A gauge of the impracticality of a single-pole plug being inserted into a socket.

Purpose of the gauge manufactured in accordance with EN 50075 – Figure 4: Used for measuring and verifying the dimensions of plugs and sockets intended for household and similar applications. It is suitable for checking whether a single pin of the plug can be inserted into the socket, thereby posing an electric shock hazard. Test principle: As shown above, the gauge is placed between the pins and left undisturbed for one minute. Under its own weight, the gauge must not come into contact with the mating surfaces of the plug.
