Warning - Rant
Went out yesterday to look at a interior porch light that wasn't working...dead as doornails since the front door was replaced....A year and a half ago.........
Get there, light is dead, wiring a bit of a disaster inside the switch box (scruits and corroded CPCs....seems the porch had a water leak recently that went unnoticed for a while....looks like it was running down the cavity and humidity has been hitting the unsleeved CPC), sort out the jumble, (looped in at the switch)...check the fuse (in the back of a cupboard without any light and at right angles to natural light so pitch black)....not blown, however the upstairs fuse is blown, swap them over, upstairs lights come on....nothing at the porch though.
Closer look at the fuse carrier for the upstairs lights....heat damage to carrier and looks like its been arcing and trying to set itself alight. wiring looks ok with no damage. Inform the customer that CU needs swapped out, they agree after I show them the fuse carrier.
Thats when the....fun starts, lift the floor....slope up to the hatch and a gap of 12 inches at the highest and about 6- 8 inches at the tightest with what looks like a streets worth of builders rubble in the bottom. 6mm2 Bonding disconnected so replaced it with 10mm2. Took about 3 times as long due to the lack of space and the mad collection of pipework the plumbers had ever so helpful run all over the place:censored: (much banging and scraping of various appendages occurred )
Manage finally to get out, get the power off and the old box disconnected, mark whats what with tape, eventually find a space the new (small) CU will fit into...getting on reasonably well, though notice a few "oddities" to be investigated further (left one cable disconnected.....6mm2 T+E connected directly to the fusebox incomer with no overprotection....informed the customer, agreed action is to look at it later, in the meantime she will keep an eye out for anything that isn't working....and also looks like someone in the past has spurred a socket directly off the ring fuse rather than the ring itself due to a lack of ways in the old MEM rewireable fusebox, so looking into that further next time)
Light is fading by this point
Then the head torch goes on the blink :censored:, thankfully I have my spare LED torch that the customer offers to hold so I can get finished and then.....discover the tails are 1 inch too short ( literally an inch, due to having to move the CU from where I intially wanted to put it due to space issues).:censored::censored:...tails split in the past by someone years ago so relocated the ancient henley type block (live and neutral in 2 different bars inside one enclosure....probably original to the 1969 house or not much newer) serious fun as some muppet tore most of the head off the mounting screws, which made them a pain to remove.....) and then the back of the henley decided to crack.... :censored::censored::censored: brittle as brittle can be....
Got the cover on the henley (agreed course of action with the customer is to come back and replace the henley with a pair of modern replacements and renew the tails), energised, everything working ok (apart from a heart stopping moment when the upstairs lights took a few seconds to come on...cold old CFLs).
Though customer had cash waiting, (makes a nice change for someone not to quibble over a reasonable price) and left me to crack on apart from asking if I wanted a coffee etc at various intervals
The last piece of fun being my ratchet straps did a vanishing act, so tied the ladder down with some rope and got taken for £18 in B&Q for 2 (small B&Q thankfully just round the corner).....though had no other option as it was almost 6 by this stage and it was blowing a gale.
Next time - Try and find whats stopping this porch light getting power including drilling out the screws holding the back box in place as the head has been totally stripped off by someone in the past....replace the tails and the henley with 2 new separate henley blocks in 25mm2.
I'm glad I have a day off today....my patience needs a break from dealing with bodges, my back is turning black and blue along with my knees, shins and elbows....seriously I should have been a commando....:P

I know...just a bigger pain in some respects than usual...could have been worse...couldhave been my house...that has no underfloor gap, just enough for the cables to run through, or the customer could have argued the price. At the time it just seemed to be one thing after another after another after another lol. Especially after I'd cracked myself for the umpteenth time while trying to sort the bonding
 
The rest wasn't much better, one of the socket rings was showing the start of similar signs, given that the box was installed in 1969...I took the view its probably long past its best and it could be one thing after another. Plus the customer has kids (albeit teenaged), so not ideal having rewireables.
Gave them the quote, outlined the benefits of RCDs and MCBs, they said "fine go ahead". Glad they did as there were a few potentially serious mistakes (6mm2 T+E fed straight off the incomer, heading who knows where up through a wall)
 
that 6mm could have been shower. no spare ways so numpty wired into incomer.
 
