Progress.....

[Lectrician]

Remember the below pic? I posted it at the beginning of the year with regards a circuit I had to connect into this mess.

Well, it's that time of year.

We have forged a temporary 100amp supply, and run some of our exhibition distribution cables and boards around to power the things that need to stay on - Shop, Freezers, Office, Phone System etc etc, and ripped the guts out!

Feels good to rip it all out!

Unfortunately the DNO have deemed the metering kit to be in a good condition, and are not going to renew despite the rust. Shame. If they turn around in 12 months and say they are going to, then they will have to get a CT chamber the same size, as my galv trunking will be in and fixed, and I will not be moving it! They have been given the oportunity several times to replace

I bet that felt good ripping it all out

I assume we'll see the finished product

Also should you be at work following Op

i know a great way of removing unwanted MEM's and wylexeseses.
Instead of fuses lob in some plastic explosive, and run like the dickens!

Feeling good, and this was programmed in for a long time. The site has had to make sure certain parts close for this week, I have booked the DNO to connect new 95 tails on wednesday, I have had exhibition stuff shipped down from where we have it stored, and turned down a job where the kit would be used this week because we needed it here. It is far to logistical to say 'prospone', and I don't want others doing the job!

Tails in trunk are nice and tidy on my end, and loose ready to drop into CT chamber......thats why they are wavey before any clever remarks are made! 95mm for those interested.

You may think the stickers are a little OTT (especially the large NIC one), and maybe a little oddly positioned......there was method in that madness though



DNO came on Wednesday to connect tails to the cutout. The chap that turned up was on his first job - litterally. I ended up helping him (actually doing it for him!) - He wasn't keen on restling the cables down into the cutout. To be fair, the tails are not standard single insulated 6491's - They are double insulated XLPE which was not what I ordered, but too late to change, and better over specced than under. XLPE are much tougher to bend and form.

I had thought I had some pics of the insides - Cant find them on my phone. I will be going back anyway to do some finishing touches, so will try to remember to take some more pics with covers off.

Methinks this shoulda been in trade talk.

Why?

A little beyond the scope of DIY?

a very nice job but i may have spotted a problem....

how are you going to perform the Ze test on that install?

best wishes....

Nope; it's good to show that the correct way to do it is neat, tidy and safe.javascript:emoticon('8)')
Cool

Oh and I am impressed - this is teaching by example and no mistake.javascript:emoticon('')
Very Happy

Ah - You tell me

A slidey jobbie on the main earth bar?


Looks a hell of a lot better.

OOI how long did it take start to finish?

 

[partpdoctor]

Ah - You tell me.....

i dunno from your pics but.....
if you have bolted your trunking to the ct chamber you could not perform a Ze check as....

when you disconnect the earthing conductor the trunking is still connected to the head (parallel paths and all that)....

i am only commenting as i was pulled for it a few years ago by my niceic inspector, the trunking should be "insulated" from the head, and i thought i had done a real nice job

I have used paxoline between the CT chabber and the trunk - The paxoline is gutter bolted to the trunk, and the slot in the CT chamber is slighty oversized to miss these bolts

Removing the main earthing conductor is all that is required to conduct a Ze. This is actually a stipulation of our DNO - I have not done this to keep the NIC happy.

All in, it has taken 5 working days. This includes re-routing many of the cables that previously entered above to enter from the other direction, the removal of several old submains, and a rewire of the pool plant room which this is all sited in - previously clipped direct wiring - thr trunk now goes around all walls with conduit drops down to the pool pumps, calorex heat exchanger etc etc.

A good half a day was also spent running out several hundred meters of temporary cabling to various buildings spread across the site to keep them powered. We actually connected some cables directly into the DB's in some of the buildings, the others just had an array of trailing sockets from our exhibition kit. This also all had to be packed away.
