Q3:  I live in Reading and am going to replace my electrical shower. It is 8.5kw Mira. Can I have a 9.5kw shower?


A: Maybe not. You need to check a couple of things.

First. Is the cable 6mm2 or 10mm2? 6mm2 can only carry 8.5kw shower. 10mm2 can carry upto 10.5kw.

Second. Check the circuit breaker for the shower. If the circuit breaker is B40 only you need to change it to B45.

Third. The electrical shower should have a double pole switch. If it does not have one then it should be added.

Finally if the circuit does not have RCD protection in the consumer unit then the consumer unit should be updated or a RCD should be installed in the shower circuit.
