I have a site with a three phase service head with only a single phase in use via a single phase meter.
Phoned the DNO,
"This is a job for the supplier."
Phoned the supplier.
"Won't touch the service head as its DNO property."
Phoned the DNO back,
"Send us a picture we'll have a look"

One of my landlords has an upstairs maisonette which will be changing tenants next week so will need an EICR - I already know there is an issue from a while back which I notified to landlord with a damaged 'Fuse Head'
This is how it used to be ?♂️ (Yes, live parts were under the "insulation"...
Good morning one and all,
I have a new build coming up (Hertfordshire) and was wondering what size fuse the supplier install now?
The reason why I’m asking is because a sub main is required due to the client not wanting the CU near the meter.
thanks,
An interesting sign has appeared on a local DNO distribution transformer, earths missing from Transformer and HV switch. Is this what is meant by a hot site?
Hello
Came across something like this.Is that something what i should report to DNO?.its supply to 2 flats.New cable on the left goes to first floor flat where electricity meter is.Its not SWA.All seals has been cut off.
If i report it do they come on short notice and put new service head etc.?
Are DNO cables in the UK fused before going into a building? And if so how? What happens if you were to short the cable out before the cutout main fuse?

Hi All,
I need to change a DB in a block of flats in central London (W2 postcode), where EDF can't give a date for at least 6 weeks to come and isolate the supply, but at the same time won't / can't give out a date after this, which makes no sense to me!
This is both options of just popping...
Hi,
We're getting an extension with flat roof soon, and I can squeeze 3kw of PV onto it so I was going to DIY the install, considering no FIT meaning a proper installation isn't cost effective. It certainly doesn't look out of the reach of a sparky without PV training so happy to give it a go...
Hi all.
I'm currently training as an electrician so would like your views on this for clarity and if I need to get someone in?
I have just moved in to a new (very old) house and on inspection of the CCU I noticed the incoming service cable from the overhead was chard at the top of the dno head...
Hi all, have been to a bungalow (well half bungalow half building site at the moment) and the main supply is in the middle of the basement. The dno supply is coming from above so is hidden in a wall and then I can see it going through the loft to outside. It's a good 8 meter run. Has anyone come...
What are people's thoughts on running a distribution circuit behind the DNO's Cutout?
I've a consumer unit mounted with no clearance above or to the sides and I'm struggling to find a route to it easily.
There is a possible route I could use, but it would mean running the cable behind the dno...
Hi guys I have a question, when we consider the assessment of general characteristics for any installation, who Measures /considers/ enquires about harmonics.
is that the job of a normal Installation spark ? If it’s not who does it and how do they test for it?
if it is the job of the normal...
Hi,
My installer (who no longer exist) didn't bother to inform DNO of the installation. I have got in touch with the DNOband they say they require me to contact another installer and get them to do 'commissioning confirmation and a suitable schematic diagram' for me to register the system...
My negotiations with the DNO continues.
Last year WPD told me there was no capacity for generation at my property without significant upgrades. Apparently the overhead conductor is relatively small and the loading on the network in the area is low. The combination of these two factors means that...
I've been doing my usual and watched a JW vid explaining what belonged to whom and it got me wanting to create a mock-up myself to practice on - I know we should only be touching consumer-side equipment but the purpose (and hope) of having the cutout is so I can setup the various earthing...
Hey there everyone,
I'm currently an EE student doing my 4th year project. As part of my project, I am carrying out a literature review into the design rules DNOs apply to their LV distribution networks.
I am trying to built up a reasonable understanding into how these networks are laid out...
years ago the dno fitted a 63A fuse but over time my needs have grown. is it a case of just getting the dno to fit a bigher fuse or are there other bits involved. meter tails are 25mm and about 0.5m long.
kind regards
Had the DNO out to check cut out, make a sheathed earth available today and pull fuse whilst I fit isolator.
Got talking about pulling fuses and the seal fairy, he said Western Power normally just give you a dont be naughty talk and doesn't get why they dont just allow registered electricians to...
I have been asked to upgrade a fuse board, however, when I did an initial visual inspection, I noticed the main earth from the DNO is unsheathed (TN-S), it’s strands that are clearly ancient!
I haven’t yet carried out any tests. Should I get the DNO to change the earth? Will they actually bother...
