Hi,
Currently my shower is - from looking at the cable externally - on a 6mm cable circuit over about 5 metres connected to a 30 amp fuse. No RCD.
Shower is 8.5kw and I am limited to around 10 minutes of use before the fuse trips.
If I get an electrician to upgrade the cable to 10mm and fuse to 45amp will that work be classed as 'new' and need an RCD?
If so it may be time to replace the CU.
