This question is regarding Triton T80Z Fast-Fit 8.5kW Electric Shower (White/Chrome) - SP8008ZFF

Gainsborough Monarch Plus 4007 (1993) replacement

My Gainsborough Monarch plus shower rated at 7.2 kw has just gone faulty after 22years sterling service. Footprint of Triton t80z seems that it can be fitted as direct replacement without making mess of wall tiles, however Triton t80z rated at 7.5 kw is this likely to present any difficulty or should current cabling be adequate i.e. difference between 7.2kw and 7.5kw?

If your existing shower was installed with 6mm wiring (as it should have been) then fitting another shower (even up to one of the 10kw units) to the existing wiring should be no problem, depending on the length of the run off cable and how the cable is installed.

Here is a table that allows you to work out what you can do with the existing wiring, make sure you fill it in accurately as this can make a large difference to the eventual calculation.

You may also have to change the fuse

Up to 8.5kw 35 Amp fuse

Up to 9.5kw 40 Amp Fuse

Up to 10.5kw 45 Amp Fuse

If you are even in the slightest unsure about any of the above then please contact an electrician.
