How do plug locks work?
Plug locks are designed to go directly on electrical plugs. They typically encase the plug itself and can accommodate one or multiple plugs, or plugs of different sizes. Once the plug lock has been applied, it will need to be secured with a lockout tagout lock. As long as the LOTO lock is in place, it will be physically impossible for the plug to go into an electrical socket, thus cutting electrical equipment off from their power source.
