Hi. I have my NAPIT first assessment soon and I replaced a CU in a house which has 16mm2 consumer tails in place. I did not upgrade the tails to 25mm2, so my question is should I have upgraded them or am I allowed to leave the existing tails in place?
I do not know the rating of the DNO cut-out...
Hi all,
Waiting for a bashing here, but it's something I haven't had to do until now so looking for advice on the best way to approach this.
I've been asked to replace a consumer unit for a customer but the existing meter box is recessed in the exterior wall - not uncommon I know, but not...
Good Afternoon All,
I have just completed a Periodic test on a house and have a question about the meter tails.
The house is 14 years old so has 25mm meter tails. The CU is in the garage and the meter box is around 7m away on an external wall as you'd expect. Looking at it, I imagine that the...
Does anyone know if there is a product for protecting mains tails in walls apart from conduit?
In sure ive seen stainless steel capping or something similiar that can be earthed and is drill bit resistant?
Afternoon,
Quick question. I’ve been to a job earlier to find a fault, but this connection was at the main switch. The first set of tails come from the meter and the second set are down to another duel RCD board. Looks doggers. Checked the Schneider manufacturing instructions and I was...
Hi all,
Just doing a newbuild where the DB will be about 8m from the cut out/meter box. 25mm tails run in conduit on the surface of the outside wall then direct through the wall to the DB inside the house. DNO have provided a (non-fused) isolator in the meter cupboard after their 100A cut out...
Hi all,
This week while wiring a very old farmhouse for heaters I noticed the incoming cu tails were very long, around 20 metres from the fuse and meter which is located in an adjacent farm building to the house.25mm tails (double insulated) leave the meter and go into a kmf switch (sorry I...
Looking at a job today and the meter tails were 35mm with a 25mm earth into a 100A SP TN-S with a 10mm soldered main earth.
Tail run, no more that 3m all clipped and a short run in trunking.
The 6181Y is doncaster cabel brand.
Measured the cable at 13.5mm OD and this confirms its definitely...
Evening chaps
First fixing a new build this week I’ve got a dilemma I’ve not come across before, the meter box is outside and the consumer unit is to go in the garage it’s on the same wall about 1.5m away but the meter cupboard is outside on faced brickwork and the consumer is inside the garage...
Hi all,been to look at flat today and it requires a new Consumer unit. Its an old porcelain type of fuse holder and shield and some of them are damaged. The flat is in one of these 60's built blocks with a meter cupboard on each floor. In the meter cupboard is the service head, meter and an...
Hello,
There is a 3 core underground armoured cable that emerges into a small "plant" room and from there it will connect to the consumer unit which is a fair distance and inside the property. A previous electrician (left when coronavirus) has already run meter tails between plant room and...
So i went to a job and i came across this the house is 19yrs old and apparently this is how it was when they moved in from when it was built its the twin and earth that runs to the consumer unit I am looking at there is some 10mm earth to the gas meter that has been fitted at a later date.

Hello everyone,
I have recently qualified, though yet to start practising, as an electrician.
I have noticed, at my home, the tails from the (single phase) 100A mains cut out to the 100A rated meter, from the meter, to a 60A isolator and from the isolator to the antiquated fusebox are all...
We've just recently bought a property which is around 25 years old and will be completing some alterations. The consumer unit is in the Utility high up on the wall. Isn't in the ideal place and we'd like to move it, due to a new kitchen layout.
On further investigation the meter tails run up...
Hi everyone,
Just been on a new build (one off build not cookie cutter), original sparks left some SWA for a car charger and electric gate that I have been working on, I have signed off these two new circuits.
The tails have been taken from a DNO supplied main switch, TN-CS with 100A fuse. He...
Hi All,
I need to split the meter tails to supply a second CU which will be at the rear of the house, however the supply to the second CU will need to be in SWA and I can only split the tails at the meter cupboard. Is there a suitable adaptable box or isolator I could use to be able to do...
Hi Guys,
Came accross an install today where a new 2 way board has recently been installed to make room for a new shower circuit (Db1 - 16th edition full board).
How the 'electrician' had wired it was by using 16mm tails from DB1 main switch which now has 25mm and 16mm crammed in there...
Evening all
Have a consumer unit change next week, the board is high level in a bedroom with 16mm tails buried in the wall. I’m replacing the tails but they don’t want any trunking in the bedroom, the mains is below for consumer unit I was going to trunk up the outside wall and drill in?
