4mm ring final circuit

I put funny iMoji , due to the lack of a groan imoji.

Doe that count as a dad joke?

Thanks for that

A 4mm ring is easy to wire, just use 35mm boxes and if anything you can dress the cables in nicer than with 2.5 because it's stranded and more flexible.

All the 2.5 I have picked up over the last few years has been stranded? but I do tend to use the same wholesaler so should not be surprised.

2.5mm T&E?
Typically conduit wire is always stranded.

 

[Mike Johnson]

Your right pc1966 I have not bought 2.5mm T&E for years, poor old duffer getting more forgetful the older I get and staying in am getting more and more bored. ? is the sun over the yard arm yet?

 

[pc1966]

The sun is always over the yardarm somewhere on the seas!

 

[Mike Johnson]

Thanks for that, bottle now open.

2.5mm T&E?

2.5mm2 T and E is not your go to conduit wire.cable though is it?

 

[Mike Johnson]

Nope.

So what would the OCPD rating be for a 4mm ring?

I'd say at least 40a Alan, possibly even 45 ? You'd have to calculate it based on circuit length and insulation etc.

 

[Dave OCD]

I didn't know it existed Mike ! I thought that ever since the old 7/.029 equivalent was phased out all 2.5mm T&E was solid cores. Every day's a schoolday eh ! ?

I’m just being lazy Dave, wondering if there was a standard figure that is generally used as per a domestic 2.5 RFC. 4mm RFC would therefore offer quite a bit of resilience in a larger kitchen with more juicier appliances. ?

 

[Dave OCD]

It would Alan, but with the ever increasing amounts of insulation specified in buildings maybe it'll become the standard RFC size one day ?
