RFC Cable Size Question!

[Paul.M]

Ok it is unlike me to ask a question like this but it has been a very, very, very long day and I'm questioning my own plans. Basic question really :sweatdrop:

Customer is converting a very large basement room into a kitchen. I've been rushed in at the last minuet whilst the builders are putting up stud & plaster boards on the ceiling (basement = concrete floor and 6" thick Yorkshire stone for the ceiling + joists for the rooms above).

There is a 4mm t&e radial feeding this room which has tested out perfectly, r1+r2, IR & Zs are all great and no worries about continuing using this cable.

Q:- Is there any reason why I cant install a RFC using the 4mm as the first point feed to the new RFC and continuing the RFC in 2.5mm???

Brain fart. One of those days when you question yourself lol. I cant see anything wrong with it but I would love an opinion or two from you guys :rolleyes2:

A man of your calibre asking a question like that!! You are making me doubt myself now, haha! Can't see anything wrong with what you say. I would be tempted to continue in 4mm and have a 32A radial, then run some 2.5 back to the CU (which you are planning anyway) and have another radial too (spare ways permitting).

:iagree: But he's a tight yorkie, that'll mean another breaker. Probably record the csa as 3.25mm and cpc as 2.0mm

Don't be starting the war of the roses again.......! You're making it start to sound like the recent lollipop cct thread now with talk of 2mm CPCs !

I would be inclined to continue the 32A radial as it is

Yeah same here but I got a call from the builder (friend) at 3pm saying his sparky has let him down big style and cant work on this house, can you come tonight after work (after my day job atm... suby NHS install) and put cables in so we can board tomorrow?!?!?

Only had enough 6mm in the van for the cooker circuit or the RFC would have been thrown in at 10 o'clock at night! No 4mm, only 2.5mm, hence the question.

Ran out of 1.5 twin for the spot lights halve way through so used 3 core 1.5 instead! The next electrician in ten years time doing an EICR will be laughing his socks off when he drops a spot form that ceiling :1eye:

mein gott, that's akin to smokes without nicotine or quorn meat free sausages.

The ring in my living room is just like that, half in 4mm and half in 2.5mm. I didn't install it though, a bit pointless and a waste of copper but electrically sound!

My only concern would be the 4mm stranded and the 2.5mm solid at the first socket, double the 2.5 over.

Aye, fair do's Paul...but I'm not drinking that ^^ **ss, even if your paying .

I bet Big Yin wouldn't either.

I had the misfortune once whilst driving some mates on a darts night. If someone had told me it was sugared turnip juice rinsed through a sodastream I would have not been surprised.

Becks blue is the only one I have found that actually tastes of beer.

Are you planning on wiring this as a lollipop circuit.? Whats the install method of the 4mm.?
