hi
I'm upgrading to a shower with 9.6kw power rating at 230v, my existing shower is fed by 6mm cable and when installed, a seperate consumer unit was used which contains only one fuse, the unit is fed from the meter and is marked as 45a on the unit but contains a 30A cartridge fuse.
I am going to change the cable to 10mm, do I need to and if so can I change the cartridge fuse/holder to 45A in the existing unit or would I be better changing this unit for an 45A MCB or RCD ?
