Does the induction hob need to be grounded?
The induction hob is an electrical device, and of course, before leaving the factory, the products have been thoroughly tested for electrical leakage. But no one can confidently assert that the hob will never experience electrical leakage during installation or use. Even if it is a high-end imported induction hob, it is still safe.
Electrical leakage from the induction hob may not be caused by the hob itself but by other factors and causes. For example, errors during installation, choosing non-standard wiring, mistakes in wiring the induction hob, or due to the hob being old, installed in damp places, or insects biting the wires…

Moreover, the electrical supply that Vietnamese households are using has a voltage of 220V, which is quite high and dangerous if this current flows through. According to scientific evidence, a voltage of 40V can cause death by electric shock upon contact. Therefore, using electrical appliances requires utmost caution.
Customers often ask whether the induction hob needs to be grounded. According to Kocher, for single induction hobs, especially those used in restaurants for hot pot, this solution is not suitable as they often move the equipment and only use Common types of sockets for induction hobs. However, for double induction hobs that are fixed for cooking, grounding the induction hob is a necessary solution.
- With 2 cooking zones or more, the induction hob needs to be grounded because this product line has high cooking power and consumes a large amount of electrical energy. Grounding will help ensure the cook’s safety, avoiding electrical leakage phenomena.
- Grounding the induction hob reduces the resistance of the hob to be lower than the resistance of the human body. In case the induction hob experiences electrical leakage, the current will flow to the ground, and the user will not be shocked or endangered when touching or coming into contact with the hob. Thus, it avoids risks when the induction hob has electrical leakage.
- Grounding the induction hob is necessary because the cooking area often has water, which is a very good conductor of electricity. If the induction hob leaks electricity and comes into contact with water, it can pose unpredictable dangers to the cook and other family members.
- For induction hob products with metal casings, or old induction hobs that are rusty and have lost their insulation, they can also pose a danger to users. If the electrical source is exposed, the casing of the induction hob can become a conductor.
- Grounding the induction hob does not cost much or take much time; do not compromise your safety and that of your family members due to negligence.
Guide to grounding the induction hob simply
1. Grounding method for induction hobs – houses
You should mark the grounding wire and the wire connected to the casing of the induction hob. Moreover, the intermediate wire connecting between the casing of the induction hob and the electrical device must have a layer of safe insulation.
2. Grounding method for induction hobs – apartment
#1: Instead of driving a metal rod into the ground, plug it into the metal frame of the window or door that has a metal part. Or simply plug it into the floor or wall with a minimum depth of 10cm.
#2: If you do not want to apply the above method, you can prepare a plastic bag of soil, plant a tree in the soil with a depth of more than 10cm, and do it similarly to method 1. Below is an illustration of how to ground the induction hob that you can easily follow.
In addition, for professional repair technicians, alongside protecting the machine casing, they will also periodically check the How to check the power module IGBT inside the circuit board to detect early risks of short circuits causing leakage to the cooling system. Wish you success in your implementation.
