  • So why hasn’t it been tripping already?

    240x30=7.2kw.

    Do you do 240 or 230? Either way it doesn’t add up.

  • It's only using maximum current for a short period of time when the shower starts and breakers generally allow a little overcurrent before tripping. It's also possible that the 8.5kw figure has a bit of marketing guff involved.