Thought that....but below the fusebox was a single way 45Amp rewireable fusebox split off the tails via the aforementioned henley, electric shower decommissioned already in favour of a mixer shower....cooker was already in the fusebox and the old 15Amp immersion circuit is fused down external to the fusebox via an FCU to fire the gas boiler.
Bit of a mystery to be honest, Could quite easily be redundant as theres a lot of stuff that previous owners have added that the current owners have pulled out in the years they have lived there.
Spoke to the customer and she was ok with it being left disconnected "give me some excitement trying to find if something doesn't work between the housework" says she.
Used to do it in IT on rare ocassions....if something wasn't labelled and no one had a clue what it was for, disconnect it and wait for someone to scream blue murder about something not working...often quicker than spending time tracing out the wiring. Often get a phone call 5 mins later...this has stopped working or my printer just vanished off the network....ahhh thats what its for...reconnect and label.
Last but not least...I so love the the "fun" of releasing cables from metal fold over clips which have been covered in umpteen layers of white gloss paint, then trying to get gloss covered cables to bend or go through knockouts...
 
.if something wasn't labelled and no one had a clue what it was for, disconnect it and wait for someone to scream blue murder about something not working..
that's a better way than reconnecting it and then waiting for someone to phone up saying her husband's in intensive care from finding a cable end behind the wardrobe he'd been dismantling.
 
Indeed......my thoughts exactly.....or a visit from the plod / lawyer charging you with manslaughter due to criminal negligence...or seeing on the telly said house ablaze.......
 
eggsackly
 
well can i have your job please as I have had the ultimate PITA day driving around streetlighting feeder pillars doing visual inspection and Ze tests, then entering the information onto my company PDA, in my company van, then home by 4 to walk the dog.

And they queue up on here day in day out on here with the ambition to become 'domestic installers' !!!.........
 
:wink_smile: LOL doesn't sound that bad of a swap, sounds better than crawling over broken bricks anyway
 
BTW,why does a socket spurred directly off the ring fuse warrent 'looking into'?
 
Because I don't know for sure that it is just a socket, single 2.5 in addition to the ring cabling that then dissappears under the floor and up through the wall somewhere. Same thing was done on the other ring, so it potentially could be a third ring connected to 2 separate breakers.....I could have been clearer....apologies for the confusion.....
 
So today went a lot better than last week....tails replaced, henleys renewed.

Also found the 3 wire issue
While doing some other work (earthing a class 1 luminaire that someone had failed to earth)....looked up through the ceiling hole and caught the glint of copper with the torch and black and grey PVC...underneath a bedroom floor between the floor board and the joist it looks like.....explains why the RCD on that side of the board has been randomly tripping with no obvious cause (Asked why she hadn't phoned - "nothing we couldn't live without" and "it didn't trip out when I reset it")....someone steps on that floorboard...pushes down on cable creating a fault.....Customer is going to get her husband to empty the room above and get the floor lifted (he is industrially electro/mechanically trained but works odd shifts frequently, any wiring he has done though is neat, tidy and to the regs - Alarm install in particular extremely well done) and if her husband can sort it out he will, if he can't / doesn't have the time then she will give me a call.

Also tracked down the porch light issue....door fitters caught and crushed the cable with the frame, so need to arrange a time to replace the cabling (customer wants it replaced as its only about 15 feet from the CU and runs underfloor and up right beside the door) though again her husband might get the job as he is due some time off........some holiday for him....lol

Lastly turns out the mystery cable feeds a shed with a treadmill supplied by a 2 way metal clad board (5Amp MCB for the lights and a 20Amp socket radial but with an RCD beside them).Seemingly husband had went out to use the treadmill and of course no power....shame she forgot to mention the shed when I was trying to figure out where the cable went.....sorted now though.

You might have missed a trick there. You say the mystery cable "fed" out to a shed. You also say it was originally terminated into the main switch.
It was clearly a treadmill powered backup supply in case of power failure.
I've seen it done before.
 
pretty poor backup plan.....husband only uses it and he works 60 odd hours a week and the dog is fat so it never uses it either.....better with candles and a genny ;-)
