Anyone competent can install the cable, but the connection to the isolator and the fuseboard must be made by an electrical testing qualified tradesperson and a certificate issued. Whoever installs the cable needs to be aware that any shower above 9.5Kw will require a 10mm T&E cable, RCD protection and either a 45Amp or 50amp MCB or RCBO, most other showers below 9.5Kw can be wired in 6mm T&E cable.
