Customer has a 25mm sub main fed into DP isolator (as pictured) then 16mm T&E out of the top to feed 2nd consumer unit about 20m away. 2nd consumer unit has 8 circuits. (1 32A Ring, 2 socket radials, 1 lights, Shower (pump fed no heater), Immersion heater, 2 Ovens). Diversity & cable rating...
Hi,
I have a commercial property with several consumer units that are the old split type ie half rcd protected and half not, the boards need replacing but on some of the boards they have a breaker on the unprotected side feeding another consumer unit, ie a sub main in T&E , so when I replace...
Which table do you use in BS7671 for volt drop for LSF Twin and Earth? There does not appear to be a table for LSF cable. 4D5 refers to the grey PVC cable and is not the right one to use for the white LSF. Any help would be appreciated.
Guys, I've need to run a cable from a CCU, through a wall (which has a garage on the other side), then run (10mm, 3 core) armour to an installation. What I would like to do is run 10mm T&E from the CCU through the wall ('cos it's easier to manipulate in a confined space obviously), straight into...
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...
Morning everyone,
Hope your all well.
Just a a quick question. We have been asked to quote for a HMO conversion, in a domestic property. So basically, the developer buys these houses and makes rooms out if them.
Leach room is basic, small ensuite shower ( not electric ), lights and a few...
Hi,
I've been asked to change a CU in a converted one-bed flat immediately above the cellar which contains the TNS supply. The existing CU is currently supplied by a 6m run of clipped direct 10mm T&E protected by a 63A switch-fuse in the cellar. It's a small flat, haven't worked out maximum...
Running a 20A 6.0mm T&E radial to utility room to supply two single 13A sockets to feed Washing Machine and Tumble Dryer.
The T&E will be terminated in a PVC adaptable box, just wondering how to make the connection to the sockets as terminals
will not take 6.0mm.
Can I use connector strip...
Hi All, a customer asked me to look at his supply to the garage which had been installed by previous owners. The garage is approximately 2 maybe 3 metres from the house and as far as I can tell is fed from 2.5mm T&E spurred off the ring. The cable exits the house through the wall about 2 .5...
Scenario:
In an old house, the main fuse board is next to the supply intake, which feeds sockets, cooker, immersion.
For the lighting, there is a separate sub-board in the centre of the house, fed by a 2.5mm T&E distribution circuit from the main board.
This 4-way sub-board is antique, cast...
Hello,
I've been asked to run in a new circuit for a dishwasher in a school staff room.
I've planned a 20amp / 2.5 T&E radial feeding a 13amp fused connection unit and fixed equipment connection point.
The planned cable run includes running across the ceiling of the plant room (2/3...
Recently I had a job where I had to cut a 6mm and a 2.5mm live cable and terminate into a JB. I had to strip the cable with an insulated stanly, and then separate the wires and terminate each one.
I was just wondering if there is a tool that would do this cutting job without having to separate...
Hi, I'm trying to find a 100m reel of 2.5mm twin & earth cable if anyone has a spare reel, maybe you don't use it any more or you're retiring soon.
(sorry couldn't resist).
Hello, my first post!
I've lifted the floor boards in my Bungalow and found that there is a void between the rafters and a solid concorete floor. This area being ventilated by air bricks at both front and rear of the building.
Given the depth of the rafters drilling is not really an option ...
Unbelievable!!! Last week, bathroom refurb, the shower was removed an 8.5kw mira, it had been supplied from the pullcord in 2.5mm t&e, there was no thermal damage to the cable. The customer says it was there when they moved in, 8 years ago. I cannot believe it has not caught fire & there was no...
I'd appreciate peoples views on this, including compliance or otherwise with the regs.
I've come across a 1-bed flat where one ring main serves the small kitchen, and boiler & security alarm. The unusual thing is that the ends of the ring are then connected to a single 6mm T&E that runs back to...
Hope someone can help.....
I'm looking for 2.5mm XLPE/LSF/6491X
It's been speced for an internal access control system, supplying the fused spurs. Is it just regular LSF T&E or something else?
Thanks in advance.
This is the current set-up.
There's a TNS incoming to a detached garage, this is split from an old MEM fused isolator (the tails go straight in) and has a send to the CU via some 10mm T&E going under ground and up into the house. There's another feed from the fused isolator to another, smaller...
7 flats, 8 seperate DNO Meters with contractor isolators for each. Lovely up until now.
Then the tails to the seperate flats are wired in 16mm T&E which I absolutely hate as the earthing conductor is not sufficient in my opinion.
Thoughts?
