Had a call out to a tripping issue yesterday.
I found that the very old RCD was faulty, but upon inspection something didn't look right regarding the routing of tails.
I'm practising EICRs on friendly locations as I'm still in training - technically done my 2391-52 but frankly need loads more practise.
I've just done an EICR on a flat and a few things that I didn't know how to code/address came up:
1) How do you code (and look for) inter-connected circuits? I...
Hello everyone, I'm wondering if someone could help me with some EICR coding. I am aware that bringing mains tails into a fire rated consumer unit through separate holes can lead to some issues. I encountered this exact issue today for the first time and i am unsure whether this is likely to...
Was helping a friend out and changing their CU which had a date stamp from 1990. Good quality Merlin-Gerin unit and a nice job originally. They recently had a smart meter fitted and no isolator, but they had put in a Henley block in the L path so at least I could pull the load cable with a...
On a new build site how/ why are people getting away with installing meter tails over 3metres in length and behind dot and dabbed walls with no other fused iso's/ or protection on the cables.
Personally I use 25mm² swa and a fused isolator.
Just want people thoughts??
Just wanted to know which people use.
My case.
Client converting attached garage into new rooms. Consumer Unit has to move to accomodate this and will be greater than 3m from meter. Void above garage is used to route cables to main house so can use this to route cable for extension to tails...
Hi,
I was hoping someone with a little more insight might be able to shed some light on a potential issue I have, as I can't seem to find another example online where this specific question that has been answered.
What you can see in the attached photograph is meter tails (single insulated +...
Hi I have a domestic installation to rewire and the main incoming fuse is 80 amp so i am using 16mm double insulated tails, is the main earth size with this 16mm or 10mm ? Thanks
Hello again,
Was looking at installing yet another dedicated consumer box for my EV charger off the henley blocks and i noticed that a meter, which was installed a couple of years ago (outbuildings on the second phase of a split phase supply) has been wired with 16mm tails but with a 100a...
I’ve got a job to quote for turning 1 big flat into 2 smaller flats. The DNO are looking at installing new meters in the communal area. I need to take an SWA from each meter to the individual flats which one is around 15m and other is around 30m away.
Would a 25mm 3 core swa be the best for...
I've come across this incomer, looks like 10mm conductors.
The dno has upgraded the meter and used a 100A fuse.
So my question is, does this need reported or can I do whatever work I please along as I don't overload the 100A fuse 🤔
I’m currently doing some testing on some site temps I have a three phase trip system the tails from the head go into a 100 amp RCD which feeds a board I’m trying to do a pfc on the db but it comes up with 2 lead high which trips the RCD I tried on 2 lead low however came up with 20 amps which...
Evening all.
I have a question as I can’t get my head around something with solar PV
I’m going to be working on a new build in a couple of weeks as the contractors have installed the electrical installation incorrectly as per the customer request when buying and are now refusing to correct...
I've haven't got a way back to the main supply and need to add a consumer unit for a garage conversion but the tails are on a double pole isolator switch so was going to split the tails at the 60a fused isolator about 2-3m from the main supply is there anything wrong with this or am I just over...
Evening!
Once upon a time I would use 25mm meter tails which comprised of 7 strands. I now use a 19 strand version. The other day, however, I'm sure I spotted a very fine stranded version on a page on YouTube or in a catalogue/magazine etc.
Anyone know what this would have been and is it...
Hi,
I'm getting conflicting stories about this, I wonder if someone could put this to bed once and for all.
I'm replacing a consumer unit in the next few days, and it currently has the common grey tails going from the isolator to the existing consumer unit, one is ,marked "L" then other marked...
Hi guys,
Wondering if you could give any advice. Started a job today doing a shed install. They want a 6mm swa supply. The original plan was to come off of an MCB in the fusebox but it’s not going to be very accessible without too much damage.
Is there any ideas in what I could do in the meter...
Evening,
Carried out EV charger installation survey today & found this meter. Is that a 16mm concentric type cable adapter between cutout & meter?
This is a TT installation, tails unprotected. Not sure about installation method of DNO supply.
I'd like to upgrade tails to 25mm between cutout &...
Hi everyone, i might be having to run new meter tails from meter box to consumer unit which is just under 3m run, i have used 25mm 3 core before and its hard to work with especially through joists. I was thinking about 2 core 25mm swa and a seperate 16mm earth to make life easier but then came...
