Ao Smith Electric Water Heater Wiring Diagram – In the range of water heating and thermostat wiring, we offer continuous, i.e. simultaneous wiring of dual heating elements (9000 Watt (4500 Watt each)) and 240 V and 230 V electric water heating thermostats. You can see the characteristics of 240 V. installation of non-synchronous water heating lines.
As mentioned earlier, synchronous (continuous) and non-synchronous (continuous). In short, thermostats and heaters operate simultaneously regardless of whether they are powered, but in non-continuous (non-synchronous) mode, the upper temperature turns off when the work is done, and the lower thermostat and heater turn on automatically. due to wiring configuration.

In this post, we present a 9kW dual element (4.5kW heater each) with AC 240V and 230V power supply, thermostat and heating element for continuous operation, that is, the thermostat and heating element will work at the same time from because they receive a separate power supply. supply from the main distribution board.

For the 9000 watt simultaneous water heater wiring, we used the red and black wires as Line 1 and 2 for 240V AC, and Line and Neutral for 230V AC.
Both wires from the main board 120V/240V are connected as power to the thermostat and heaters. L1 connects to the left side of the upper and lower L3 thermostats through a 50 amp fuse and 45-50 amp safety switches. Connect the same power supply to the lower thermostat and heater, then the same breaker and switch. Instead of one 50 amp breaker, you can have two 30 amp breakers for the two thermostats and heaters.
Terminals L4 and T2 of both thermostats are connected to the upper and lower heating elements. In the case of a single breaker (50A), a number 6 wire can be used, while in the case of two separate, each 30A breaker, a number 10 is suitable.
The circuit diagram below shows a 9,000 watt water heater connected to both a thermostat and separate two-pole 30-amp batteries for simultaneous operation.

The permanent wiring of a 230V single-phase water heater is the same as described above for 240V, the only difference being that the L1 and L2 lines and the neutral wire are marked.
That is, a 50A breaker with a 240V supply can safely handle 9000 watts. Assuming a value of 80% for perfect operation and future loading, then:
This means that the system can safely handle a load of 9.6 kW, where the power of our heaters is 9 kW.
Note: The red color indicates the line or phase wire and the black color indicates the neutral wire in the above figures. Follow local wire color codes, ie IEC or NEC.

In our Electric Water Heaters and Thermostats Wiring and Installation series, we show you how to wire and wire for a 240 VAC single-phase (US) non-continuous (non-synchronous) water heater and a two-element thermostat. sets up ) and single-phase 230 V AC (UK/EU).
As we have already discussed about continuous (simultaneous) and non-continuous (non-simultaneous) options. With synchronous wiring, both water heaters work simultaneously, while with non-synchronous wiring, only one heater works at a time, and the second one is “ON” when the first one finishes its heating operation and is disconnected from the power supply. make a. automatically fed by thermostat wiring configuration.

In this post we present a dual element of 10 kW (each heater 5 kW) with AC 240 V power from a 120/240 V main panel and a dual element of 7 kW (each heater 3.5 kW) 230 V for AC and show non-stop work. 240 V AC thermostat wires, meaning only one heating element will work at a time.
As in the previous schematics, the upper thermostat is connected to a single-phase 240 V AC outlet with a 30 amp outlet. The wire (L1) is connected as the hot wire to terminal L3 on the right side of the thermostat. Two wires (blue and red) go from the L4 terminal of the thermostat to the first end of the upper and lower heaters, while the T4 terminal of the upper thermostat is connected to the 1 terminal of the lower thermostat, and the T2 terminal of the upper thermostat is connected to the second terminal of the heater. . Finally, terminal “2” of the lower thermostat is connected to the second terminal of the lower heating element.
Non-synchronous operation of the thermostat will automatically disconnect the upper heating element and connect the lower one after successful operation. The diagram below shows it in full.
Since there are two heating elements with a power of 5000 watts, the total power rating of this heating element is 10,000 watts. The breaker and switch sizes are used for half the total power, i.e. 10 kW, since only one cell is operating at a time.

Now for 240V AC, a 30A breaker is suitable for both size 10 wires, which are followed by the following calculations.
Another way, the safe limit of current draw is 80% (0.8), so 30A x 0.8 = 24 Amps, which is safe to load.
Therefore, a 30A circuit breaker is suitable for overcurrent protection in the case of a 5 kW, two-element, non-continuous water heater for 240 V AC.
The other 7kW (3.5kW per heater) has the same wiring as the 5kW thermostat, although it uses a 20A single-phase transformer at 230V AC for operation. Note that these switches are not suitable for two wire 240V supplies.
