one of this weeks jobs

i would have gone down and along

its possible that M107 has done the same thing, and the 'chase' is from removing old wiring

 

[M107]

It was indeed the old original chase, I enlarged the chase & installed galv tube post the picture.

I have a question.On looking at the first pics you posted I see a diagonal chase from the cooker switch to the cooker outlet and assume (note I said assume) you ran a cable in that chase, would I be correct in my assumption?

M is a proper sparks don't mess with him.

The things on the end of the cable....a phone charger indeed...... are infact Ashley J501 junction boxes (what Ashley call 17th compliant JB's).These are the feeds for the pelmet lights when the wall cupboards go up, higher up the wall are a couple of loops that are behind a blank plate, these can be used to loop in/out of a transformer that can be sat on top of the wall cupboard if elv pelmet lighting is wanted.

As pointed out the MEB to the gas is a loop through & is on going to the water, my thinking is the crimps look very nice & tidy but with stranded conductors I preferre direct contact to the clamp with the conductor unless it's a bigger csa & a hydraulic crimper is used.

I have no problem posting pictures of my work, constructive critisim is always welcome as none of us know it all, and besides I wish when I was at college I had somewhere I could have viewed some hands on pictures of how others undertake such work.

indeed M, i find it very helpful to see how you guys do it, like putting all cables in netral and earth before putting din rail in, and that eath rod, wow nice idea, just one thing on that, is that a galv box on the wall? is it earthed?

depends where the cables are coming from - if i have trunking above CU, then outer is stripped back there, and each circuit wired into earth/neutral/mcb at same time. if coming from bottom etc, then i sometimes take the din rail out, wire earth/neutral, and label live ready for MCB later

Are you assuming I'm not? I have over 20 years of experience under my belt, did I mention it's a black belt? :^O

I didn't think for one moment that M would not have done a proper job, but he will keep putting these pics up of half a job

A very nice job as always, keep posting those pics.

Looking through you piccies M107 and thought of a few questions if you dont mind (or anyone else can answer too)

1) Do you always cut wooden backboards to put the cu on the wall. Is it because sometimes the walls or not perfect and when you screw the cu back tight it bends it sometimes so woods a better base?

2) If the cables are going to be covered dot and dab why did you use trunking? was it to save clipping loads of cables to the wall plus it keeps them all neat and tidy?

3) How did you 'clock' that there was borrowed neutrals before you tried it on the new board and it tripped (if you get what im saying)

4) The gas/water bonding. Is it one cable unbroken to both service pipes?

5) The bathrooms got 10mm bonding conductor. Where does that go to ? and why is it needed?

I know these questions are basic but im just trying to learn. Thanks again for posting you pictures as it really helps out.

Cheers

1) Do you always cut wooden backboards to put the cu on the wall. Is it because sometimes the walls or not perfect and when you screw the cu back tight it bends it sometimes so woods a better base?

Not always as it depends on the state of the wall, here I used a backboard as the cu was fitted prior to the wall being dot/dab'd & didnt want the cu to be platered/boxed in. My advice is think ahead & dont rely on other trades, here I was lucky & the plasterer was spot on & came to me for a view on how we planned to get the job done (needless to say I've taken his number to pass on)

2) If the cables are going to be covered dot and dab why did you use trunking? was it to save clipping loads of cables to the wall plus it keeps them all neat and tidy?

No.. Again thinking ahead any new cables will be easier to pull in through trunking + made the job neater but no reason the cables couldn't have been clipped direct.

3) How did you 'clock' that there was borrowed neutrals before you tried it on the new board and it tripped (if you get what im saying)

Age of the building (learning from old boys pays dividends) & by dropping the landing light, looking in the loft & opening the hall & landing switch plates.....Finding that a single T/E used the neutral from upstairs lighting circuit from bathroom light to the landing light.

Or you could dissconnect all conductors at cu & continuity test between each neutral in turn (long winded when sticking your head in the loft might show the problem straight away)

Or the lazy way you could just connect up & see if the rcd trips when the 2way switch is operated.

4) The gas/water bonding. Is it one cable unbroken to both service pipes?

It is. I strip the sheath seperate the conductors & first BS951 put the screw through conductors, tighten screw & carry meb unbroken on to next BS951.

5) The bathrooms got 10mm bonding conductor. Where does that go to ? and why is it needed?

This was installed at last rewire or bathroom refit. It terminates at a junction box in the loft above the bathroom & then feeds off to all circuits cpc's in bathroom & pipe work in bathroom/airing cupboard (in old money supplimentary bonding). Having now put in MEB to water & gas & the use of rcd's I could have removed it, but why take the effort when it can still be of use as a supplimentary bond.

I know these questions are basic but im just trying to learn. Thanks again for posting you pictures as it really helps out.

No such thing as a basic or stupid question, if you dont know how are you supposed to learn without asking?

Always a pleasure to post pics of my work (cant help it I just love sparking), I like to think I take pride in my work & as the customer said when he saw the cu & installation at this property "that is truely a work of art, I never knew so much was involved" Make it neat & it'll be something the next generation of sparks can work too is my philosiphy.
