The height setting of kitchen socket should consider safety, convenient operation and beauty. Generally speaking, it is recommended to keep the height of the kitchen socket from the ground between 150cm- 180cm. This height can ensure that the socket is not easy to touch when operating the countertop, and it is also convenient for the use of electrical appliances.

Of course, the specific height setting may be adjusted due to personal preferences and differences in kitchen layout. Here are some suggestions:

1. Ensure safety: In order to avoid the danger of electric shock, it is recommended to set the socket under the operating table. If you need to use electrical appliances on the dining table, you can consider installing a socket with switch control to reduce the risk of direct contact with the power supply.

2. Consider the use demand: When planning the socket location, consider the use demand of kitchen appliances. For example, for small household appliances that need to be plugged and unplugged frequently, the socket can be set at a lower position for easy operation. For some large electrical appliances that are fixedly installed, the socket can be set in a higher position.

3. Keep it beautiful: when setting the socket, make sure it is in harmony with the overall design style of the kitchen. You can choose a hidden socket or a socket with a cover to keep the kitchen clean and beautiful.

4. Consider the layout of the kitchen: According to the layout of the kitchen, the position and height of the socket can be flexibly adjusted. For example, in the area near the sink, the socket can be set slightly lower to avoid water splashing on the socket, which may cause potential safety hazards.

Please note that different brands and models of kitchen appliances may have different power requirements. When setting the height of the socket, be sure to follow the instructions of the relevant electrical appliances and ensure the safety of the power cord. If in doubt, please consult a professional electrician or designer.
