The isolator switch acts as a switch to isolate both live and neutral from the main supply should someone accidentally switch on the main supply or the circuit breaker fails. Switch off circuit breaker of geyser at main db.

Geyser isolator wiring diagram. The geyser also has to be earthed. This ensures that the person working on the geyser is safe and cannot be electrocuted. Regulates the water pressure inside the. The pcv is typically above the geyser and the cold water flows down into the geyser. Im also interested to know why there are wires running from the stove circuit breaker to the geyser isolator and then to the earth leakage unit as well as a wire from the. An isolator switch is used to ensure that when switched off all current is physically isolated on the line to the geyser when repairs are being done or when a new geyser is being installed.
Switch off isolator switch in the roof. In electrical engineering a disconnector disconnect switch or isolator switch is used to ensure that an electrical circuit is completely de energized for service or maintenance. Should be within 1m of the geyser. These are often just left lying next to the geyser. This was not a requirement on old geysers. Note that water enters cold and leaves hot from above the geyser top look at the diagram below.
There should be a cover over the thermostat and element. This is quite important because it forms an anti syphon loop that prevents the geyser from draining back through the inlet in the event of a water supply failure. This is done to ensure that there is no power supply to the geyser.
