11 when fitting the heater sufficient clearance should be allowed so that the element is not covered by the sludge or deposits which may settle on the bottom of the tank. Voltage from other devices with ineffective ground connections may pass through the heater ground connection if it is of lower resistance than the original device.

Immersion heater element wiring diagram. Stray voltagecurrent from other sources entering tank through heater ground. It shows the components of the circuit as simplified shapes and the capacity and signal contacts along with the devices. Heating elements are basically in series on single phase power. How to test a water heater element duration. Three phase ac heater circuit where line voltage and. Single element water heater diagrams now here i design another diagram for single heater element water geyser in which i shown only one element wiring.
Element in at the top two elements different lengths one thermostat two cables coming in so each element separately switched but one neutral cut off not connected and the longer of the two elements does not obviously have two terminals. Single phase ac circuits where line voltage and current do not exceed thermostat rating. 12 the thermostat or cutout if fitted and offset in the heater should be at the top side of the element bundle. Immersion heaters are usually rated at 3kw which under normal circumstances would qualify them for being wired into a ring mainhowever because immersion heaters can be left on indefinitely taking 3kw from a ring circuit would reduce the circuits capacity immensely so immersion heaters are placed on their own radial circuit.
