Changing to a 9.5kw from 8.5kw
It is supplied by a 40amp MCB with 6mm cable, can I upgrade to 9.5kw with this supply.
I have read that it is NOT always necessary to use 10mm cable with a 9.5kw shower.
Our 6mm cable length is approx 20 meters.
Thanks
Fitting a more powerful shower to the existing wiring. 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. www.tlc-direct.co.uk/Technical/Charts/VoltageDrop.html 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. |
