Upgraded my old 7.2kW shower to 8.5kW. Old fuse was 32A but new suggests 40A in instructions (and Mira helpline). Seems to work (so far) but how do I go about replacing a 32A trip switch for a 40A trip switch? (There is an RCD pull-cord device installed as well.) Nothin obvious, but wil change out if required by whatever means necessary
All help appreciated....
