My brother had some weird stuff going on when he bought a new house…the previous home owners had “some” free unmetered power they would use.
I’m not saying that’s your case…it could be the opposite IDK
So your sending power to it after it’s metered? if that’s the case, that doesn’t sound good
Was there ever solar panels or a wind generator on the building? Or a steam boiler system? If so maybe the previous owners sold power back to the power company. There was a house we looked at when I bought my old home that was built by the technology department at IU. It was completely self efficient and relied on no external power from the power company. They did however sell power back and there were weird fuse boxes and transformers still hooked up even though the equipment was gone.
It’s difficult to tell exactly what’s going on there, so here’s my guess.
Power enters at the bottom right to a standard junction. Cables leave junction above and go to standard 60A fuse; thence to your meter and consumer unit. 1 cable is spurred off from that 60A fuse to another (unusual) lead tag sealed 15A fuse which is unmetered at that point. I can only see a red cable then going to a brass(?) gland. I assume there is a black wire somewhere and that they feed (or fed) the box outside which some service provider* pays for on an unmetered basis. Very interesting that fuse being sealed like that! I very much doubt you’re paying for anything other than your own electricity.
*Rediffusion sounds a distinct possibility. If so, I’m guessing the wire from the eaves is an aerial cable and the wire on the wall to the right of the box is TV distribution. There will be an rf amp in the box if it wasn’t decommissioned last century.
Just my guess, could be totally wrong. I’m intrigued to know the real answer though - more pics showing wiring to the left would help.
Have a go at the red wire with a Draper Non Contact Voltage Tester. It’s possible there’s no fuse wire in the small 15A fuse and they just left all the wiring in place to save time. As electricians tend to do. And plumbers. And …
Don’t tell me, you’ve just been given some nice herbs and a hydroponics kit …
I’ve had a good google and can’t find any references to Rediffusion boxes that look like yours. They did put boxes on the end of terraces and then feed cable out to subscriber boxes from it - no pictures though.
In any case, it’s so old (guess late 40s, 50s) it can’t still be in use. (Those vents look as if it housed valve equipment.) I’d eyeball the cables as far as possible to other houses and, if nothing obvious occurs, I’d rip the thing out. I’d probably check with the local council to see if there were any reference to the box first though.
I don’t know where you are in the UK, but some places like Hull got up to several cable distribution wheezes that subsequently disappeared.
Good luck. Let us know what you find out!
