1.5mm SWA, Acceptable or bad practice ?

[pevvers]

So would I, but I would actually make it an RCBO instead of an MCB.

But a 1.5mm would be fine,

Hi,
Personally I would use 2.5 backed by a B-type mcb of 20a

hi ice,
dont start pevvers off again, weve only just agreed to disagree lol

 

[pevvers]

Heheh....

I've only just noticed that you'd editted a few of your posts, and I was contemplating starting again.

But there will be other times!

I'm with you on this one pevvers..

No one has yet given a valid reason and explained why they wouldnt use 1.5mm SWA on a 16a MCB, or even 20A MCB for that reason.

not edited, im just too quick with the return button so post goes on before ive finished

never had that problem with my trusty typewriter

i look forward to the other times, its good to talk

hi sid,
dont need to explain myself, because thats the way I do it. lets leave it there shall we

In all honesty, If I was running a Radial socket outlet in my own House it would be in 4mm and it would not be protected by a 30mA as they are a Pigging nuisance although if it was for anyone else it would be protected.

Even if it was for external use as was stated in the OP?

Fair do's if you wanna use 4mm though, whatever floats your boat I suppose, seems an extra expense for no apparent reason to me though.

4mm radial in SWA seems way over the top.
2.5mm is well within the regs and calcs limits.
If you wanted to i think1.5mm Seems perfectly acceptable, there would still be no overloading issues.

I think it's just me and you Sid....

Ha ha, Seems to be..

Who else wants to be in our "1.5mm SWA GANG" ?

 

[acvc]

Surely it all comes down to design current less than protective device rating less than current carrying capacity? If that's the case, then it's ok with the Big Red Book.

Count me in!

Viva la revolución!

dont dissagree with you, I would also install 2.5mm, its just that the customer has huge amount of 1.5mm and wondered if i could use it.

Use it! Save yourself some money!

As said earlier, if its protected then theres no problem....
If your really worried, make it a ring if theres no shortage of cable!
