Correct wire used at last

[Simon Mason]

After suffering several burnouts by using stranded 2.5mm cable for my 8.5 kW sauna, I finally used 50A 10mm cooker cable and have solved the wiring problem.

Good job I don't do it for a living.

You're lucky that the cable was all that burned. You could have been in need of a new house!

Can't you spot attention seeking behaviour when you see it?

Why not?

It's piss easy to do it right first time.

[Simon Mason]

I have just bought a spool of 8mm as the 10mm was too stiff. Up and working again now.

[Tim Lamb]

Oh. Right, I happen to have this chalet bungalow needing a full rewire...

[ARW]

Of course you have!

[Andy Burns]

Must be WF125 coax.

[James Wilkinson Sword]

There's an easy rule of thumb. 1mm takes 10 amps. So 2.5mm takes 25 amps. Your sauna needs 34 amps, which is more than 25.

The 10mm cooker cable is actually capable of 100A.

(Assuming you're talking cross sectional area, which is what they're sold by).

[Simon Mason]

Before I boxed it up - grey is 8mm.

[dennis]

It might be 4mm2.

[Judith]

You need to take care that you don't kill yourself.

[ARW]

Or 6mm.

But not 8mm

[ARW]

Try 64A

[Simon Mason]

My mistake - it is 2x6mm2 + 2.5 mm2.

[Simon Mason]

God can't let me die until I have finished writing that book - I am up to 8JAN14 now.

[ARW]

And why not a proper junction box?

[ARW]

Crack on then.

You could have fitted a double socket in the time it took you to make that post:-)))

I'm more than happy to lend a hand but *skilled* men seem very protective of their work opportunities.

As a matter of interest, am I going to be laughed at if I want to run cables in ducts at ceiling level and through/over soffits rather than have sparkies drilling endless holes through structural timbers?
