    what size cable for 8.5kw shower

    Ive got an electric shower to replace, currenty 8.5 kw on a 6mm cable. Is it dumb to install 8.5kw on 6mm, im sure i used to do this years ago without thinking too hard about it. A quick bit of research recommends 7.5kw max rating. what would you do? Rewire for 10mm too expensive. Cheers.
