选择配电箱尺寸的方法

1、当电箱只是照明电箱或者小动力时，进线小于10平方时，如果开关位数小于20位时， 开关宽度尺寸加起来再每边加20MM就为电箱宽度，高度为开关高度加40MM，深度为开关大深度加10MM。

2、当电箱为大动力电箱时，或动力照明电箱时，算法基本与上面相同，不过当进线大于10 平 方时，要考虑进线的弯曲半径一级接线端子要预留足够的空间进线，当两排布置开关时，应考虑开关的布线走线。

When the power supply box is only a light box or a small power box, the input line is less than 10 square. If the number of switch bits is less than 20, the width of the switch adds up to 20 mm on each side Height of switch plus 40MM, depth of switch plus 10MM. 2. The Algorithm is basically the same when the power box is a large power box, or when the power lighting box is a large power box, but when the incoming wire is larger than 10 square, take into account the bending radius of the incoming wire When two rows of switches are arranged, the wiring alignment of the switches should be considered.
