My family has been traveling recently. What's wrong with just turning on the light and not jumping? Water heater. Jump when the electric kettle is removed.

According to your question, there are two possibilities; First, the load of your household electricity is too high during the peak period. At the beginning, the capacity you reported to the power supply enterprise was insufficient. I suggest you apply to the power supply enterprise for capacity increase. For details, please pay attention to and bind the public platform of China Southern Power Grid 95598 > My Power Consumption > Business Handling > Business Change > Select Capacity Expansion > Fill in the handling information, manager information and SMS verification code, and click OK. Second, if the installed capacity is enough, it may be that the rated current of your air switch is too small to meet your electricity load. I suggest you entrust a qualified electrician to check it for you.
