Cable size for showers

Can't recall what the clipped direct rating is but 8.5 on 6mm with a 32/40 is fine.

hi.. providing there is no insulation involved and the whole run is clipped direct or in free air..6mm and 40a mcb will be ok up to and including 8.5kw..any bigger and10mm is advisable..as im sure you are aware there are many other factors that need to be considered when selecting size..but on average your 6mm is sufficient 4 most installs off this size..

 

Just auto whip a lump of 10mm in and be done with it. You will be glad you did..

 

I try & stay clear of 10mm, Bit of a problem getting it into a pull switch at the same time as keeping the outer sheath in the box as well. I usually use 6mm for up to 8.5kw. It does not however allow for upgrading to a higher rated shower later on. I reckon 8.5 is enough power most of the time.

 

Those Crabtree 50 Amp DP have got nice terminals Wal.

 

Hi all,

I thought that on 6mm a 32A breaker 7.2Kw would be your max size shower, using anything bigger would it not mean you would need to go to a 10mm cable and larger breaker?

Appreciate other factors, insulation, grouping, clipped, distance etc.

Thanks.

 

Don't worry about it Ian. Just use the existing 6mm cable for the 9kW shower. Your customer won't have the slightest problem with it - unless he's rich enough to spend all weekend in the shower.......

As long as the cable isn't surrounded by insulation and not an excessively long run, 6mm will be fine on 9.5 Kw.

 

I don't belive that people would use 6mm for a shower unless it is pre-existing.

Ok 2 or more years back yes..but now? No Way.

 

If I went back into re-furbs and stuff and had to stick cable in for a electric shower, then it would be 10mm and nowt less..

 

why

if it is not required seems a bit untrained to me

cheers

put in the right gear at the time of installation

I do know though Mr Sillys..

I state again that in a new install then I would use 10mm. What other people do is there business..and they have there own modus operandi.

Its no joke if a customer wants a more powerful electric shower after the install. What you going to say?..Sorry thats the max as the cable wont take it..try saying that to one of the Hampstead lot and see where you get.
