Can anyone advise if a twin and earth cable of approx 13mm overall diameter is 6mm or 10mm cable. it supplies my electric shower which needs replacing and i am not sure what kw rating unit I can stretch to?

6mm has single -trand earth conductor
10mm has multi-strand earth conductor

That may be true of today's cable, but going back in history things were different...

The pre-metric "2.5mm" in my house has three-strand earth (and 7-strand phase and neutral - I think it was called 7/029 in the Good Old Days?)

I also have a reel of 6mm Earth cable that has 84 strands - it's a darned sight easier to work than the current 7-strand stuff! Can you still get the more multi-cored varieties of cable, or has economy wiped them out?

Cheers,

Howard

we use stranded (loads of strands) 6mm earth at work. it much easier to work with than the earth with 7 strands
 
The only time we use stranded is for temporary gen installed etc. Big 5 core flexes, 25/35/50mm etc. Call them 'pythons'. Easy to handle, but still very heavy:cool:
