Old voltage operated earth trip from the 1930s or 1940s.
Made by GEC, this device disconnects the supply when a voltage appears on the earth connection for an installation. They were used on installations which have a high impedance earth (usually due to an earth electrode as the only earth) to ensure disconnection when earth faults occurred.
Devices like this are no longer used, and have not been permitted in the UK since the early 1980s.
This one does not work properly, as the trip mechanism has either jammed or failed in some other way.
The book shown in the video is 'GEC Everything Electrical', dated September 1935.

Unboxing and examination of a WEP 8508D hot air station.
This item was obtained from an ebay seller and cost £40 including shipping.
The noise it makes in the video was due to one of the internal air pipes being in contact with the lid, adding a cable tie to move it slightly eliminated most of the noise.
