I have an old 8.5KW Triton electric shower for the last 10 years which needs replacing. I have bought a new 8.5KW electric shower and I'm hoping someone can help me.
I read the instruction manual of the new shower and it recommends a 10mm cable and a 40 amp MCB for showers over 8KW
I checked the set up of my old shower and it was wired with 6mm cable and the fuse box has a B32 amp MCB. The shower is approx 4m away from the fuse box.
Even though my old shower has worked fine for the last 10 years, can someone please advise me if the correct cable and MCB was installed from day 1??
Is 6mm cable and a B32 MCB safe for a 8.5KW shower??
