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)...
Having gone back and forth through the onsite guide and BYB, am I right that with socket outlets in commercial premises it is the same as domestic 2.5mm and 100m2 ring main and 75m2 for a 4mm radial circuit? So application for diversity would be 32amp for first circuit and then 50% of every...
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?

Combi boiler on a dedicated radial circuit, has a FCU no neon with a 5amp fuse.
Any special precautions need to be taken before applying 500V DC?
Thanks in advance for any advice
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...

Hi everyone I've come across a weird situation where somebody has got new sockets added, but from the board it is a radial in 6mm as there is one set of cables into the breaker, then when you look at the sockets (2 double sockets) it's got 2, 2.5mm cables going into both like it's a ring
Does...
Hi I recently ripped out a ring final circuit out of an old Proteus 3ph board. Customer only wanted a single 2G socket replaced. The MCBs are obsolete so I had to re use the C32 used originally supplied the ring.
can I use 2.5mm cable?
32A radial but with 2.5mm cable- not something you would see...
Good morning all,
is it within regulations to add a spur to a radial wired in 4mm in a kitchen if the spur is also 4mm? The circuit is on a 32a rcbo.
Thank you
I currently have an integral garage fed by a radial circuit protected by a 32A MCB and wired with 4mm T&E cable. This feeds just two power points in the garage (and nothing else).
i wish to redesign this circuit to provide several more power points and would like to check whether my proposed...
Since doing a bit of digging am i right in thinking that using jb's to branch off from a radial circuit for a single switch and associated lights is considered "old hat" nowdays. ?? Ive read the 17th ed recommends jb's be of the maintenance free type is they are non accessible, which is all...
I have one single socket on its own from a consumer unit. (10A) (no ring) Can I swap this to a double and then spur off another double from it? It means there will be an equal number of spurs than there are sockets which I have been told is a no no. Is this true?
Thanks in advance
