UL153, UL1310 SPACING?
UL 153 是uninsulatedlive parts and metal is capable of being grounded:throug air 6.4, over surface 9.5mmUL1310 是live partsand metal enclosure120V 要求6.4mm
现在有一LED 灯具,里面有个UL1310 驱动器,电路板有麦拉片绝缘,然后最外面是金属ENCLOSURE 与电源地线相连。
问电路板中L, N 到地线是不是要按UL153 来,还是按UL1310 判断?
按UL1310 判断 驱动器有它的专用标准
