Overview:
The 3 pin BS1363 plug with a lockable earth pin will be mechanically locked into its socket via the BS1363 plugs earth pin so that it cannot easily be removed from the socket.

How this works:
Once you have wired your portable appliance with the BS1363 plug with a lockable earth pin you would place the plug into any socket.

If the socket is a switched type then you can add (optional) to the plug a switch guard which easily slides over all three plug pins (neutral, line and lockable earth) and when the plug is inserted into the socket the switch is covered slightly at the bottom to stop anyone from accidentally switching off the socket. With enough force you could switch off the socket to comply with the Health and Safety at work act 1974. More information below.

When the BS1363 plug is inserted into the socket (plugged in) then you would turn the plastic disc on top of the plug clockwise with the special tool adaptor 180 degrees (half a revolution). This will lock the earth pin into the socket so that the can’t be removed without reversing the lockable action. There is a indication on the top of the plug that informs you that it is in the locked position.

Typical applications: Can be used for portable appliance equipment in hospitals where they can’t be disconnected from the socket.. Office areas so that the electrical portable appliance must not be disconnected, for example a network hub or laser printer. Use for any home products, fridge freezer, games console, TV or computer, basically any plug that you do not want to be disconnected. Show room areas or nightclubs where the public could unplug the electrical appliance. At home, if you are unfortunate to be burgled they will have to cut the wire and maybe trip out the power before they can take the item. Ideally suited for childcare facilities / crèches etc, where inquisitive little fingers may wander

Current legislation requires that in the event of emergencies, electrical flow must be able to be cut off. The design of the lockable earth pin, although preventing accidental power isolation (removing the plug), does allow purposeful isolation via the socket switch should this need arise. The switch protector if fitted is a 1 mm thick plastic reversible switch protector that slides over the three plug pins. Due to some socket designs it will not fit all types of switched sockets. If it does fit one of your sockets you will be able to switch off the socket switch, but you will have to use more force than normal to operate the switch.
