Switch Handle Lock - Terasaki Isolator Handles

Both units installed relatively easily per the instructions. Both worked correctly with no problems. I suspect that demand for these devices will increase as Lockout Tagout programs evolve in industry. For us, we have found a few instances when the breaker or disconnect did not open even though the outside handle was showing in the disconnect position. This led to a policy change where an electrician must come behind the operator to “meter check” that the breaker or switch did actually open. That extra step can add a lot of time to otherwise routine maintenance jobs. The DeadEasy removes the need for an electrician and the associated delay. We will probably be purchasing more in the future.
