current ratings: 2000 A intermittent / 300 A
continuous
Mounting: 19 mm hole, 75 mm × 125 mm
dimensions
Weight: 0.55 kg
Terminals: Two 12.5 mm main + two 4.5 mm
field
Protection: O-ring sealed housing for weather
resistance
TOOLS & PREPARATION
Gather required tools (torque wrench,
drill, screwdrivers, ratchet set, cable lugs).
Wear PPE — insulated gloves, safety
glasses, lockout/tagout devices
Isolate power and verify system is de-
energised
Apply lockout tags to prevent accidental
energisation
Mark mounting holes, drill and deburr for
clean edges
Position so O-ring seal sits flush on the
surface
Install bolts, washers, and nuts evenly to
prevent distortion
Tighten to specified torque — avoid
overtightening
Check handle clearance for smooth
rotation
Ensure visibility and accessibility for
future servicing
WIRING & ELECTRICAL
CONNECTIONS
Prepare conductors with crimped lugs (12.5
mm / 4.5 mm terminals)
Connect main conductors to large
terminals, field wires to small
Route cables neatly with no sharp bends or
tension
Fit insulating boots for moisture and dust
protection
Torque bolts to spec and test insulation
resistance
MOUNTING THE SWITCH
Testing & Commissioning
Perform continuity tests (on/off) while de-
energised
Confirm loads remain isolated when switch
is off
Re-energise and cycle under load to test
function
Attach labels and isolation tags per site
standards
Record results in site isolation log
