There are several devices on the market for locking an electrical plug. But why would you need to lock an electrical plug?
Well there are a few reasons. Let’s look at them in turn and illustrate the different plug locking devices.
You might have a portable hand tool, for example power drill, circular saw or jack-hammer that you want to prevent people from using due to on-going maintenance activities either with the device itself or the environment in which the hand tool is being used. In these cases, locking the connection plug away in a plug lockout can render the tool inoperable.
Alternatively, the hand tool or electrical appliance may have failed a PAT test and is awaiting repair. This is another reason for locking the plug to prevent the equipment from being used.
You can also lock electrical sockets. An example of this application could be refrigeration equipment in a kitchen, hospital or laboratory. Imagine the cleaner comes in looking for somewhere the plug in their vacuum cleaner, unplugs the fridge and forgets to reconnect. This could have very serious consequences. A socket lock could be the ideal solution to prevent this from happening. There are two different types of socket lock. The first version is a large bright red device that alerts the person who is preparing to remove the plug. The second version actually locks the plug in the socket and can only be removed with a permit key. See the images below.
To conclude, if electrical disconnection or reconnection must be prevented, there are several product solutions available to solve this problem.
