breaker.
Where the water heater is permanently connected to the power
supply, it must be able to be separated from the mains power
supply by an additional isolator that disconnects all poles with

contractors, circuit breakers, fuses, etc. on site.
In case of a fault, the safety equipment interrupts the relevant
power circuit.
