The master switch must be 2P specification without leakage, so as not to turn off the master switch normally in case of leakage.

independent mesh

Independent circuits should have leakage, such as circuits in kitchens, bathrooms and sockets. Because the air in these places is humid, sockets and power supplies are often used, so using a switch with leakage can reduce the risk of leakage.

Lighting, air conditioning and other electrical appliances

Lighting, air conditioning and other electrical appliances do not need to use switches with leakage, but can directly use DPN double-in and double-out circuit breakers to avoid leakage of air conditioning and other electrical appliances and affect the normal operation of other places.

Distribution box specification

Choose the specifications of the distribution box according to the household electricity consumption. If the household electricity consumption is large, a distribution box with larger capacity can be configured. If the household electricity consumption is small, a distribution box with low capacity can be configured.
