Two houses fed of one houses mains - what are my rights.

[buzzlightyear]

Most DNO would have separated the houses with each own fuses. and both house should have their own main isolater.

Two fuses in the one premises was the usual way of sorting it.

Only if he did the work in the dark with sunglasses on. The wires going through the wall are right in the middle of the work area.

ive seen two feeds from one intake, but never one like that where the tails go directly through wall without any protection.

Called 'em out and they were sorting it an hour later. All OK.
The earth to next door was via the conduit. You can just make out the clamp connection above it.

PS. It's like the initial photo but with two fuses for protection, with a common neutral.

aye, its a cobble of a job but I've seen a few, you got to be a bit wet behind the ears/hungover/whats your excuse to miss it.

that and the guff about too many appliances being on, I'd be seeking an alternative opinion OP. Did you get installation cert and BC notification?

 

[freddo]

That's pretty poor work, I would not feel happy tightening that terminal in the burnt area and saying all is good, that connection is a known failure point in these consumer units, I've seen 2 now where a large hole has burned in the top of the enclosure over the neutral bar. Did he not recommend replacing the unit at the first overheating?

The bloke must have been blind to not have seen the other supply going through the wall, fed from the same fuse. That's a fairly old old cutout, I don't think I'd be pulling the fuse on it, not that I've ever removed a cutout fuse before.

That RCBO is not designed to fit in that consumer unit. It has has even been filed down on the front top part of the RCBO to get it to fit in the consumer unit...

I have an electrical installation record thing but not sure what a BC Certificate is

 

[freddo]

BC is Building Control. Replacing a consumer unit is notifiable work. To prove it has been notified you should have been sent a one page certificate either via the electrician or posted directly to your house. A sample certificate is shown here.

As above, the fuse is shared and power branches to your meter and to your neighbour’s installation (via the steel conduit). I agree this has not caused your problem.

 

[Guywithahouse]

Thanks, everyone i accept the overuse of electricals has not caused the issue thanks for all your advice.

 

[Guywithahouse]

Without putting myself at direct embarrassment, how much is average cost to replace the fuseboard with a modem one.

Thanks for this as when everyone was saying its well obvious I had no idea where to look. He said something like he has been doing it 20 years and never seen one go through a wall, I think he thought it was somehow connected to our inside walls or something... or maybe I'm making excuses for him

2 types.
1.dual RCD board so the circuitsa re split half on each RCD. downside is if the RCD trips, you lose half the curcuits. aveage cost installed £400.
2.All RCBO board. each circuit has it's own MCB/RCD combined so a fault will only disable the one circuit. average cost installed £550.

then there's options of Surge protection and arc fault detection both of which will escalate the cost/s.

I've been 'doing it' for 50 years, and I've never seen one go through a wall, but it's right in the centre of his field of vision, and blindingly obvious as to what it must be.
The only other thing likely to be connected like that would be a large 'weed' producing facility.

I paid £450, I guess its ok but not sure whether I've actually had work done which is verifiable and means jack all when I come to sell. We brought last year and there was no records of it electrics etc. So not sure if we'll be able to use this report thing hes left as proof.

 

[telectrix]

show a pic of the new board. with lid open.

Not easy too right now, but I will later.

 

[telectrix]

there are some glaring errors on that certificate/report. e.g. max. permitted Zs 5.82 for all values of MCB WTF?
main switch 60898??? should be 60947-3
several more that I'm sure someone else will comment on.

On the plus side, it does look like it was filled in using actual readings.
