The circuit breaker switch in the household distribution box depends on the area of the owner's house in the community. There are 5/6 circuits for ordinary single apartments, 7/8 circuits for small apartments, about 10 circuits for large apartments, and more for villas. However, no matter how large the area is, the criterion ◎ of the circuit breaker is fixed. Let's take a look at its configuration

1、 The bedroom hanging air conditioner, because the bedroom of commercial residents is relatively compact, uses 1.5p to 2.0p air conditioners, and the circuit breaker can choose 16/20A air switch or leakage protection. Just a few circuit breakers in the bedroom

2、 The living room air conditioner is a floor ☆ type cabinet unit, usually a 3p air conditioner, with a power of about 4kw. The circuit breaker or leakage protector can be selected at 25A

3、 Lamps can be divided into two circuits here, one for general lighting, and 10A air switch circuit breaker can be used. The other circuit is used for toilet lighting (including Yuba), and 16A air switch circuit breaker can be selected

4、 The kitchen socket is basically a high-level socket. As there are many kitchen appliances, which use 4 square meters of wire, the allowable current is about 30A, so the 32A leakage protector can be competent

5、 Toilet socket, due to the existence of electric water heater, 4 square meters of wire is also appropriate, and 32A circuit breaker is used for leakage protection

6、 The common socket adopts one circuit in many regions, and the common circuit breaker is about 20A. However, the developers may have thought that the lack of a single circuit has turned into a circuit control similar to that of hotels. That is, each bedroom socket is controlled by a leakage circuit breaker to ensure that they will not disturb each other and are easy to maintain.

7、 It is recommended to add over-voltage and undervoltage self resetting circuit breakers. The surge protector depends on the size of the electrical box. If the hydropower device is also recommended in the early stage

8. If it is a loft or a villa, it is recommended to add an additional electrical box on each floor. Each floor is controlled independently, and then the circuit is in phase with the following points
