    "I assume you have changed the shower? it depends if the cable has been sized for 30A taking into account length of run and correction factors when originally installed, a new calculation will have to be carried out to determine if the circuit breaker can be increased"

    "Hello, in a 10mm cable you can install up to 50A. But make sure is 10mm and not 6mm because on a 6mm you can go up to 32A"

    "Hi, normally you can without any problems, however, this work should be carried out by an electrician as you are changing the characteristics of your fuse board. The amount of power that the cable can carry will be reduced if it is under insulation as an example."
