The refrigerator is too short. I want to raise it from under the refrigerator. Can I use a wooden box? What are the precautions?

Grounding is some electrical components in the refrigerator, such as temperature controller, heating wire, compressor and so on. In fact, the motor is running, which will accumulate induced electricity on the surface of the refrigerator. For safety reasons, grounding measures are adopted. The refrigerator has three plugs, the longest is the ground wire, and the socket corresponds to the ground wire. Therefore, the use of wooden cases will not affect the grounding of the refrigerator. Of course, you must ensure that your socket has a ground wire before you can use it safely. I wish you a happy life.
