Things done by habit that you have to think about

[Scott Jacob]

Just sitting here and thought of this. New combi boilers. What size cable do you run for them? Been putting them on a thier own separate radial circuit for years but I automatically run 2.5mm but I guess a 1.5mm is fine these days as only a 3amp is needed on the old fuse spur. Anyone else install things out of habit that’s now over kill?

Always 2.5 for any power circuit

Just in case for example home owner moves boiler can then turn boiler spur into a double socket

Still can if it's 1.5mm depending on breaker size.

I personally don’t like 1.5 on a B16

Why not?

C16 then

 

[Dustydazzler]

I know it technically complies but i think changing the device to a B20 is my ‘preferred’ option if converting a boiler supply to a double 13a socket

Just my preference

20Amp radial socket circuit quite correct Dd. Standard socket radial circuit isn't it?

 

[Risteard]

not sure you can run 1mm for a non lighting circuit

I am sure.

You can't.

 

[Risteard]

I've never wired central heating in 2.5mm^2 - there is absolutely no point when the entire system is typically fed through a 3A BS 1362 fuse anyway.

I have always wired them in 1.5mm^2 and see no reason to change it.

A B6 or B10 and all's k00l.

How dare you...
I put the seat and lid down after use...

Just out of intrest has anyone got a souce for where it says 1mm cant be used for a non lighting circuit.

Never done it, just intrested. Tell me to look myself if you wish.

 

[Pete999]

souce

SOURCE you have fat fingers as well Chris?

I have a horrendus keypad on my phone mate. My spellings gone to carp because of it.

Think someone quoted the reg earlier.

I put the seat and lid down after stretching cling film over the pan...

corrected that for you.

Not that I'm bored or anything... but it's on Page 144 of the 18th

Litrelly never installed a piece of 1mm cable. Always 1.5mm.

Oh O'reilly. you need to live a little, life's too short.
