Our Electric showers are available in a range of power ratings – please find the minimum fuse size each one requires when fed with a 230/240V electrical supply:
7.5kW 32 Amp supply fuse
8.5kW 40 Amp supply fuse
9.0kW 40 Amp supply fuse
9.5kW 40 Amp supply fuse
9.8kW 45 Amp supply fuse
10.8kW 45 Amp supply fuse
Unfortunately, we can’t advise on the required cable size for any of our Electric showers due to electrical safety legislation.
Instead, you’ll need to ask a Part P registered electrician to assess your installation. Please note, in addition, any electrical installation must comply with British Standard 7671.
