Home / Where is the main switch of the three-level distribution box
The main switch is often located at the top, allowing users to quickly shut off all circuits in an emergency. Electrical equipment is installed under the switch box, forming a three-level distribution. "Two level protection" mainly refers to the use of leakage protection measures. A distribution board (often called a switchboard or panelboard) is an assembly that receives power from the main supply and distributes it to subsidiary circuits. It also provides protection against overloads, short circuits, and earth faults using circuit breakers and protective devices. (1) Power distribution from the primary main distribution board (distribution cabinet) to secondary distribution boards can be branched; that is, one main distribution board may supply power via multiple branch circuits to several secondary distribution boards. 5P-20A two-phase leakage switch Electric water heater 8000W+ washing machine - 60A two-phase leakage switch Socket switch 16A The main.
