Since the supply voltage is 120V, hence it draws the maximum of 25 amperes current (Ohm’s law: I = P/V). The rating of the water heater element is 3kW. The earth or ground “G” is connected to the junction box of the water heater. On the other hand, the neutral (N) is directly connected to the second terminal of the heating element. In this wiring connection, the phase line (L) from 120V/240V main panel (SP breaker) is connected to the L 1 screw on the thermostat and then leaving the T 2 terminal which is further connected to the single heating element. 120V AC Single Phase Single Element Water Heater Thermostat Wiring Let’s see different wiring diagrams for single element water heater thermostats as follows.

In the first basic tutorial, we will be showing how to wire and install a single element water heater and thermostat for 120V AC single phase (US), 230V AC single phase (EU/UK) and 240V AC two lines US. In this series, we will be showing how to wire different water heaters and thermostats like, single phase water heater, three phase water heater (balanced and unbalanced), continuous and non-continues (simultaneous and non-simultaneous) water heater installation, thermostats wiring diagram with switches and breaker rating. Well, we are not telling a love story here but want to show how to manage the hot water by wiring the hot water geyser and electric water heater wiring installation tutorial.

If this is not the case for you (don’t tell a lie), I prefer speaking the truth “I Love Hot Water Too Much in the Cold and Snowy Weather”. In the shivery and freezing to the bone season, we need hot water instead of her/him. What Uses 220V In A House?ĭifferent appliances require a 220-volt or over the electrical line.Single Element Water Heater Thermostat Wiring Diagram In comparison, a ground wire protects the circuit from instability and other possible problems. It’s also important to mention that a neutral wire is different from a ground wire.

This wire carries the power from the device back to its origin. What Does The Neutral Wire Do?Ī neutral wire in an electrical setup helps take on the role of completing the circuit. But 10/3 wires can be better options than their 10/2 counterparts for 220-volt setups. Many 220-volt electrical connections require 10/2 wires to complete 30-amp circuits. Since clothes dryers often need over 110 volts to function, these appliances typically need at least 10/3 size wires to prevent overloads and fires. On that note, 10/2 wires often only have one hot wire, which is the hot and neutral wires.

So it can be ideal to use a 10/3 wire instead.Īlso, using the 10/2 wire can be a violation of the National Electrical Code (NEC) 250.140, which mentions that the supply circuit for a 120/240-volt setup should possess three wires. However, you might run into some issues with that size wire. It’s possible to use a 10/2 wire for a clothes dryer.
