Hi Guys, I've got an 8.5Kw shower which I need to replace - all good shouldn't be a problem (ha-ha)... I looked at the breaker and its 40amp, checked the cable exiting the box and its 10mm. Great, a 9.5Kw shower will be nice upgrade.
Now the problem is I've just come to fit the thing and removing the old shower reveals a 6mm cable, further investigation reveals that it changed from a 10mm to a 6mm at the isolator pull cord.
So, firstly I'm fairly happy that I can't fit a 9.5Kw using this setup as 6mm isn't sufficient - correct?
Secondly, to my mind I need to replace this (2ish meter) section of 6mm as this current set-up isn't acceptable anyway (as the cable down the line is a lower rating then the MCB) - again correct?
Cheers!
