Question: Should I install an isolating switch for an electric shower?
If yes, where should it be positioned?
As the consumer unit is back-to-back with the shower, could it be fitted there?
Answer: Yes, it must be on an RCD protected circuit.
The shower should have a double-pole isolation switch - either a 50A ceiling mounted pull cord switch within the bathroom, but outside the zones, or a 45A wall-mounted switch outside the room.
The main reason for this requirement is for maintenance purposes.
Note that, as a manufacturer we can only forward details of our products and it is down to the contractor who is wiring up the installation to make the correct choice in terms rating, positioning and use, so please refer to BS7671:2008 (17th Edition of the Wiring Regulations) for further guidance on this type of installation.
