How to wire the electric heater?Kaitong Electric answers you

As a common heating element in industrial equipment, the correct wiring method of electric heaters is crucial to the stable operation of the equipment.So, how to wire the electric heater?Let’s explain in detail below.

1. Prepare tools and materials

Before starting wiring, we need to prepare the following tools and materials:

• Insulating tape

• Wire strippers

• screwdriver

• Electric heater body

• Power cord

2. Understand the wiring principle of electric heater

Electric heaters usually use three-phase AC power supply, and the wiring methods are divided into star connection method and triangle connection method.The following is a brief description of the two connection methods:

• Star connection method : connect the phase lines of the three-phase power supply to the three heating elements of the electric heater respectively, and connect the neutral wire to the common end of the electric heater.

• Triangular connection method : connect the phase lines of the three-phase power supply to the three heating elements of the electric heater in turn to form a closed circuit.

3. Electric heater wiring steps

Here are the specific steps for wiring the electric heater:

1. Strip the insulation layer on one end of the power cord, and the length is about 10 cm.

2. Connect the stripped power cords to the corresponding terminals of the electric heater separately to ensure a firm connection.

3. Use insulating tape to insulate the connection to prevent leakage.

4. Connect the other end of the power cord to a power outlet or distribution box.

5. Check whether the wiring is correct and ensure safety.

4. Things to note

During the wiring process of electric heater, the following points should be paid attention to:

• Make sure the power supply voltage matches the rated voltage of the electric heater.

• When wiring, be sure to cut off the power supply to ensure safety.

• During wiring, avoid damaging the electric heater body.

• After wiring is completed, conduct a trial operation to check whether the equipment is working normally.
