Flicking the V

[Benway]

Why are my incoming electricity cables flicking me the V?



Thanks.

do you live in a terraced house, or a semi, and is your neighbour on the other side of that wall?

or are you in a downstairs flat, with an upstairs neighbour?

show us where the cables go.

 

[Benway]

Detached property. That wall is mine. They just disappear into the ground.

I do not live in any of those, and my supply cables are like that.
One is the supply cable in and the other goes under the garden to the (detached) house next door.
Its a fairly normal method for DNOs to provide the lekky service.

I haven't seen it in detached houses, but maybe it varies by region or age. I thought the pic was indoors, but I can see now it is an external box.

One pair are the supply to your house, the other is likely too next door
Each pair has a live and neutral
left 2 are the Lives to the bottom of the fuse carrier
Right 2 are the Neutrals

Thanks all. Makes sense.

Cheers.

Not any longer, not for many years.

I my house was built late 70's, I guess things have improved since then!

I have seen this method employed on houses of all types and age up to the 2000's.

In fact I spoke to a DNO guy who was installing domestic supplies a few years ago and he said they use 35mm² to one house and piggyback in 25mm².

 

[Lectrician]

My DNO will never piggy back supplies these days, only ever one cable per service head. They will take a 35mm ABC to an outside wall and then drop two 25mm down. 16mm drops have now been dropped.

My head has two cables into it. House built in 50s, cable is PILC. Head is fixed to an internal wall in the middle of my house, not adjacent to a neighbour. Floor is concrete, no indication where the cables go. YEB region, but I've seen many different methods used by them. My old house had a head on a party wall but only one cable into the concrete. 1911 built, PILC cable. My mums house has cables strung across 5 houses in a row, put there in 1940s and replaced in early 90s. Feeders put underground late 90s but cables between houses still visible. All YEB/YEDL/whatevertheyrecalledthisweek.

My terraced house supply is wired like this as well. Overhead cable comes to mine, then piggyback cable goes off through my house to supply next door. Suspect the cable might be a bit undersized - my lights dim slightly when I turn on my electric shower. Next door has just been renovated and extended, including underfloor electric heating throughout. Not sure if it's going to be an issue, but nobody has picked up on it yet (next door hasn't been lived in since work was finished).

Could be an undersized service cable, but could also be caused by other factors. How big is your shower?

Shower is 9.5kw, on it's own circuit from the CCU with a 40A mcb. Wiring looks like 6mm t&e.

ETA Just measured the voltage drop at a socket as 11v when the shower is running.
