Did a bit of testing recently for our local housing association. Found this in a communal area at the front door to a block of flats:
Yep, full of water!
Turned power off and drained:
When water drained battery backup kicked in! (Circuit was protected by 3036 fuse):
Also found this in a property, usual story, loose connection:
Not housing association but just as good:
The next one was a good one. Testing a village hall recently and having a bit of trouble with two "radials". Turns out they were wired as a ring and when someone nailed the cable and they couldn't find the fault (or didn't bother looking) they decided to change to two radials. We did a bit of digging and found this, which has been like this for about 30 years:
Needless to say all has been rectified except village hall which is looking like a full rewire is on the cards.
