Hello,
I am after some advice if possible from those in the know. My current shower has just died (Only supplies cold) I would like to replace it but with a higher power unit. The current one is a 7kW unit. The shower is fed from the houses main CU which has a main trip fuse of 100A and the shower feed is connected to a 32A MCB on the RCD side of the CU. The cable runs from the CU through the wall and then runs up the outside wall of the house wall into the attic. It then goes to the ceiling mounted switch in the bathroom and then through the wall and exits into the back of the shower. The cable used throughout is 10mm in width (measured from the one side of the grey sheath to the other) Total length of the cable from CU to shower is approx 9m. Having read the various posts of questions of this nature if I want to fit a 9.5kW unit am I going to have to have the circuit upgraded? Can this be just the change of the MCB in the CU to a 45a rated one and then replace the shower or am I going to need a separate RCBO ? Also is the cable the correct size for a 9.5kW unit or is this going to have to be replaced as well?
Thanks in advance for any advice given.
