Where does the standard of the power cord length of electric kettle be measured?
First of all, teach you a little common sense of using electricity:1, household appliances are generally single-phase power supply, that is, 220v;2, the so-called single-phase power supply by a phase line L (commonly known as FireWire), a zero line N, a ground wire composition, but also by the phase line and zero line composed of two single-phase power supply;3, some household appliances have required grounding wire, such as washing machines, etc.;4, the so-called ground wire is to prevent leakage of the accident release, in the electrical shell connected to a wire into the ground, now multi-purpose leakage protector.
Standard for exposed length of electric kettle:1, GS: exposed 55-75CM (recommended length: 85-95CM); safety regulations are less than 75CM;2, UL: exposure 60-90CM; CUL/CAS: exposure 90-100CM; safety regulation is greater than 90CM; if CUL, can only take 0.9M.
1, only need to connect two lines, but the line must be connected correctly, if the connection is not correct, you will hear the explosion, or your water can not boil2, you say that one is only two holes connected with the electric kettle, three lines, a red two black, I want you to look carefully, certainly only one black, one red, and one blue line is not yellow green color line.3, the red line is sure to connect, and two, if it is a black line, a blue line, then the black line, and if it is a black line, a yellow green two color line, then the black line.4, anyway, any two lines can not be twisted together
