several group number, then with b ± a, =c,c is is methyl b two vertical box between of accurate size线开关应装设漏电保护器。在用电设备漏电、人身触电时自动跳闸切断电源，从而保护人身和用电设备的安全。
四、使用三孔插头的电器设备的外壳要可靠接地。一定要配三孔插座，并接好地线，以防外壳带电发生触电危险。

Per-2~3 measurement, such as proceeds of c values are equal and equal to the design value, then the vertical installation accurate. For example a, b, and c valueswhile on horizontal vertical errors for measurement, General in iron angle code bit at measurement level points grid errors, specific method is from baseline to methyl vertical box center line distance for a,, to b vertical box distance for b, list can measured
