Hi all,

I had a call out yesterday for an elderly lady wanting an outside light fitting. She clearly has no money but wanted an external plastic standard lamp she had got from somewhere installing outside in the middle of a grassed area. In short order it was clear this was going to be cost prohibitive, but cutting to the chase, it's when I made a quick inspection of the board buried deep in the back of garage full of clutter I discovered this gadget installed on the meter tails before the rest of the installation. Any ideas what this is ? (the image isn't too clear as there was hardly any light.. it's a Hagar device marked with 80Amp rating and a test button. Some sort of formative RCD ??)

The installation is currently lethal as it has no protective earth and a string if DIY cabling and terminations.. The choc block you can just see at the bottom connects an MET to the fusebox with a stranded bare bit of wire but the MET is not connected to any earth (Not PME at the head) I'd run a mile but someone is going to die if I don't get this sorted for her one way or another..
 
Have you checked the earth loop Or are you just assuming that there is no earth or earth rod installed?
 
Thanks for confirming.... obviously intended for fault protection. There was no opportunity to put the tester across anything, one of those quick calls in passing for a simple quote and took me all the time available to make a path across and through all the clutter and crap piled high in the garage to find this, but there's no obvious earth conductor. It could be the system is earthed somewhere inside but there are no earthing conductors heading out from the origin and I couldn't get access in the house itself. Scouted the whole perimeter of the building but couldn't find any evidence of a TT earth rod or conductor that might have been disconnected.
I can't get back there now before Christmas but have advised the installation needs testing to confirm it is safe.
