Replacing shower, what size cable is this

[pody]

Just about to order the parts to renew my bathroom. Though I better check what size shower/cable is there just now. The shower is a trion 8.5 and the fuse in the fusebox is marked ln5945 b45 -so a 45.

I am unsure of the size of existing cable, can someone confirm the size? I have a mira sport max 10.8 ready to be ordered.

Let's hope it's already 10mm²...

it should have the size embossed into it somewhere along it's length.. normally every 2 foot or so.. get up into the loft and trace it back and have a look..

if it doesn't then try the table in the link BAS provided.. 10mm is about 17mm wide, as opposed to 6mm which is about 14mm wide..

Looks 100% like 6mm to me.

10mm has a stranded earth, and the conductors in proportion to everything in the pics indicate to me it is most definantly 6mm.

 

[ColJack]

that would be my guess based on the solid earth wire, isn't it stranded on 10mm?

 

[wingcoax]

Not stranded on the 10mm i use.

Looking at where it passes through the 20mm hole in the metal box I'd say it looked like 17mm across? Which should make it 10mm sq.

It's always best to put a micrometer across the copper conductor, then work out the cross sectional area, if you're not sure.

preferably not whilst live...

Ah... didn't I mention that?

What brand do you use?

In all my career, I've never seen 10.0mm² t&e with anything other than a stranded earth.

Oh and the cable in the picture is 6.0mm²

 

[ColJack]

good, not just me imagining it then?

Not sure I quiet believe that TBH.

What size CPC is in *your* 10mm T+E?

Can you imagine a solid 4mm conductor?

Also need some earth sleeving on those CPCs in the isolator.
Is supplementary bonding in place?
