Introduction:
LWHG series distribution box is a kind of modularized apperance with small volume industrial electrical box. Based on the advantages of being easy to install, it has excellent strucure and higher performance,and it's widely applied in building electrical distribution system's installation, industrial
electrical circuit and house rebuild fitment etc.
1. For safety reasons, we still add leakage switch to the air conditioner socket.Lighting loop selection without leakage protection, this topic and whether the air conditioning socket need to install leakage, and then the industry is controversial.Residential outdoor types of electrical distribution box structure according to the installation method is divided into closed hanging type, clearly installed and embedded, hidden installed in the two.The main structure is divided into shell, panel, installation bracket, neutral bus row, grounding bus row and other components.
2. The rated operating current of the circuit breaker is 30mA, when the leakage reaches the operating current, whether it is the size of the air switch ampals, the same trip!When a primary leakage occurs, the branch protector and the main switch are likely to trip or trip at the same time. It is also possible that the main switch leakage protection is too sensitive to trip, and the branch does not trip.Although this configuration has the meaning of double protection, it is still inevitable that the main switch trip, practicability is not high, and the existence of the first possible situation.
