I'm completing a job started by another electrician (oh the joy) and the client has all the ordered materials on site as the previous guy instructed them.
One thing I have to do is re route the armored cable between two CU's in a large outbuilding as it presently runs where they are planning to...
I've been let loose today to do a PIR, EICR, E, I,E,I, O what ever they wanna call them these days in an empty flat and have an annoying CPC broken in RFC.
2 bed flat
3 way CU - Cooker (30), Lights (6) and RFC(30)
End to end of r1 and rn fine but r2 is broken.
This is what I did-
connected...
Hi All, I'm a DIYer after advice please.
All the lights in my house (ground floor and upstairs) are on one circuit - old colours, as you might expect with the age of house (120 years).
There is a cpc (earth) from the (modern) consumer unit to junction boxes on both floors of the house -...
Hello all, I have been ask to run power to a couple of AC units in armoured cable clipped along the outside of a new building.
It is going to require 2 separate 20amp circuits so was wondering whether I could run a 4 core armoured cable, giving me 2 lives and 2 neutrals then using the armour as...
This has been posted about a lot but I wanted to ask a really stupid question. I can only run 4mm single g/y to each metal fitting from the board which is dual rcd 30ma. I cannot touch the drops, stipulated by the landlord. Is it acceptable to issue a mwc for this, write a safety letter and...
Hi guys, Im banging my head off the wall on this one. I have to run in a new 200A per phase supply. The cable length is 35M. Ambient temp is 20C. I am looking at table 4D4A in BGB and as it's to be on tray so Im thinking a 70mm CSA 4core as it has a Current carrying capacity of 207A (I am...
Hi Guys
I have been asked to quote to install a MET for a TN-C-S system and I could do with some advice please
I can't get into determine the size of the conductors as I cant switch the power off to open up the main panel
What I did was measure the circumference of the SWA it was 214mmm I...
Went to a job the other day, where the client wanted a light fitting put up instead of the ceiling rose. In conversation they mentioned having problems with their electrics, and had had a new CU fitted. I decide to measure ZS & RCD at the said ceiling rose. However, my tester (Megger1730)...
Testing 2.5+1.5 socket ring, got r1 0.75ohm, rn 0.76ohm, r2 1.38ohm. Expected r2 is 1.25ohm (=0.75*2.5/1.5)...bit of a deviation. All CPC connections inspected appeared fine. Had a micrometer to hand (not calibrated admittedly) so measured conductors, live = 1.77mm dia, CPC=1.30mm which gives...
on a schedule of circuit details for a installation certificate, under the circuit conductors cpc size in mm², what should be recorded when a SWA cable has been used but one of the inner conductors is used as the cpc (say single phase circuit supplied by 2.5mm² 3 core, 1 x phase, 1 x neutral, 1...
Hi,
Had to change a bathroom fan at the weekend for someone and they wanted it to be on a timer, but couldnt as the cable was buried in the wall and wouldn't move etc..
the cable that fed it was a three core flex, I the earth was not being used anyway due to the load on the end etc.
I know...
Hi Guys,
I have been asked to install a some lighting & sockets in a lean too come garage come workshop type of thing. I was going to do it in PVC conduit & make a proper job of it rather than surface clip T&E all over the place. I haven't done much in the way of circuit installation using this...
Hi people
Maybe somone can give me some pointers, Generally with faults i'm pretty good but this one has got me stumped!
I was working in an old house that the owner required some modernising, so we did a kitchen and moved and added few lights and switches around as you do. The board was an old...
Excuse what may be an obvious question here fellas, so I apologise, but I'm having a real brain fade after a bit of a trying couple of weeks at work (other work, not 'here')......A customer has requested that I install 3 x 12v downlight fittings to a small ensuite. My question is that as that...
Hi all again
I'm doing another condition report for a property, no cpc for sockets, cooker lighting, what's the best way to test continuity, I'm thinking of doing the same way as R1+ R2 line to earth terminal, also would you record results in r2 box or R1+ R2 box, I'm having a bad day
Hello folks,
I hope the picture shows ok. If it does not show, then basically there is a blue disc approx 25mm in diameter that may have a resistor or something in it. It is approx 4mm ' thick'.
The blue disc is linking between neutral and earth on the fitting. Never noticed these before...
Hi everyone,
Hopefully someone can help me with this?!
I am in the throws of finishing a domestic rewire in an empty house this week and yesterday was re-sleeving some CPC's in pendant light fitting that my apprentice had sleeved poorly.
Rather naughtily I was doing this while the pendant was...
and here's how it was overcome...................
this was found AFTER rewire when the ceiling was dropped....................no certificates funnily enough!
Hello there. I'm forever looking over these forums looking for advice, and typically I always find an answer, except it seems in this one instance - which is what brings me on my merry way to here today.
I was thinking of running a new supply to the garage. Problem is it has a water pipe (only...
