手里有一个CASE,是一束MINI BULB通过一个Connector接一个CLASS 2的PLUG-IN变压器.小弟有几个疑问,请坛子里的高手帮忙解惑下.' R+ K6 s; D6 A$ j: s
. w* M. c8 a# z2 k* w* D1.UL 588涉及的产品种类有哪几种?因为我接触到的只有DECORATIVE STRING,DECORATIVE OUTFIT,对588了解的不多,象这种接变压器的是否在标准中单独的可以看做一类产品(DIRECT PLUG-IN UNIT)?如果不是,那它算是哪类产品呢?+ m+ }$ @3 E* m8 R6 X

2.这种产品是否需要符合标准117.6的要求?2 X& M5 w0 M4 W5 r
117.6 Decorative-lighting strings

3.灯束上的电线是24AWG的,是否符合section 6电线的要求呢?我个人理解因为变压器输出是特低电压,所以电线线径只要符合电流的大小就可以了.但是从标准来看,似乎没有免除条款,至少也要22AWG以上,是吗?% [: @2 R) e) B" |2 f- B; |$ U

4.这个产品包装上标的是OUTDOOR USE的,那么电线是不是只能是section 6里的SPT-1W, SP-2W, SPT-2W, STW, SEW, SOW, SOOW, SJTW,SJEW, SJOW, or SJOOW.这几种线?如果只是indoor use,是否任何线型都可以?

5.最后一个问题是以前碰到的一个CASE,一直没弄清.产品是常见的灯串,但是灯泡是带过流丝(lamp shunt)的push-in bulb,并且产品插头中带3A保险丝.这种产品是否需要符合83A Cascading Lamp Temperature Test的要求呢? a6 E. L- h5 p! B0 {. V9 b
