hi, my old shower was 8kwand it kept blowing the fuse and it gets extremely hot at the fuse board and slightly melting it. It is wired to a 30amp fuse. It is wired with 6mm cable. It is approx 15feet of cable from the shower to fuse box and it is the only item on the circuit. I got an Electrican out who said that it was wired correctly and that cable should handle it ok. He had talked about requiring the shower but can't get him back out. I changed to shower and found it kept blowing the fuse and still slightly melting to fuse holder. I found if I put the shower on Eco mode it was ok but now it has finally blown the fuse after 4 months and was really hot at the fuse box. Do I need to change the cable to 10mm and/or put a bigger fuse in the fuse box. I am great full for any suggestions to try. Thanks
