I understand that I must have a 5KW double pole switch for a demand under-sink water heater, and that it must be within 2 meters of the device. But can the switch be in the same under-sink cupboard as the heater, or must it be visible and easily accessible?
Lastly, the consumer unit has an RCD, must the circuit be on a 30ma RCD?
Many thanks,
