socket circuit

[paddyscouse]

hi can some one advise me what to use for a radial socket circuit, i was thinking about 4 mil with a 32a mcb for kitchen

would then 2.5 with a 20a mcb for other room and the same for upstairs x3 beds

Sounds fine to me.

Use 2.5mm/20A Radials for other rooms, but a 2.5mm/32A ring for the kitchen?

 

[paddyscouse]

was not going to puting a ring in, hence 4 mill +32mcb for kitchen ?

should i use one radial circuit( 2.5 20 amp) for x 3 beds upstairs as long as i keep the run under 33 mtrs ?

also is there a limit on socket outlets for a radial socket circuit lets say a 33 mtr run at 2.5 20 amp or should this be 4 mill as osg states

I still think 2 x ring circuits in 2.5 would be easier and cheaper?
You have to be quite careful with 4mm on 32A and 2.5 on 20A especially where insulation is concerned, sorry haven't got the book to hand so can't give you the exact figures.
Rings give you an unlimited number of sockets in a 100m2 area.
just a thought

Personally, I use 4mm radials on a 20a breaker, and 2.5mm on rings. And that's it for sockets. Except the occasional 4mm ring due to existing insulation. For lighting, I now only use 1.5mm to allow for possible future covering with insulation.

Just curious, why would you not consider a ring circuit in possibly the most power hungry room/area in the house??

Not easy to provide a future spur/extension in a 4mm radial either....

A little bit curious why you are asking such a basic question. Should you be doing this type of work?

2.5mm t&e is easy to work with specially in kitchen area

Is this as opposed to 1mm, I dont have my books to hand but isnt it 16A for 1mm and 18A for 1.5? so even with some correction factors is 1mm not up to the job?

Also surely a ring ding a ding ding in the kitchen is the way forward? wouldn't it work out cheaper, easier and be more suitable for alterations in the future?

10.5A after the itchy snot monkeys have been. still capable of handling most lighting circuits.

1mm fine, but 1.5mm gives real peace of mind, and costs little more. Also gives the bonus of not having to worry too much about voltage drop. Can be a bit fiddlier (is that a word?) to terminate in cruddy cheap fittings etc. - but no more so than using 4mm instead of 2.5mm on sockets - which is increasingly becoming necessary.

Really!! ...Why's that then??

Nowt wrong with 4mm radial 32A breaker for kitchen
