Place the circuit breaker in the OFF position
Place the Lockout device over the switch.
Tighten the set screw securely
with a 1/8” or smaller flathead
screwdriver. Typically, two (2) complete revolutions of the setscrew
are required after the screw first touches the switch. Do not over
tighten the setscrew. The circuit breaker switch may fracture.
Verify that the Lockout is adequately secured to the switch.
Insert a padlock through both holes. This will prevent access to the
setscrew. The Lockout device is designed for use with 9/32” diameter
shackle padlocks. Smaller diameter padlocks may not adequately
block access to the setscrew.
Verify that the circuit breaker switch cannot be repositioned to ON.
Attach a safety tag.
