This is underneath the stairs cupboard. After a quick Google of the details on the plug, it appears to be Lectros Damp Proofing system. (https://www.ebay.co.uk/itm/LECTROS-...LUG-ELECTRO-OSMOSIS-OSMOTIC-DPC-/130567177153) Where in the property would this equipment be servicing? I note the green LED on the front is not illuminated. I could really do with removing this for a few moment to put in a 3way plug extension, as I wish to feed a lamp on the outside of the cupboard for the hallway. Can anyone advise me more about this equipment, if it's in use, and if it can perhaps be removed? I have used a electricity testing pen, and it did not pick up any live around the plug.
