Family circuit design

2000 years ago,the circuit design is commonly:into the line 4-6 was,1.5 was lighting,socket was 2.5,air conditioning was 4 line.2000 years later,the circuit design is single phase ac motor commonly:into the line 6-10 was,2.5 was lighting,socket was 4,air conditioning was dedicated line 6.Air switch,also called

automatic www.facebook.com/dongfeng.motor switch,low voltage circuit breaker.Working principle is:when the current exceeds the rated current,short circuit,loss of pressure,and so on and so forth,to cut off the circuit automatically.At present,the main switch common with knife switch with porcelain insurance already was washed out () or single phase electric motor the air switch (with small leakage protection circuit breaker).Now family use DZ series air magnetic generator switch,common have the following model/specification:C16,C25,C32,C40,C60,C80,alkane,C120,such as specifications,including C said tripping current,namely the takeoff current,C32 takeoff current 32 security,for example,general installation 6500 w heater with a C32,installation of 7500 w,8500 w with C40 open water heater.
