Just installed a small length radial circuit. Total length from board no more than 2 meters. Halfway along is a FCU and a double socket at the end. Linked line and earth and tested at the socket and got a R1 R2 reading of 0.10 ohms,hit the switches to confirm polarity and the reading stays the...
Evening all. Working on a bungalow at the minute with the dreaded stramit walls.
All my new cables have been surface, galv capped and the builder is dot 'n' dabbing over. There is an existing radial serving sockets in the living room which is not being rewired. For those that are familiar with...
I started installing a radial circuit in 4mm² singles in white 20mm conduit for an office. MCB=32a. T-N-CS
The client has decided to cut costs and while the builder is erecting a stud wall partition office he (the builder) will continue with the wiring. The builder wants to form a junction with...
Hi guys. I need to check if I have a ring or 2 radial running from a fuse. I have an old wylex fuse box in which someone has put a blue 15amp fuse in a red 30amp carrier.
If I disconnect the 2 cables and check for continuity of the 2 lines then the 2 neutrals will this tell me if I have a ring...
I'm getting some unexpected continuity results.
r1+r2 = 0.11
rn+r2 = 0.11
r1+rn= 0.14?? I was expecting something in the region of 0.08??
I have left the job for now. Any thoughts?
Thanks in advance
Hi as above i currently have a Radial from CU in cupboard that powers one socket (powers 13a heater) outside the cupboard can i (DIY) add a new socket inside the cupboard between CU and existing socket? The intention to have a socket in that cupboard to power a chest freezer
Thanks for any...
Been told today by an nic chappy they no longer apply it even when conditions allow . Asked him for the reg and the reply was ( i dont know the reg but its in the red book ) .
Hi gang,
Sorry for the massive 1st post. And hello!
I am just about to take possession of a house. I have a blank canvas for all work - the house was a council built old folks home but is now a "Change of use" category. I have no electric supply (Or water) but that is in hand. 4 bedrooms.
I...
Hi all,
I recently started training to become a domestic installer. I have some practical experience and some knowledge of part P. Also done a little testing but only continuity and insulation resistance.
A friend of mine is fitting a new kitchen and will be having two ovens side by side. He...
Changed a CU today and noticed the kitchen sockets were wired in 4mm t&e surface mounted in trunking and on a 32A breaker. Now, the CCC for this is strictly only 30A (ref.method B). Would anyone be overly bothered about this? Common sense tells me that it is unlikely this cable will be asked to...
Hi all,
Having currently finished a new install comprising of offices and an adjoining warehouse we have now been told by our QS that we need to change upto 99 breakers across 17 DBs!!!!
Basically we have installed a lot of 2.5mm T&E radial circuits serving floor boxes. The runs are a max of...
I was called in to a recently finished house extension as the heating wasn't working, plus they needed
the alterations tested for building control.
There was a kitchen extension to the back of the house plus a 2 store extension to the side which was an office downstairs, plus 2 bedrooms and a...
Hi,
First off I apologise if there is already a topic going for this or if it is a daft question. I'm currently in the first year of my course so any help would be appreciated.
How would I go about putting a timer on a Radial circuit that has about 3 sockets on it?
Again any advice on the...
Hi all,
I have been asked to add a couple of sockets and add power to an existing strip light (currently disconnected) in a garage. There is presently an SWA 2.5 mm cable that is apparently live but taped up, hanging loose in the garage which is fed from a 32a ring circuit located in a utility...
Hi there.
Just a discussion with a colleague.
Is it acceptable to use a redundant 30A cooker circuit wired in 6mm, and downsize to 4mm via JB for a kitchen radial?
For example, if there is one ring supplying a house and you would like to reduce the risk of overloading with all the...

Hi Gents,
I've recently built an extension onto my mums house... bedroom, wet roon and kitchen. 3 double sockets in bedroom and 4 double sockets in kitchen above worktops... all on a 2.5mm single ring to a Starbreaker CU. Originally all the apliances (combined fridge/freezer and washing machine)...
Hi. I own a large shed, currently served by 1 single socket, so need to make power points more accessible. My plan is to run two radial circuits, one down each side of shed with 4 double sockets on each circuit. Idea is to use 4.0mm2 t&e on a 32A rcbo for each circuit. Cable length from CU to...

So you can spur off Spurs on a radial socket circuit, is this because the cable is protected via a 20amp breaker at the board compared to 32amp on a ring?
As above why is this as I have had a thought and a 20a 2.5 mm cable would be sufficient?
Even in my new built it has an oven and hob both 32a radials for each on 6mm cable? Each with a 13a plug on the appliance as diversity shows around 10a max.
so even with an upgraded appliance I don't see...
