To RCD protect or not to RCD protect (a hopefully simple question)?

[Martin Angove]

Now you've confused me >:-/

My problem was with "Z" who was apparently saying that whereas you'd normally use 2.5mm cable on a 16A circuit, if it were Pirelli cable then

1.5mm is sufficient. TBH 1.5mm T&E should be ok for 20A under method 1 whatever the manufacturer.

I threw MICS in because I am aware (Table 4J1A) that it has a somewhat higher current-carrying capacity than 70C PVC T&E and wondered if he had been confused. I might go so far as to allow 90C cables a higher capacity (more tables)... but there are plenty of manufacturers other than Pirelli producing those :-)

Isn't LSF cable rated exactly the same as PVC of similar construction? Never used your Flame Shielded stuff, though I have seen it, but I can't find it in the regs either. Does it come under MICS?

Hwyl!

You're actually better treating the cables as being the same as PVC T&E Martin. For safety sake on the circuits you're designing anyway, it's best to use the tables for the plain T&E cables.

What does that mean?

In the trade Pirelli refers to cable of a fire retardant nature such as FP200/gold, Fire-tuf, fire-tec and their ilk.

Mineral Insulated (MICC) you mean?

No, I'm not confused.

Yes but generically it is referred to a Pirelli whether Pirelli, AEI, Delta or anyone else makes it.

Yes, if you are referring to it's only having an insulant with low smoke and fume properties with nothing else different. I avoid PVC/PVC cable if at all possible particularly that T&E Brits seem so keen on.

What is flame shielded? Pirelli you mean? :-)

? My regulations are in the vehicle. Pirelli.co.uk/fp has datasheets on FP200 Gold and FP Plus

Fun or merriment according to my dictionary

Welsh, please - note the initial capital :-) Cymro Cymraeg hefyd.

It's a sign-off I've been using for years and one of these days I'll probably get bored with it and find another one, but it'll do for now.

As well as Andy's explanation of "fun or merriment" (but much more than that) it is also a contraction of "hwyl fawr" which is the Welsh equivalent of "goodbye", i.e. akin to "'bye".

If my Welshness offends you, please feel free to ignore me. It's a trick the English have been using with the Welsh for some centuries and which we are only now escaping from.

Actually, half my ancestors aren't actually Welsh at all, though they are at least Celts - the Angoves (an Gof, the Smith) are Cornishmen. Except for the South Africans, Canadians, Americans and wine-making Australians ;-)

Hwyl!

Sorry, I don't tend to do capitals, in the same way I don't often use full stops at the end of an email
